Is this mattress good for side sleepers?

Yes. The thick gel memory foam top layer cushions hips and shoulders, which suits side sleepers. Stomach sleepers may find it too soft.

Does the gel memory foam sleep cool?

It is designed to draw heat away better than plain memory foam, but it is still an all-foam bed. Hot sleepers may want a breathable mattress protector or a hybrid instead.

Does it need a box spring?

No. It works on a slatted bed frame, a platform base or an adjustable base. A solid, slatted foundation gives the foam the airflow it needs.

How firm is the Bestier 14-inch mattress?

It is best described as soft to medium. The 14-inch build adds plushness, so shoppers wanting a firm bed should look at a thinner or firmer foam model.

How long does it take to expand after unrolling?

Most foam mattresses like this one reach full shape within 24 to 72 hours. Sleeping on it sooner is fine, but the corners may take a little longer to rise.

Is it a good fit for couples on a king frame?

The king size gives couples plenty of room, but the soft foam transfers some motion and the edges are weak. Couples who want a firmer, more stable edge should consider a hybrid.
