Temperature-regulating components and materials draw heat away from the body to create a cool and comfortable sleep surface.

Cooling Technology

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.

Motion Separation

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.

Support

Breathable mattress and accessory materials regulate body temperature and prevent heat buildup to create a cooler sleep experience.

Breathable

Pressure relief can alleviate aches, stiffness, pain, and sleep apnea by keeping pressure on the mattress consistent across the entire bed.

Pressure Relief

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.
