Featuring a 3 zoned coil design, this mattress offers pressure relief and support where you need it, with a Cool Twist® Gel Memory Foam that contours to your body—with upgrades available with more cooling layers and support.
Benefits
Temperature-regulating components and materials draw heat away from the body to create a cool and comfortable sleep surface.
The goal of mattress motion separation is to isolate movement, helping to reduce what you feel (like your partner tossing and turning) and offer pressure relief to your shoulders, hips, and back.
Proper mattress support can alleviate common sleep problems from snoring to soreness to sleep apnea as it distributes your weight evenly across the mattress and maintains proper joint and spine alignment.
Breathable mattress and accessory materials regulate body temperature and prevent heat buildup to create a cooler sleep experience.
Pressure relief can alleviate aches, stiffness, pain, and sleep apnea by keeping pressure on the mattress consistent across the entire bed.
Elevating the top and/or bottom of your mattress provides targeted support to help reduce snoring, provide pain relief and make reading and watching TV more comfortable.

How long does a mattress last?
Mattresses last an average of 8-10 years.
How do you clean a mattress?
Cleaning a mattress is a simple step-by-step process. First, remove all bedding and covers to wash separately. Then, use the upholstery attachment on your vacuum cleaner to thoroughly vacuum the entire surface of the mattress, paying special attention to seams, crevices and edges. Then, spot-clean stains where needed using different solutions depending on the stain type. Once the mattress is clean, sprinkle a generous layer of baking soda over the surface to deodorize. After a few hours (ideally overnight), vacuum the mattress thoroughly to remove all residue.
