Is the LuckyLotus 12 Inch Hybrid good for side sleepers?

Yes. The Eurotop and gel memory foam cushion the shoulders and hips, which most side sleepers find comfortable. Stomach sleepers may find it too soft.

Does the gel memory foam actually sleep cool?

It runs cooler than plain memory foam for many owners, but it is not an active cooling mattress. Hot sleepers should still use breathable sheets and a cool room.

How firm is this mattress?

It sits on the softer side of medium thanks to the Eurotop. Firmness varies between units, so expect a plush feel rather than a firm one.

What size is the queen?

The queen measures 60 inches wide by 80 inches long, the standard US queen size. It is 12 inches thick, so deep-pocket sheets fit best.

Does it need a box spring?

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

How long does it take to expand after unrolling?

Most of the expansion happens within a day, and the mattress reaches full height in about 48 to 72 hours. Some owners notice an odor that fades over the first few days.
