Olee Sleep 12 inch euro box top mattress is designed to satisfy the need for contoured support of your vertebrae while you sleep. We owe this luxury to the tempered steel independently-encased coils whose particularity is to conform to the curves of your body creating an equal weight distribution, hence relieving any pressure points along your neck, shoulders, back and hips. Another advantage of independently-encased coils is the elimination of motion disturbance, so that if your partner moves throughout the night, you will never even know they are there. To ensure that this mattress lasts many years, its coils are protected by multi HD and memory foam layers which add to unparalleled quality and incredible comfort. The Perfect Combination of Cool I-Gel Memory Foam and pocketed innerspring base construction creates sound sleep experience. Dura Spring Base promotes proper back support and undisturbed sleep by combining continuous coil design with head to toe coil construction. Each coil pocketed for the stability and durability needed to provide support while absorbing motion.
