Try Happsy. They work with you!
I have the mattress topper and the mattress. I like it better with the topper as it makes the bed less firm, but if you like firm then you might not need the topper. I was struggling with hip pain when I sleep and I'm only in my 30's. We decided to upgrade our "regular" queen sized mattress to a more comfy mattress in the king-size. We did get another online brand mattress but shortly after I began researching how toxic memory foam is, plus the off gassing was unbearable with my allergies. I couldn't bring myself to sleep on that other new online, "sent in the box" mattress we had just bought from another brand, and so we returned it immediately. I stumbled upon Happsy and was literally so HAPPY and the customer service from Dale was OUTSTANDING!!!
