Is this mattress good for side sleepers?

Probably not. It is a firm innerspring with a thin gel foam layer, and side sleepers usually need more cushioning at the shoulder and hip.

What sizes does it come in?

The listed size is California King, 84 by 76 inches. Check the specific listing for other sizes before ordering.

It is designed to run cooler than all-foam beds, with gel foam and a moisture-wicking cover over open coils. Owner reports are mixed but lean toward it sleeping cool.

Do I need a box spring?

An innerspring mattress like this works on a box spring or a slatted frame. A solid platform base is also fine.

Is it CertiPUR-US certified?

Yes. The foams are CertiPUR-US certified, which covers low emissions and restricted materials.

How does it compare with an all-foam mattress?

It is firmer and more supportive than most all-foam beds, and the open coils breathe better. It transfers more motion between partners and offers less pressure relief.

About the Sleepy's by Sealy Slumber Mattress Gel Foam

The Sleepy's by Sealy Slumber is a firm innerspring mattress with a gel foam layer and a tight top, sold in California King (84 by 76 inches). Individually wrapped tempered steel coils sit under the gel foam, and the cover is a moisture-wicking polyester blend; the foams are CertiPUR-US certified. It is built for shoppers who want a hard, supportive feel, and it competes on that firmness rather than on cushioning or motion isolation. Owner ratings are divided, with comfort and long-term durability the main sticking points.
