Hello, we've got a super king Sapphire 12700 Harrison bed and we hate it (it's only 1 yr ok'd). One side is soft and the other is medium. I'm about 5'5 136lbs and my hubby is 5'6 145 lbs. My husband finds the medium side good but I can't sleep on either side. The soft side is too soft and doesn't offer enough support to my lower back and hips while the medium side is great for my back but too hard for my shoulders and causing me pain. I can live with the shoulder pain but not the back pain so I choose to sleep on the medium side. My husband unfortunately now has to sleep on the soft side and he hates it! Now he has the back pain. We are both side sleepers/back sleepers and are desperate to get a decent nights rest without pain. We spent a fortune on this awful mattress so are scared that history may repeat itself and nervous customers. Please, what would you recommend for us based on the information given. We are open to all bed types. Thanking you in advance.
