Best RV Mattress: Short Queen, RV King, Bunk and Custom Sizes

The best RV mattress for most beds is a 10-inch memory foam short queen, 60 by 75 in. Picks by bed size, sleeper type and climate.

The best RV mattress for most travel trailers and fifth wheels is a 10-inch memory foam short queen, 60 by 75 inches, such as the Live and Sleep Resort Classic. Measure the platform before ordering anything: an RV short queen is 5 inches shorter than the residential queen that every mattress ad is talking about.

What size mattress does your RV bed actually take?

Measure the platform, then match it to the RV size chart, because RV mattress dimensions are not residential dimensions. The four sizes that cause the most returns are the short queen (60 x 75), the true queen (60 x 80), the RV king (72 x 80) and the bunk, which has no standard at all. A residential queen is 60 x 80 and will not lie flat in a short-queen slide-out. A residential king is 76 x 80, four inches wider than an RV king, and will foul the nightstands on both sides.

RV size name Typical dimensions Residential equivalent Where you find it
RV bunk 28–35 in wide x 68–75 in long None Bunkhouse trailers, over-cab beds
RV twin 38 x 75 in Twin 38 x 75 Bunkhouse and Class B singles
Three-quarter 48 x 75 in None Older campers, some toy haulers
RV full 53 x 75 in Full 54 x 75 Small trailers, Murphy beds
RV short queen 60 x 75 in Queen 60 x 80 The most common RV bed by far
RV queen (true) 60 x 80 in Queen 60 x 80 Newer fifth wheels, Class A
RV king 72 x 80 in King 76 x 80 Front bedrooms in fifth wheels

Two measurements matter beyond length and width. The first is the corner cut: many walkaround queens in a slide-out have one or both foot corners angled to clear the slide mechanism, and a rectangular mattress in that bed rides up the angle instead of sitting down in it. The second is the lid, if your bed lifts on gas struts for storage, since every inch of extra mattress thickness is an inch the lid has to swing through. The full size-by-size breakdown, including Olympic and Cal king variants, lives on the RV mattress sizes chart.

How to choose an RV mattress for your situation

Pick by the constraint you cannot change: your bed’s size, its clearance, and how many nights a year you sleep on it. Firmness is the last decision, not the first.

Your situation What to buy Why this and not the obvious choice
Couple in a 60-inch-wide short queen 10–12 in memory foam, medium-firm Foam absorbs the other person turning over. On 30 inches each, an innerspring transmits it to your side of the bed
Side sleeper with hip and shoulder pain 10 in gel memory foam, medium Under 8 inches of foam, a 180 lb side sleeper compresses the comfort layer flat and lands on the base
Hot climate or a bed against a slide wall Gel-infused or open-cell foam, 10–12 in Dense memory foam holds body heat. Gel and airflow channels move some of it, though nothing beats a shaded window
Bunkhouse for kids 5–6 in foam, cut to the exact bunk width Bunk gaps run 24–30 in. A thick mattress turns a bunk into a crawl space
Weekends only, under 30 nights a year 8 in foam You will not compress 8 inches in a season of weekends, and the payload saving is real
Full-time or seasonal site 12 in foam or a hybrid 200-plus nights a year is residential duty. Buy for a residential lifespan
Lift-up bed with storage underneath 8–10 in, and check strut travel Struts sized for a 5-in factory mattress often will not hold a 12-in one up
Murphy bed or dinette conversion 6 in maximum, foam The bed has to fold into a cabinet that was measured around the original mattress
Odd shape, corner cut or an angled nose Custom-cut foam slab No stock size fits a cut corner, and forcing one creates the ridge you feel under your knee

Weight belongs in this decision too. A 12-inch short queen foam mattress runs roughly 65–80 lb against about 30 lb for the factory slab you are throwing out, so you are spending 40 lb of cargo capacity on sleep. In a half-ton-towed trailer with 1,200 lb of payload left, that is worth knowing before the water tank is full.

The eight RV mattresses compared

MattressThicknessFeelPrice bandBest for
10 in Medium-firm memory foam $$ Short queen replacement, couples
12 in Medium, deep contour $$ Full-timers and heavier sleepers
10 in Medium memory foam $$ Sold in RV sizes, walkaround queens
12 in Medium, gel cooling layers $$$ Desert and southern summers
8 in Firmer, shallow contour $ Weekend rigs and guest bunks
10 in Medium, gel-infused $$ Side sleepers
5 in Firm, thin $ Bunks, Murphy beds, dinettes
9 in Eurotop, closest to a home bed $$ Owners who dislike the memory foam sink

Every mattress here ships compressed and rolled in a box that fits through a 30-inch RV door, which matters more than it sounds. A conventional mattress cannot be walked around a bedroom slide, past a wardrobe and onto a platform that has 6 inches of clearance on three sides. Check the size dropdown for Short Queen on each listing before you order, because most of these models are sold in residential sizes as well and the 60 x 80 version will not fit.

Live and Sleep Resort Classic: the short queen replacement to buy first

Our pick

Live and Sleep Resort Classic RV Short Queen Memory Foam Mattress

Live and Sleep
4.5
Price band $$
Best for: Couples replacing the original mattress in a short queen bed

The factory mattress in a travel trailer is a cost line, not a sleep product. Most are 4 to 5 inches of low-density polyurethane foam, and they compress permanently in about two seasons of use, which is why so many owners describe waking up in a trough. The Resort Classic is the straight swap for that: a purpose-built RV short queen with 10 inches of foam over a support base.

Three things make it the default. It arrives in the RV size rather than a residential 60 x 80 that you have to saw 5 inches off. Its medium-firm surface keeps your hips from dropping the way a plush 12-inch build does, which matters when the bed sits on plywood rather than a sprung base. And the memory foam comfort layer isolates motion, so the person who gets up at 5 a.m. to move the truck does not wake the other one.

Who should skip it: anyone camping in Phoenix in August. This is a conventional memory foam build, and it sleeps warmer than the gel options here. Bunkhouse owners should also look past it, since 10 inches is too tall for most bunk gaps.

What it fixes
  • Made in the 60 x 75 RV short queen shape, not cut down from a residential blank
  • 10 in of foam is enough that a 200 lb sleeper does not reach the base layer
  • Medium-firm, which suits back and combination sleepers without punishing side sleepers
Where it falls short
  • Foam holds heat compared with a gel or hybrid build
  • Needs 24 to 72 hours to reach full thickness after unboxing
  • At roughly 55 to 65 lb, it is a two-person job to get onto a slide-out platform

Zinus 12 Inch Green Tea: depth for two adults on 60 inches of width

Upgrade pick

Zinus 12 Inch Green Tea Memory Foam Mattress

Zinus
4.5
Price band $$
Best for: Full-timers and couples over 200 lb who bottom out thinner foam

Two adults sharing a short queen have 30 inches each, roughly the width of a standard door. At that width every movement is transmitted, and the thickness of the foam is what decides whether you feel your partner shift or sleep through it. Twelve inches is where that changes for most couples.

The specifics that matter here: a 12-inch profile with a memory foam comfort layer over high-density support foam, castor natural seed oil and green tea extract infused into the foam to slow odor buildup, and a 10-year limited warranty that is unusual at this price band. That odor point is not marketing fluff in an RV, a sealed trailer in a humid climate develops a stale smell that gets into bedding first.

Before you buy it, take a tape to the bed. Twelve inches plus a mattress protector plus a fitted sheet is close to 13 inches of stack, and on a lift-up storage bed that is often the difference between a lid that latches and one that stands proud by an inch. If your platform is fixed, this is the depth to get. If it lifts, drop to a 10-inch build.

What it fixes
  • 12 in gives a heavier sleeper 3 to 4 in of contour before reaching the support core
  • Green tea extract and charcoal in the foam target the closed-up smell of a rig stored since October
  • Zinus backs the line with a 10-year limited warranty
Where it falls short
  • 12 in can stop a lift-up bed lid from latching, measure strut travel first
  • Roughly 70 lb, and awkward to reposition alone in a bedroom slide
  • Deep contour reads as hot to some sleepers, especially without gel

Zinus Deluxe 10 Inch RV: a mid-depth foam sold in RV sizes

Zinus Deluxe Memory Foam 10 Inch RV Mattress

Zinus
4.0
Price band $$
Best for: Owners replacing a walkaround queen who want depth without a lid problem

The walkaround queen in a bedroom slide is the fussiest bed in an RV. You have 6 inches of walkway on two sides, a wardrobe at the foot, and no way to flip a mattress once it is in place. What you want there is a mattress that arrives compressed, expands in position, and never needs turning.

This one is built for that job at 10 inches, which is the depth that clears most storage lids while still putting real foam between you and the platform. Its memory foam layer is medium, so a side sleeper gets shoulder relief without a back sleeper sinking into a hammock. And because it is listed as an RV mattress, the RV short queen size appears in the size selector rather than requiring a foam shop.

It is the wrong mattress for a hot-climate rig. There is no gel infusion or airflow channel here, and dense foam against an uninsulated slide wall in July gets warm. Anyone under a metal roof in Texas should pay the difference for the Cool Breeze instead.

What it fixes
  • 10 in sits under most bed-lid clearance limits with a sheet and protector on top
  • Sold under an RV label, so the short queen option is on the listing rather than a special order
  • Medium memory foam feel suits back and side sleepers in the same bed
Where it falls short
  • No gel layer, so it is not the pick for a summer in the south
  • Foam edges compress under a sitting adult, awkward on a bed you sit on to put boots on
  • Same 24 to 72 hour expansion wait as every boxed foam mattress

DynastyMattress Cool Breeze 12-Inch: for beds that sit against a hot wall

Best for hot climates

DynastyMattress Cool Breeze 12-Inch Gel Memory Foam Mattress

DynastyMattress
4.5
Price band $$$
Best for: Snowbirds and summer campers in Arizona, Texas and Florida

The bedroom is the hottest room in most RVs. It is usually at the far end from the roof air conditioner, it often sits over the front cap or a slide with thin walls, and it is the room you occupy for eight hours while the sun heats the sidewall. Sleeping on dense memory foam in that room in July is like sleeping on a warm plate.

The Cool Breeze answers it with gel-infused memory foam in the comfort layer, a 12-inch total profile, and a layered build that puts the cooling foam where your body touches it. In practice you are buying a slower heat curve: the surface takes longer to warm to body temperature, so the 2 a.m. flip to the cool side of the bed happens less often.

Be realistic about what foam can do. If the bedroom is 88 °F at midnight, this mattress will not fix that, and the higher-value fix is stopping the heat at the window with blackout and thermal RV window shades. Anyone camping in the mountains or storing the rig from October to April is paying for a feature they will not use.

What it fixes
  • Gel-infused memory foam moves heat away from the contact surface instead of storing it
  • 12 in build layers a cooling top over high-density support foam
  • Sold in RV short queen alongside residential sizes
Where it falls short
  • Highest price band here by a clear margin
  • 12 in of foam is roughly 75 lb and it does not bend around a slide corner
  • Gel slows heat buildup, it does not make a warm bedroom cool

Best Price Mattress 8-Inch: the honest budget replacement

Budget pick

Best Price Mattress 8-Inch Memory Foam Mattress

Best Price Mattress
4.0
Price band $
Best for: Weekend campers, guest bunks and seasonal trailers on a fixed budget

There is a habit among RV owners of buying a 3-inch topper for a failed factory mattress, which costs most of the price of a real 8-inch mattress and leaves the collapsed foam in place underneath. You then sleep on a soft layer over a hard dip, which is the specific recipe for lower back pain.

This is the mattress that makes throwing the old one out affordable. Eight inches of foam, a firmer surface than the 10 and 12-inch builds, and a weight around 45 lb that one person can carry through a trailer door and drop onto a bunk platform without help. For a rig that gets used twelve weekends a year, that is the whole job done.

The limits are exactly where you would expect. Eight inches does not have the depth to keep a heavy side sleeper off the base, and it does not isolate motion the way a 12-inch build does. If you are living in the rig, spend more once instead of twice.

What it fixes
  • 8 in is enough to stop a weekend sleeper feeling the platform
  • Around 45 lb, so one person can wrestle it onto a slide-out bed
  • Cheapest way to remove the factory slab entirely rather than covering it
Where it falls short
  • A sleeper over about 220 lb will reach the support core on their side
  • Thin comfort layer means less motion isolation for couples
  • Not built for 200 nights a year

LUCID 10 Inch Gel Memory Foam: shoulder and hip relief for side sleepers

Best for side sleepers

LUCID 10 Inch Gel Memory Foam Mattress

LUCID
4.5
Price band $$
Best for: Side sleepers who wake with a numb arm or an aching hip

Side sleeping puts your entire body weight through two contact points, the shoulder and the greater trochanter of the hip. On a 4-inch factory mattress those two points compress the foam flat and press onto the plywood, and you wake up rolling onto your back with a dead arm. The fix is depth in the comfort layer, not firmness.

Ten inches with a gel-infused memory foam top is the accessible version of that fix. The comfort layer lets the shoulder drop while the denser base keeps the hips level, which is what stops the spine bending sideways at the waist. Gel infusion takes some of the heat penalty out of the deal, and the 10-year warranty is worth reading before you compare it against an unbranded foam slab with none.

Stomach sleepers should not buy this. A medium foam surface lets the hips sink first, which arches the lower back all night, and the firmer 8-inch build is the better match. Couples with a big weight difference should also consider the 12-inch options, which handle mismatched loads better.

What it fixes
  • Gel-infused memory foam comfort layer over high-density base, the standard build for pressure relief
  • 10 in of depth lets a shoulder sink without the hip following it down
  • LUCID lists a 10-year warranty across the line
Where it falls short
  • Medium feel is too soft for stomach sleepers, who need the hips held up
  • Boxed foam takes up to 48 hours to reach full loft and shape
  • Gel helps with heat, it is not the equal of a hybrid with a coil layer

Zinus 5 Inch BioFusion: the bunk and Murphy bed answer

Best for bunks

Zinus Memory Foam 5 Inch BioFusion Mattress

Zinus
4.0
Price band $
Best for: Bunkhouse families, Murphy beds and dinette conversions

Bunk beds fail on geometry rather than comfort. A child who can sit up in their bunk under a factory 3-inch pad cannot sit up under a 10-inch mattress, and the first thing you hear about it is a head hitting the bunk above at 6 a.m. Bunk gaps in most bunkhouse trailers run 24 to 30 inches, so mattress thickness is a headroom budget.

Five inches spends that budget sensibly: enough memory foam to stop a bunk slat pattern printing on a child’s back, thin enough to leave 19 to 25 inches of sitting room, and light enough to pull out and air after a wet week. The same logic makes it the right pick for a Murphy bed, where the mattress has to fold into a cabinet sized around the original thin pad, and for a dinette that converts to a bed for guests.

It is not an adult’s main mattress. Five inches under a 200 lb sleeper is a support layer with a courtesy of foam on top. Also measure your bunks before ordering, because RV bunk widths run anywhere from 28 to 35 inches and a foam shop trim is often part of the job.

What it fixes
  • 5 in preserves sitting-up room in a bunk gap that is often only 24 to 30 in
  • Light enough for a child to handle when a bunk mattress needs airing out
  • Folds and stows more easily than a 10 in slab in a Murphy bed cabinet
Where it falls short
  • Too thin for an adult's main bed, you will feel the platform
  • Bunk widths vary so much that stock sizes often need trimming
  • Thin foam compresses faster under repeated use than a 10 in build

Dreamfoam Doze 9 Inch Eurotop: for people who hate the memory foam sink

Dreamfoam Bedding Doze 9 Inch Eurotop Mattress

Dreamfoam Bedding
4.0
Price band $$
Best for: Owners who want a home-mattress feel rather than a body-hugging one

Some people simply do not like memory foam. The complaint is consistent: it feels like the mattress is holding you in position, and turning over means climbing out of a mold of yourself. If your home bed is an innerspring and you sleep badly on foam, buying a 12-inch memory foam RV mattress is buying the problem twice.

The Doze answers that with a eurotop, a padded upper layer sewn flush to the edge rather than a rolled pillow top, over a foam core. The result is a surface you lie on rather than sink into, at 9 inches, which is a workable depth for a fixed RV platform. Dreamfoam builds mattresses to order, and that build-to-order model is the reason non-standard sizes exist in this corner of the market at all.

The trade-off is motion. A responsive surface passes movement across the bed, and on a 60-inch short queen that is the thing memory foam owners bought foam to avoid. If your partner is a restless sleeper and the bed is narrow, take the Zinus 12-inch instead.

What it fixes
  • Eurotop construction gives a padded surface without the slow sink of deep memory foam
  • 9 in fits between the 8 in budget builds and the 12 in full-time builds
  • Dreamfoam builds to order, which is why odd sizes exist in the range
Where it falls short
  • Less motion isolation than a solid memory foam mattress
  • A eurotop adds surface height that a lift-up bed lid still has to clear
  • Made-to-order means longer lead times than a warehouse item

How thick should an RV mattress be?

Eight to 12 inches for an adult’s main bed, and 5 to 6 inches for a bunk or a Murphy bed. Factory mattresses are usually 4 to 5 inches, which is the number to beat, not the number to match.

Three ceilings decide the number for your rig. The first is the bed lid: gas struts specified for a 5-inch pad may not hold a 12-inch mattress open, and the lid can drop on your hands while you are loading the storage bay under it. The second is bedroom slide clearance, since a mattress that stands proud of the platform edge catches on the slide fascia as it comes in. The third is the sheet, because a 12-inch mattress needs deep-pocket fitted sheets in an RV size, and standard queen sheets will not stay on the corners of a short queen or RV king bedding set.

Thicker is not automatically better sleep. A 12-inch mattress on a solid plywood platform with no ventilation traps more moisture underneath it than an 8-inch one, and the heavier the mattress, the harder it is to lift and dry out the underside in a humid autumn.

Memory foam, latex, hybrid or innerspring in an RV?

Memory foam wins in an RV for three practical reasons: it ships compressed through a narrow door, it is quiet over rough roads, and it isolates motion on a bed only 60 inches wide. Latex and hybrids are legitimate choices with real trade-offs; a standard innerspring is usually the wrong tool.

Memory foam. Ships rolled in a box, expands in place, no springs to squeak on a washboard forest road, and it holds nothing that rattles. Its weakness is heat and moisture: closed-cell foam stores body heat, and it does not breathe through the bottom, which is what makes condensation under the mattress an RV-specific problem.

Latex. Breathes better than memory foam and bounces back faster, so turning over is easier. It also weighs the most of any option, and a latex short queen can push past 90 lb, which is real payload and a genuinely difficult item to carry through a trailer door.

Hybrid (coils plus foam). Best airflow of the four, because air moves through the coil layer, and the closest feel to a home mattress. The catch in an RV is that coils are noisier as the rig flexes and heavier than an all-foam build, and hybrids in RV-specific sizes are far less common on the shelf.

Innerspring. This is what the factory fits in older units, and it is the one to walk away from. Springs work loose over years of road vibration, an individual broken coil ends up under your shoulder blade, and the open cavity inside a spring unit is where damp and odor collect.

Where do you buy an RV mattress, including custom sizes?

Amazon and RV parts retailers cover the stock sizes, and a local foam fabricator covers everything else. Short queen (60 x 75) is stocked widely; RV king (72 x 80), three-quarter (48 x 75) and bunk sizes are where stock supply thins out fast.

  • Stock RV sizes. Short queen, RV queen and RV king are sold by mainstream foam brands with the RV size in the dropdown. This is the cheapest route and the one with a returns policy behind it.
  • RV dealers and parts stores. Camping World and independent RV supply stores keep short queen mattresses on the floor, usually at a higher price than online, with the advantage that you can lie on it first and take it home the same day.
  • Made-to-order foam brands. Several boxed-mattress makers, Dreamfoam among them, build each order rather than pulling from stock, which is why non-standard sizes turn up in their range at all. Lead times run longer than a warehouse item.
  • Local foam fabricators. Any upholstery foam shop will cut a slab to your dimensions, including an angled corner, and glue a memory foam topper to a support base. This is the only real answer for a cut-corner bed, a boat-style nose bunk or a 1990s camper with a size nobody makes any more.

For a custom cut, give the shop the platform dimensions, not the old mattress dimensions. A mattress that has spent eight years in a bed has shrunk and deformed at the corners, and copying it reproduces the gap you have been jamming a towel into. Measure the platform at its widest and longest points, note any corner angles with two measurements from the corner, and order to the platform.

How to make an RV mattress more comfortable without replacing it

If the mattress is sagging, a topper hides the problem for one season and no longer. If the mattress is sound but the sleep is bad, four fixes are worth doing before you spend anything: add support, add a topper, stop the sliding, and get air under the mattress.

  1. Check what the mattress is lying on

    Lift the mattress and look. Bare plywood with no ventilation is the usual find; bowed slats or a broken support rail is the second. Expected: a flat, dry, solid surface with no visible dip in the middle.

  2. Add a support layer before a comfort layer

    A 1/2 in plywood sheet over sagging slats, or new slats at 3 in spacing, costs about $30 and fixes the dip that a topper only disguises. Expected: no visible sag when you press the middle of the platform.

  3. Fit a ventilation underlay

    A 3/4 in open mesh matting such as Hypervent, or a set of cedar slats with 1 in gaps, lets air move under the foam. Expected: no damp patch or black speckling on the underside at the next check.

  4. Add a 2 to 3 in topper only if the mattress is still flat

    A gel or memory foam topper adds pressure relief to a firm but intact mattress. Expected: hips no longer ache after six hours.

  5. Stop the mattress sliding on the platform

    A non-slip rug pad cut to the platform, or four hook-and-loop strips at the corners, stops the nightly creep toward the foot of the bed. Expected: the mattress is where you left it after a travel day.

Condensation under an RV mattress is the failure mode most owners meet exactly once. Two adults give off around a pint of moisture a night. That moisture passes down through the foam, hits plywood that is 15 °F colder because it is above an unheated storage bay, and condenses. Three weeks later you lift the mattress to find black speckling across the underside, and no amount of scrubbing gets it out of the foam. Ventilation matting is the cheap prevention, and it belongs under any mattress in a rig used in cold weather. If it has already happened, deal with the source before the smell, because getting musty odors out of an RV is impossible while wet foam is still in the bed.

The topper route has one honest use case: a mattress that is firm and flat but harsh, usually in a rig under three years old. In that case a 3-inch RV mattress topper in short queen or RV king is a legitimate fix that costs a third of a new mattress. On a collapsed factory slab it is a season of denial.

FAQ

Frequently asked questions

What is the best RV mattress for couples?

A 10 to 12 inch memory foam mattress in the correct RV size, such as the Live and Sleep Resort Classic at 10 inches or the Zinus Green Tea at 12 inches. On a short queen each person has only 30 inches of width, so motion isolation matters more than in a residential bed. Deeper foam absorbs a partner turning over; innersprings and thin foam transmit it.

What size is a queen RV mattress?

An RV short queen is 60 x 75 inches, five inches shorter than the 60 x 80 residential queen. Some newer fifth wheels and Class A coaches use a true queen at 60 x 80. Measure the platform rather than trusting the brochure, and check whether the foot corners are angled to clear a slide-out mechanism.

What is an RV king mattress?

An RV king is typically 72 x 80 inches, four inches narrower than a residential king at 76 x 80. Some coaches use 72 x 75. Residential king sheets are cut for 76 inches of width and will not hold the corners on an RV king, so buy RV king bedding rather than assuming your house set transfers.

How thick is an RV mattress?

Factory RV mattresses are usually 4 to 5 inches of low-density foam. Replacements run 8 to 12 inches for a main bed and 5 to 6 inches for bunks and Murphy beds. Before ordering anything over 10 inches, check that a lift-up bed lid still latches and that the mattress does not stand proud of the platform edge in a slide-out.

Where can I find a custom-size RV mattress?

For an angled corner, a nose bunk or a discontinued size, a local upholstery foam fabricator will cut a slab to your measurements and laminate a memory foam layer on top. Several made-to-order boxed brands also produce non-standard sizes with a longer lead time. Give the shop the platform dimensions, not the dimensions of the deformed mattress you are replacing.

Does Consumer Reports rate RV mattresses?

Consumer Reports tests residential mattresses and does not publish a separate RV mattress ranking, so searches for a Consumer Reports RV mattress pick return roundups rather than lab results. Judge an RV mattress on the specifications you can verify: size, thickness, foam density, CertiPUR-US certification and warranty length.

How do I stop my RV mattress from sliding?

Cut a non-slip rug pad to the platform size and lay it under the mattress, or fix four hook-and-loop strips at the corners. Both stop the creep toward the foot of the bed on travel days. A ventilation underlay such as open mesh matting does the same job while also letting air move under the foam.

How long does an RV mattress last?

A factory foam mattress typically collapses in two to three seasons of regular use. A 10 to 12 inch memory foam replacement lasts closer to eight to ten years, and most carry a 10-year limited warranty. Full-time use compresses foam faster because the mattress sees 300-plus nights a year instead of 30.

Do I have to let a new RV mattress expand before sleeping on it?

Yes. Boxed foam mattresses need 24 to 72 hours to reach full thickness, and sleeping on one too early can leave a permanent depression. Unbox it on the bed platform, open a window and the roof vent, and let it air. New foam has an odor that fades over the same period.

Buy the size first, the feel second

Every mattress return in this category starts the same way, with a 60 x 80 queen ordered for a 60 x 75 bed. Measure the platform, write the numbers down, then choose between depth for a couple, gel for a hot climate and 5 inches for a bunk. When the new mattress goes in, spend the extra twenty minutes putting ventilation matting under it and fitted sheets on it that were cut for RV bedding sizes, because those two jobs are what keep it from smelling like the underside of a boat by spring. If your rig is due for more than a mattress, the rest of the bedroom and living space work is in the RV interior and furniture hub.
