I have arthritis in low back and struggled to find the most comfortable mattress. We vacationed in the fall and the vacation rental had THE MOST COMFORTABLE mattress I have ever slept on. I couldn’t wait to go to bed!  I contacted the owner and got the exact info and it was this one!  She said every guest asks what this mattress is because it is so comfortable.  Now I have my own and we bought our sister and brother in law one!!  The best mattress ever and Wayfair is my favorite shopping site as they have great products at good prices and are super to deal with!!
