This bed completely exceeded our expectations! We were a bit nervous when the box came and it was small and compressed, however we were blown away once it was out and regained its full size. It is incredible comfortable and well made!! Our daughter LOVES it!. Kathy. Midwest. Tue, 03 Nov 2026

Expertly handcrafted, the Organic Latex Mattress is made with carefully selected premium materials, including GOLS-certified organic latex, GOTS-certified organic wool, and a soft, breathable cover of GOTS-certified organic cotton. Available in both 9-inch and 12-inch profiles, as well as soft, medium, and firm comfort options, it’s designed to suit a variety of sleep preferences. Known for its balanced feel, this mattress delivers exceptional comfort, pressure relief, and dependable support for a truly restful night’s sleep.

The MagniCool 10 Soft is crafted to keep the body and mind cool while delivering a gentler, cozier comfort feel. Magniflex's exclusive MagniCool cover fabric helps create a fresh, breathable microclimate, while Aquabreeze and Elioform layers provide soft support with everyday comfort.

This 8" mattress has a tight top, edge support, and low-motion transfer, so it's designed to let you stay asleep, even if you or your partner toss and turn. With layers of gel memory foam, this mattress offers a firm feel, so it's great for those who need plenty of support to sleep. It also arrives compressed inside a box, so we recommend giving it time to expand to its full size. Best of all, it's backed by a 10-year manufacturer's warranty. Because this mattress includes a non-removable cover, we recommend adding a topper to retain mattress freshness and mitigate stains.

Only had it a coupla weeks, but so far so good. Very comfortable. Chris. Branson West, MO. Tue, 08 Feb 2022
