Is this mattress firm or medium?

The listing calls it firm, but the product highlights describe a medium feel, and owners report it ranges from soft to firm. Treat it as a medium-firm hybrid and expect some unit-to-unit variation.

Does it need a box spring?

No. It is a coil-and-foam mattress that works on a platform bed, slatted frame or adjustable base. A box spring is optional and mainly adds height.

How long until it fully expands?

Owners say it unboxes easily and expands quickly, but full expansion can take up to a couple of days. Sleep on it sooner if needed; the feel settles as it rises.

Is it good for back pain?

Buyers praise its back support, and the pocketed coils conform to the body. If you need a very firm surface, check the feel once it has expanded, since firmness varies.

Just the mattress, compressed and rolled in one box. No foundation, box spring or tools are included.

Can two adults sleep on the full size?

A full is 54 inches wide, which is snug for two adults. The 500 lb weight limit covers most couples, but side sleepers may prefer a queen for room.
