The Casper Select is a Costco-exclusive 12-inch memory foam mattress featuring four layers of premium foam construction designed for optimal comfort and support. The mattress includes a 1.5-inch breathable open-cell poly foam top layer, 1.5 inches of gel-infused memory foam for pressure relief, 1.5 inches of transitional poly foam for zoned support, and a 7.5-inch high-density support foam base.

This medium-firm mattress (rated 6.5 out of 10 firmness) provides balanced support suitable for most sleeping positions with excellent edge support and minimal sinkage. The hand-sewn cover combines polyester, cotton, rayon, and lycra in a thin, breathable construction with zipper removal for easy cleaning. The mattress measures 72" W x 84" L x 12" H and weighs 102 lbs.

All foam materials are CertiPUR-US certified, manufactured without ozone-depleting chemicals and with low VOC emissions for indoor air quality. The mattress is best placed directly on a solid wooden platform bed frame or a bed frame with wooden slats. It arrives compressed in a "bed-in-a-box" format and comes with a 10-year limited warranty.
