Best decision getting this Helix mattress! I have arthritis in my back and hips. I was sleeping on a new memory foam mattress but still I tossed and turned and woke up in pain. After one week with the Helix Dusk the difference is huge! Pain is gone and I don’t wake up in the night. Awesome product! I also liked that I could try out the mattress at the store before buying. (Yawnder store very helpful).
