Is a 5-inch mattress thick enough for an adult?

It works for light adults and back or stomach sleepers who want a firm surface. Heavier adults and side sleepers will likely feel the base layer and want at least 6 to 8 inches.

Does it need a box spring?

No. It is designed to sit on a slatted base, and the maker says 14-slat Maxtrix beds need no bunkie board or box spring. Any slatted frame with closely spaced slats will do.

Is the cover machine washable?

Yes. The organic cotton cover is described as removable and machine washable. Check the care label, since the spec sheet also lists the cover as not removable.

Is it safe for kids and free of fiberglass?

It is CertiPUR-US certified for content, emissions and durability, and the fire barrier is made without fiberglass or chemical flame retardants. That makes it a reasonable choice for a child's bunk.

Our take on the 5" Memory Foam Mattress

This is a 5-inch gel memory foam mattress sold in a queen size (60 by 80 inches), built as a low-profile bed for bunk beds, trundles, RVs and kids' rooms. It uses a four-layer foam build with perforated, cooling gel-infused memory foam and a removable, machine-washable organic cotton cover, and it is CertiPUR-US certified with no fiberglass in the fire barrier. It is listed as firm, though the fill is described as plush yet firm, so expect a dense, supportive feel rather than a soft sink-in. At $83.71 at The Home Depot as of November 4, 2026, it sits at the low end of what a 5-inch queen foam mattress costs, and only two stores list it new.

What reviewers say

Only two ratings are on record, averaging 3.5 out of 5, so the sample is too small to draw firm conclusions. Buyers of thin bunk mattresses like this generally judge them on firmness and fit rather than long-term durability.

Pros

Fits low-clearance bunk and trundle frames
Firm support for kids

Cons

Thin padding for adults
Mixed satisfaction reflected in the 3.5 average
