Hybrid Gel Foam Pocketed Coil Mattress Medium Firm Support for Spinal Alignment

Twelve inches of thoughtfully layered construction give this Twin XL hybrid mattress a sleep surface that works for a wide range of body types and sleep positions. Gel-infused foam and contouring layers handle pressure relief at the top, while an 8-inch pocketed coil system underneath delivers the kind of zoned, responsive support that keeps the spine aligned through the night. The medium-firm feel threads the needle between plush and stiff — cushioned enough for side and combination sleepers, supportive enough for back sleepers who need lumbar reinforcement. A reinforced coil perimeter means the edges hold firm whether you're sitting up to read or sleeping close to the side.

• Dimensions: 80 L x 38 W x 12 inches H (Twin XL)
