I would just like to say that it has been a pleasure dealing with Lloyd at ReST, he has been very responsive to any questions we had. We received our ReST bed earlier this week, my wife has been dealing with back issues from a car accident years ago. We had decided on this bed as an opportunity had come up. We are not disappointed, this bed is just fantastic!! Each zone can be adjusted to firmness or softness and can self adjust when needed. I am happy to say sleeping and getting a good nights sleep is now achievable. Thanks ReST for a great product!!
