COOLING HYBRID MATTRESS FOR HOT SLEEPERS – Designed with advanced cooling materials that help draw excess body heat away from the sleep surface for a cooler, more refreshing feel. The breathable hybrid construction combines comfort foams and pocket springs for all-night comfort, available as a Twin mattress, Full mattress, Queen mattress, or King mattress.
5-ZONE SUPPORT FOR BETTER BODY ALIGNMENT – Our 5-zone hybrid mattress delivers targeted support from head to toe, with enhanced support around the shoulders and lumbar area. It helps distribute body weight more evenly, relieve pressure points, and promote natural spinal alignment for more comfortable sleep.
PRESSURE RELIEF + RESPONSIVE POCKET SPRINGS – Comfort foams gently cushion your shoulders, back, and hips while individually wrapped coils provide responsive support underneath. This pocket spring mattress offers a balanced combination of pressure relief and support without excessive sinking.
MOTION ISOLATION FOR UNDISTURBED SLEEP – Individually wrapped pocket coils move independently to help reduce motion transfer, so you’re less likely to feel your partner tossing and turning. A great cooling mattress for couples, combination sleepers, and anyone looking for a supportive mattress in a box.
10, 12 & 14 INCH OPTIONS + 365-NIGHT TRIAL – Choose from 10-inch, 12 inch, or 14 inch mattress profiles in Twin, Full, Queen, and King sizes to fit your sleep space and comfort needs. Every SLEEP100 fiberglass-free mattress includes a 365-night home trial and warranty for greater peace of mind.
Customers find the mattress extremely firm and comfortable, with one noting it took only two nights to get used to it. Moreover, they report improved sleep quality, waking up feeling rested, and significant relief from back pain. The mattress receives positive feedback for its edge support and value for money, with one customer mentioning it saved thousands compared to brand-name alternatives. However, opinions about fit are mixed, with some saying it’s a great match for their bed frame while others report it doesn’t stay in place.
