Our take on the EDX 6'' Full Memory Foam Mattress in a Box
The EDX 6-inch Full mattress is an all-foam bed-in-a-box with a gel memory foam comfort layer over a high-density support base. It is CertiPUR-US certified and fiberglass-free, which matters for shoppers wary of cheap foam mattresses. At 6 inches it is a thin, firm-feeling mattress, best suited to kids, bunk beds, guest rooms and light sleepers rather than heavy adults. It competes on safety certification and a low profile, not on plushness or edge support.

Questions and answers
- Is this mattress good for side sleepers?
- It is firm and only 6 inches thick, so side sleepers may feel pressure at the shoulders and hips. Back and stomach sleepers, especially lighter ones, tend to do better on it.
- Does it contain fiberglass?
- No. The foam is fiberglass-free and CertiPUR-US certified, which covers low emissions and restricted materials.
- How long does it take to expand?
- Foam mattresses typically take 24 to 72 hours to reach full height. Some owners report this one stays slightly short of 6 inches.
- Can it go on a bunk bed or trundle?
- Yes. The 6-inch profile suits bunk beds, trundles and platform frames. It is not designed for an adjustable base.
- Is it good for a heavy adult?
- Probably not for daily use. The thin foam build gives limited support and edge support for heavier sleepers; it fits kids and guest rooms better.
