FoamTouch 6'' x 36'' x 72'' to 6 inch x 48 inch x 80 inch Bunk Mattress,
✅ PROS
- Real custom sizing from 36x72 up to 48x80 — fits odd bunk frames without gaps
- 6-inch profile strikes a solid balance between support and bunk rail height
- Quilted cover and medium-firm feel at a price well under big-box brands

- No handles or compression-tight packaging — moving it into tight stairwells is awkward
- Off-gassing smell lingers 24-48 hours despite the 'low VOC' claim
- Fiberglass-free fire sock shifts if you remove the cover for washing
The Verdict
Let’s be blunt: buying a bunk mattress online is a gamble. Standard sizes rarely fit those weird built-in bunk frames, and you’re stuck guessing whether the foam will feel like a brick or a marshmallow. The FoamTouch 6-inch bunk mattress takes a swing at both problems — and mostly connects.
What you’re actually getting
The headline feature here is the sizing. FoamTouch builds this mattress in any dimension between 36" x 72" (a short twin) and 48" x 80" (a full long). That’s not just marketing — you punch in your exact measurements at checkout, and they cut the foam to spec. For anyone with a custom-built loft bed or an RV bunk with weird proportions, this is the whole ballgame.
The mattress itself is a 6-inch stack of high-density polyurethane foam with a 1-inch quilted, breathable cover on top. You’re not getting memory foam contouring here — this is a firmer, more traditional feel. The cover is removable and washable, which matters for kids’ bunks where juice spills and bedwetting are inevitable.
Real-world performance
The medium-firm density is the right call for a bunk. It’s supportive enough that a 200-pound adult won’t bottom out, but soft enough that a 40-pound kid isn’t sleeping on a board. Multiple buyers describe it as “hotel firm” — not plush, not hard. If your kid likes sinking into a mattress, this won’t be it. But for back support and for stacking two bunks without the top mattress sagging into the lower one, it’s solid.
One thing that surprised reviewers: the edge support. Even at 6 inches, the foam holds its shape along the perimeter. Kids rolling to the edge of a top bunk won’t feel like they’re about to tip over. That’s a legit safety consideration that many cheaper foam mattresses get wrong.
What owners consistently praise
The custom sizing is the runaway winner in the feedback. One buyer wrote, “Our bunk frame is 37.5” wide — nothing standard fits. This came in at exactly 37.5" and sits flush with zero gaps." Another parent noted, “We ordered the 6x36x72 for a camper bunk and it fit like it was made by the same factory.” When the measurements are right, it’s a perfect fit.
The price is the second most-cited plus. FoamTouch undercuts most national brands by 30-40% on comparable custom sizes, and buyers repeatedly mention the value for a kids’ room where the mattress will get jumped on for five years.
Where it falls short
The off-gassing is real. Despite the “CertiPUR-US” and low-VOC claims, the foam arrives with a noticeable chemical smell that takes a day or two to dissipate. Plan to air it out in a well-ventilated room before the first sleep.
The 6-inch height is also a tradeoff for heavier adults. If you’re over 220 pounds, you’ll feel the support layer compress noticeably. This is a kids’ bunk mattress — don’t buy it as a primary adult bed and expect luxury.
Finally, the cover zips off for washing, but the fire sock underneath is loose. One reviewer warned, “I washed the cover and the white fire barrier slipped sideways. Had to wrestle it back into place.” If you’re not handy, that’s a frustrating 20 minutes.
Who should buy this
- Parents with custom bunk frames — this is the only practical option if standard sizes leave gaps
- RV and camper owners — the 36" x 72" size fits most narrow bunks perfectly
- Budget-conscious families — you’re paying half of what a brand-name mattress costs
Skip it if you need a plush, sink-in feel, or if the sleeper is a heavy adult. Also skip if you can’t tolerate any initial odor — this one needs airing out.
FAQ
Is this mattress actually 6 inches thick? Yes, the foam core is a full 6 inches. Some buyers measured 5.75" due to the cover compression, but it’s within normal tolerance. The height works well for standard bunk rails.
Can I use it on a regular bed frame? Technically yes, but it’s designed for tight spaces. On a standard twin frame, it’ll feel firm and low-profile. It’s fine for guest rooms, just don’t expect plush comfort.
How long does the smell last? Most buyers report 24-48 hours with the cover off in a ventilated room. It’s not the worst off-gassing I’ve seen, but it’s definitely present.
The Verdict
Buy it if you’re fighting a non-standard bunk or RV frame and need a custom fit without the custom price tag.
Skip it if you want plush comfort or a zero-odor unboxing experience.
The FoamTouch 6-inch bunk mattress earns its 4.6/5 score through sheer practicality. It’s not fancy, but it solves a real problem — fitting oddly-sized bunks with a firm, safe, affordable mattress. For its intended purpose, it’s the right purchase.
