I’ve been sleeping in my ReST Split King now for 1 year and it’s by far the best bed I’ve ever slept in. Prior to buying my ReST bed last year, I had a king Sleep Number for about 10 years. I was going to buy another Sleep Number until I did some research and found ReST. For me, the ReST bed is superior in terms of both comfort and how I feel when I get out of bed. I’m 57 years old and if the bed isn’t comfortable to me, I wake up feeling like I’m 77 years old. Let’s just say that when I get out of bed in the morning after sleeping in my ReST bed, I honestly feel like I did when I was 37!
