We got the split king with adjustable frame and we both love the beds with our personal settings. Five zones, pressure sensing and smart adjustment, modular design, great app, fantastic warranty, etc. the list goes on. The most advertise competition doesn’t even come close with 1 chamber/zone like a camping mattress. The ReST has five chambers/zones to allow you to set pressure for the different parts of your body regardless of being a back, side, or stomach sleeper. The pressure sensor helps you tune it to your liking and the app allows great granularity. I really like that the bed is modular so if something does go wrong, you swap it out or if you do not like the ‘topper’ you can put something else in which my wife did. A great warranty was a plus. Customer service is one of the best I have ever worked with too. They helped trouble shoot a connectivity issue and then sent me a replacement part overnight. They also listened to my suggestions and in the next app update, my suggestions were in there. I tell all my friends to look at a ReST bed.
