After going through a bed in a box a year I decided I needed to buy a quality mattress. I spent weeks researching into several different brands: Dream Cloud, Nectar, Sleep Number, Purple, etc. I decided I wanted a sleep number or a purple. After some more google skills I found REST. Best decision so far. Back pain is gone. I purchased Purple sheets and pillows and my wrists/hands no longer are numb. This is a game changer. Pricey yes, worth it, yes.
