About Soma Organic 11 Mattress

The Soma Organic 11 Mattress is the third mattress is Soma’s own series of mattresses. Made by the Obasan factory based in Ottawa, the Soma Organic 11 offers a medium-soft to medium-firm comfort range. This mattress is an excellent option for various sleep positions. The Soma Organic 11 has a 4 + 4 + 3 combination and allows for four distinct feels. This mattress offers the unique opportunity to not only have differing core layers on each side, but also the ability to customize the surface layer comfort in either Soft or Medium density. Having a split top layer provides couples the chance to really customize their side of the mattress to fit their exact sleep needs without compromise. Additionally, it helps reduce transfer of motion at the surface level. Looking for a little less customization, or a little less softness in your mattress? The Soma Organic 9 mattress still provides side-to-side customization with two solid comfort levels.

All Soma Organic 11 Mattresses are Made in Canada.
