The king size Sleep Number bed that came with our new 2008 Dynasty was a piece of junk. After warranty replacements for the pump and wands, it failed again.
It found it's way to a dumpster outside St. Louis and we went down to the local mattress store and bought a king Beauty Rest pillow top mattress! HEAVEN!
The REAL mattress that was so comfortable that when I sold the Dyansty, I bought a regular RV mattress for it so the new owners would have a new mattress and the Beauty Rest replaced one of the Stick and Brick mattresses. Love that mattress!
I will never have any type of mattress that has a pump, electronics or an electric plug.... NEVER!
Safe travels,
MM.
