This is a 12-inch hybrid memory foam mattress in California king size. Layers of foam conform to the body and spread weight evenly to ease pressure points. Hundreds of individually wrapped pocket springs limit motion transfer and noise, so a partner's movement is less likely to disturb sleep.
The foams are CertiPUR-US certified, and the mattress cover is OEKO-TEX certified. The mattress fits most common bed frames, including platforms, box springs, flat frames, slat bases, bunk beds and the floor.
It arrives vacuum-sealed in a box. To set it up, unbox it, unwrap it and give it up to 48 hours to expand. It comes with a 10-year warranty.
