Most mattresses make you choose. Firm enough to support you, or soft enough to actually sleep on. The Lincove Classic Memory Foam Mattress doesn't make you choose. At 12 inches, it's built in four layers: a cool gel-infused quilted top that's soft and temperature-regulating, a gel memory foam layer that cradles pressure points while pulling heat away from your body, a super soft foam layer for enhanced cushioning, a 6-inch comfort foam layer for contoured support, and a high-density foam base that keeps everything stable and durable long-term. Every foam layer is CertiPUR-US certified — independently tested and verified free of harmful chemicals and ozone depleters. Medium firmness works for all sleep positions. The all-foam construction virtually eliminates partner motion so you sleep through the night regardless of what's happening on the other side. The open-cell foam matrix keeps air circulating through the mattress for a consistently cooler sleep surface. Ships compressed in a box, expands to full size within hours. Available in Twin, Full, Queen, King, Cal King, and specialty sizes 44" and 48". Spot clean only. Made in USA. 5-year limited warranty. 30-day free returns.
