Is the 8-inch medium firm enough for back sleepers?

Average-weight back and side sleepers usually find it supportive. Heavier sleepers often want a thicker mattress or a hybrid.

Does the cooling gel really keep you cool?

It sleeps cooler than traditional memory foam, but it is not actively chilled. Very hot sleepers may still feel warmth.

Most owners report it reaches full shape within 24 to 48 hours. Sleep on it sooner if you must, but expect it to feel firmer at first.

No. It works on a platform bed, slatted frame, adjustable base or the floor. A solid, flat base gives the best support.

Yes. The 8-inch profile is thin enough for most bunk beds and trundles, and it is light enough to lift.

Expect a few nights of adjustment. The foam softens slightly in the first weeks, and some owners notice a mild new-foam smell that fades.
