Firmly ACA Endorsed
The American Chiropractic Association (ACA) concluded that the mattress’s firm support reduces spinal stress, improves lumbar support, and alleviates back pain
Firmest All-foam Mattress on the Market
Never feel your back dip and never opt for the floor again. The extra firm support (a ten on the firmness scale) will keep you firmly supported all night long
Flippable All-Foam
If your extra firm mattress feels too firm, simply flip the mattress to achieve a medium-firm feel. Flip for firm or firmest—the choice is yours. (Plus, the flippable design improves the longevity of the mattress.)
Time-honored Sleep Design
Our firm design is borrowed from the wisdom of the ancients who slept on firm pads or tatami mats. Our design offers all the benefits of these time-honored traditions while providing a more modern look
High Density Foams
Our foams are thick and dense (and made with the highest quality materials!) to give you firm support while soothing hips and shoulders for long-lasting and restorative sleep
Breathable Materials
Fall sleep and stay asleep with the ideal temperature from foams that sport open cell technology to wick away excess body heat. Breathe easy and deep while enjoying naturally cooling sleep
Perfect Spinal Alignment
Feel aches and pains melt away thanks to the superior spinal alignment found in our oh-so-supportive foam layers. Each foam layer is carefully crafted and placed to give you support where you need it most
