Benefits
Pressure Relief
7/10 Good
Pressure relief can alleviate aches, stiffness, pain, and sleep apnea by keeping pressure on the mattress consistent across the entire bed.
Cooling Technology
9/10 Excellent
Temperature-regulating components and materials draw heat away from the body to create a cool and comfortable sleep surface.
Motion Separation
9/10 Excellent
The goal of 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.
Support
9/10 Excellent
Proper support from your mattress 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
Breathable materials regulate body temperature and prevent heat buildup to create a cooler sleep experience.
Craftsmanship
9/10 Excellent
Hand crafted, with a focus on detail, to meet your specific needs ensures our beds and accessories are the highest quality.
Adjustable Base Friendly
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.
