Dial-a-Bed Exceptional Poor Customer Service

The sales staff hugely promoted the \100 night trial and return offer if you don't absolutely love it". After about 3-weeks my mother informed me that the bed is not comfortable (too hard) and that she would like to exchange it for a softer option. I tried calling the store"
