Why buy this topper
Built for campers, travel trailers, fifth wheels, and motorhomes
RV mattresses are thin, firm, and rarely a standard size. This topper is cut to the sizes RVs actually use so it fits without bunching or overhang.
- Gel-infused, perfected over yearsWe have poured and refined this foam for years. The gel is blended through it, not sprayed on, so it stays cool for the life of the topper.
- Sleeps cool, responds fastOpen-cell foam lets heat escape, and it recovers as you move so you never feel stuck.
- Built to lastDense, consistent foam that holds its shape for 5 to 10 years. Cheap imports flatten in one.

The LOUNJ difference
We're the factory
Most bedding brands buy foam from a catalog and put their name on it. We built a factory instead. Every step happens under our roof in Phoenix, Arizona: chemistry, pouring, curing, cutting, quality check. That is why we can tell you exactly what is in this product, price it without a middleman, and stand behind it for years.

True RV sizes
Cut to fit your rig, not a house bed
RV mattresses are shorter and narrower than residential sizes and often have a notch or radius corner. We stock twelve RV sizes and cut anything else to order.

|---|---|---|
| Short Queen | 60 x 75 | The most common RV bed: travel trailers, fifth wheels, Class C |
| RV Queen | 60 x 80 | Residential queen length in newer fifth wheels |
| RV Queen | 59 x 79 | Older trailers and some Class A coaches |
| RV King | 72 x 80 | Fifth wheels and Class A with a king slide-out |
| Short King | 72 x 75 | Class A coaches with a shorter bedroom |
| Three Quarter | 48 x 75 | Vans, small trailers, older campers |
| RV Full | 53 x 75 | Truck campers and small trailers |
| Bunk | 28 x 73, 28 x 75, 30 x 75, 30 x 80, 35 x 75, 35 x 79 | Bunkhouse trailers and toy haulers |

Questions people ask
What size RV mattress topper do I need?
RV beds use their own sizes: short queen (60×75), RV king (72×80), short king (72×75), three quarter (48×75), and several bunk sizes. Measure your mattress top surface before ordering, since manufacturers vary by an inch or two. We stock 12 RV sizes and can cut anything else to order.
Can I order a custom size RV topper?
Yes. Send us width, length, and thickness through the custom size page and we will quote it within 1 to 2 business days. We cut in half-inch increments.
How thick should an RV mattress topper be?
Most RV mattresses are thin and firm, so 3 inches is the sweet spot for the biggest comfort upgrade. Choose 2 inches if your bed has low clearance under a cabinet or you want a lighter feel, and 4 inches if the mattress is very worn or you sleep on your side and want deep pressure relief.
Will it help with back pain from a firm RV mattress?
Extra cushioning and support relieves pressure points and helps keep your spine in a neutral position, which is usually what makes a firm or worn RV mattress uncomfortable. If you prefer a firmer feel, our Firm Mattress Topper is available in standard sizes and any RV size by custom quote.
Does it ship compressed? How long to expand?
Yes. Allow 24 to 48 hours to fully expand after unboxing, longer in cold weather. It is fine to sleep on it the first night.
Are your RV toppers safe and non-toxic?
Yes. CertiPUR-US certified gel memory foam, fiberglass free, no fire-retardant sprays, low odor, and made in our Phoenix factory.
Do you offer a sleep trial or warranty?
Both. 30-Night Happiness Guarantee with free returns, plus a 5-year warranty against defects.
