The Sealy Sleepy's Firm is a king-size innerspring mattress built for back and stomach sleepers who want a flat, supportive surface. Individually wrapped coils cut down motion transfer, and gel foam layers add contouring and help move heat away from the body. It ships compressed in a box, so it sets up without a delivery crew. Against rival firm hybrids and all-foam beds, it leans traditional innerspring: supportive and bouncy rather than plush, with less sink-in than memory foam. Side sleepers and anyone wanting cushioning should look elsewhere.

Owners of firm Sealy and Sleepy's mattresses generally describe a supportive, no-sink-in feel that suits back and stomach sleepers. Complaints tend to center on the firmness being too much for side sleeping and on the bed feeling less cushioned than expected.
This is a firm king-size mattress from Sealy and Sleepy's. It has a firm feel with more support and less sink, and it is made for back and stomach sleepers.
The cover is a stretch knit rayon quilting layer. Beneath it, the comfort layer has 7/8" of gel poly foam in the quilt and 1.25" of firm foam. The gel foam layers contour to the body and relieve pressure. The gel foam also helps pull heat away from the body and increases airflow.
The support system uses individually wrapped coils to reduce motion transfer. The mattress ships in a box for easy setup.
