In addition to personal preference, consider the size of your bedroom, who you’ll be sharing your bed with and available space. Use our guide to gauge the dimensions of all four standard SONU mattress sizes to help you choose the best one for your needs.
Every SONU’s height is 14 inches, while the width and length dimensions are the same as standard U.S. mattress sizes. The Comfort Channel dimensions below describe the negative space in the mattress, while the Support Pillow dimensions describe a single pillow, of the 2 for Twin XL and 4 for Queen, King and Cali King, that are stacked in the Channel.

Relief nationwide.
★★★★★Game changer
I tried many remedies but none solved my problem until I discovered the Sonu mattress with the cut out arm channels. This has become a game changer. No more shoulder pain, no more dead arms, and the most comfortable sleep I have had in years.
Christopher G.Verified ShopperFloral Park, NY
★★★★★Finally sleeping again!
As someone with frozen shoulder in one arm and having had surgery on the other due to frozen shoulder, sleep was fleeting. I hadn't slept well for about 2 yrs until I got this mattress. It has been life changing for me!
Jessica F.Verified ShopperJohns Island, SC
★★★★★Finally!
For 40 years I have wanted a bed with "a hole in it for my arm". Better than a hole is this design. No more pain or numbness plus it is gentler on my hip bone and better for my lower back.
Gregory O.Verified ShopperParkville, MD
★★★★★Fantastic!
I had just about given up on thoughts of sleeping through the night ever again. I would wake up 30 to 40 times a night to adjust myself. I can't begin to explain what it feels like to sleep through an entire night.
Crystal G.Verified ShopperNew Palest., IN
★★★★★Relief from shoulder and neck pain
I'd wake up multiple times a night because of my arm falling asleep or pressure on my hips, and then wake up with terrible neck pain. I wake much less frequently in the night, and I have no pain in the mornings!
Amy Y.Verified ShopperSparks, NV
★★★★★Life changing
After two rotator cuff surgeries over the last 5 years I haven't been able to get a good night sleep. I was nervous about the big investment, but I'm glad I did and would recommend to anyone with shoulder problems.
