Curl up on the Eclipse 11 Memory Foam Mattress on rainy Sunday mornings and after harried workdays alike, and youll get the rest you need whether your days are hectic or luxuriously slow. This foam mattress favors simplicity over a wealth of extra features, and it uses a blend of foams to provide medium plush cushioning. A top layer of Open Cell Memory Foam breathes more efficiently than traditional closed cell foams, encouraging air to move through the mattress to regulate temperature rather than hang onto heat. Memory foams signature exacting softness will welcome you each time you lie down, conforming to your body and helping side and back sleepers relax free of pressure points. Though it feels soft, the Eclipse 11 includes a layer of stable Transition Foam as well as a sturdy, seven-inch High Density Foam core, which aligns and supports your spine and back as you sleep.Dimensions: Twin: 39 W x 75 L Twin XL: 39 W x 80 L Full: 54 W x 75 L Queen: 60 W x 80 L King: 76 W x 80 L Cal King: 72 W x 84 L.Jeffco 10 Year Limited Warranty.Comfort Level: 3.
