The Purple Plus Mattress is the comfort upgrade that provides more dynamic support. Enjoy 2" of breathable GelFlex Grid to cradle pressure points like hips and shoulders while keeping the rest of your body fully aligned. The SoftFlex knit cover is designed to let you feel the complete instant response of the GelFlex Grid. The enhanced GelFlex Grid support gives you amazing sleep quality thanks to a three-layer premium foam base. The extra 2" layer of premium comfort foam responds more quickly to movement than our original foam, so every inch of you remains supported even as you shift or roll over. Enjoy a great nights sleep and wake up refreshed and ready for the day.
