The Primenite 12" Memory Foam Mattress represents the top of the Primenite foam line — a full foot of mattress engineered for sleepers who prioritize deep comfort and long-term support. The 2.5-inch memory foam layer sits atop a 9.5-inch high-density base, creating a sleep surface that absorbs movement, relieves pressure at the shoulders and hips, and holds its shape night after night. Whether you’re a back sleeper, side sleeper, or share the bed with a partner, the extra depth makes a real difference in how rested you feel in the morning.
The 100% polyester top and side cover is built to last, and the non-slip bottom cover with zipper keeps the mattress locked in place on any platform bed, box spring, or adjustable base. An internal FR barrier meets the 16 CFR 1633 flammability standard, and CertiPUR-US certification means the foam has been independently tested — no harmful chemicals, no excessive off-gassing, and verified durability. At 12 inches, this is the mattress you buy when you’re done settling for less.
Ships compressed and rolled in a box for straightforward delivery and setup. Available in Twin, Full, Queen, and Eastern King.
