Is $183.99 a good price for this mattress?

It is a low price for a Queen gel memory foam mattress. Only Wayfair lists it new as of November 8, 2026, and there is no price history, so it is hard to say whether it drops lower.

Is this mattress good for side sleepers?

The medium firm feel is on the firmer side, which side sleepers often find too hard on the shoulders and hips. Back and stomach sleepers are the better match.

Does the gel foam really sleep cooler?

Gel infusion helps compared with plain memory foam, but an all-foam bed still traps more heat than a hybrid with coils. Hot sleepers should weigh that.

What sizes does it come in?

It is sold in Queen and Twin. Check the listing for the exact dimensions and thickness before ordering.

Does it need a box spring?

All-foam mattresses like this one usually work on a platform bed or slatted base. A box spring is not required, but a solid, supportive base helps it last.
