Is the Sleepy's Sealy mattress good for hot sleepers?

It uses gel memory foam with temperature-regulating features, which is meant to sleep cooler than plain memory foam. All-foam beds still trap more heat than hybrids with coils and airflow.

What sizes does it come in?

Listings show queen and king sizes. Check the specific listing before ordering, since size labeling on this model is inconsistent.

Does it work on an adjustable bed?

Yes. The 10-inch all-foam build bends with adjustable bases, and the listing notes adjustable bed compatibility.

Is $489.99 a good price?

It is the best new price found as of November 7, 2026, at Mattress Firm, and only one store lists it new. With no competing listings, there is little room to beat that price.

How firm is the medium comfort level?

Medium is a middle-of-the-road feel that suits most back and side sleepers. Stomach sleepers and people who want a firm bed may find it too soft.

Our take on the Sleepy's Sealy

The Sleepy's Sealy is a 10-inch gel memory foam mattress sold in queen and king sizes with a medium comfort level. It pairs a memory foam fill with temperature-regulating gel to sleep cooler than basic foam, and its 10-inch profile works on adjustable bases. The best new price is $489.99 at Mattress Firm as of November 7, 2026, and only one store lists it new, so there is little price competition to shop around.
