For years I have had issues with my arms going to “sleep” at night, and causing me to wake up many times through the night in pain. When shopping for a new bed I did a lot of research and was very interested in the ReST bed. In n the store I actually laughed for several minutes on other mattresses top test them out, and had issues with my arms. I then tried the ReST bed and never had any issues. We have had our new bed for almost 2 months, and I have never slept better! Automatic mode is amazing! It adjusts throughout the night top keep the pressure where I want it. The only downfall I see so far with the bed is that it does not cool down, and hold heat. The adjustable base makes this the perfect bed!
