The FOLVUTY PrimeNest is a 14-inch king hybrid mattress that pairs over 1,000 individually pocketed coils with cooling gel memory foam, egg-crate breathable foam and graphene-infused support foam. It lands at a medium-firm feel with a 7-zone support layout aimed at shoulders, back, lumbar, hips and legs. The cover uses bamboo charcoal fiber fabric, and the coil base is meant to cut motion transfer for couples. Against other boxed hybrids, it leans on cooling layers and a thicker profile rather than a plush pillow-top feel, so it suits sleepers who want firm support with some contouring.

The FOLVUTY PrimeNest is a 14-inch King hybrid mattress in black with a medium-firm feel. It combines graphene-infused high-density support foam, cooling gel memory foam, egg-crate breathable foam and individually pocketed coils.
Graphene-infused foam helps conduct and disperse heat and strengthens the mattress core. The gel memory foam contours to the body, and the egg-crate foam lets air move through the comfort layers. A 7-zone ergonomic system supports the shoulders, back, lumbar area, hips and legs. The soft cover contains bamboo charcoal fiber.
More than 1,000 individually pocketed coils help reduce motion transfer. The mattress is made with CertiPUR-US certified foam and OEKO-TEX certified textiles, and it meets CFR 1633 fire safety standards. No fiberglass is used in the cover, foam layers, fire barrier or inner structure. It ships compressed in a box and needs 48 to 72 hours to fully expand.
