Best of the best mattress!

I am glad i bought 2 single mattress, It really help my back and neck problem. I used it since Aug. 2017 within 2 weeks to now i can get up straight and touch my toes i can't do that before. now i can turn my neck left and right up and down swiftly, be i must ture slowly. I am really surprise this mattress really works. i don't used my massager for my back and neck.
