I have a couple bulged discs in my back and arthritis in my hips and have struggled to find a mattress that worked for both me and my husband. The ReST bed is phenomenal for sleeping. I have way less restless sleeping and wake up in less pain. I’m hopeful that the app will be improved upon. Sometimes it works, sometimes it doesn’t. The setup was a bit of a challenge but someone with tech support was great to help us out.
