The Blinddarm King is a 14-inch hybrid mattress that pairs layered memory foam with individually wrapped pocket springs. The foam cushions pressure points while the coils limit motion transfer, so a restless partner is less likely to wake you. Foams are CertiPUR-US certified and the cover is OEKO-TEX certified. It ships vacuum-sealed in a box and works on platforms, box springs, slat bases, bunk beds and floors. Against all-foam rivals it adds spring support and airflow; against premium hybrids it is a simpler build with a 10-year warranty.

This is a 14-inch hybrid King mattress that combines layered memory foam with individually wrapped pocket springs. The foams conform to the body and distribute weight evenly, which helps relieve pressure points.
The pocket springs are wrapped individually to limit motion transfer and noise, so movement on one side is less likely to disturb a partner. 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 and bunk beds. It can also be used on the floor. It arrives vacuum-sealed in a box. Unbox it, unwrap it and allow up to 48 hours for it to expand.
