The Five-Zone 1,166 Foam-Encased Pocket Coil Euro Top Mattress delivers exceptional comfort and support with a smartly designed 1.8mm and 2.0mm coil system that adapts to the body’s natural curves. Its five-zone pocket coils with lumbar zone comfort reinforcement provide targeted back support, while the 4” hard perimeter foam encasement ensures strong edge support and maximized sleeping surface. A plush Euro top with 3” medium-soft soy foam, 1½” medium-soft foam quilted with 20 oz hollow fiber, and a copper-infused gel layer with lumbar support pad work together to relieve pressure points and regulate temperature for cooler, more restorative sleep. Finished with a stretchable soft-hand copper fabric cover and a tufted border with black taped edges, plus 1” high-density foam layers at the top and bottom for added durability, this mattress offers the perfect balance of softness, stability, and long-lasting performance.
