As to the "Sleep Number Beds" I do think that ditching Rush will really slash their market as Rush was often giving them to people so much that others, like myself, became fascinated with what their selling points really were.
Unfortunately, any mattress that needed to send me a video so that I might find out what they actually were selling for, surpassed my cash flow, though my hubby did by me some Bose headphones and they're the greatest (on a recent trip, he snoring away and I left with nowhere else to lay my head, snapped on my "noise cancelling" Bose, slept soundly!)
We bought a sleep number bed years ago, back before they even started putting numbers on the controls. - First night I slept on it, my back woke up rested. So far, we’ve been able to just replace the innards when husband’s side of it goes kaplunk.
It has been great - and economical. We were replacing conventional mattresses every few months before we got the sleep number (before they were putting numbers on them).
I’d recommend getting a thick mattress pad for it if you get one; just works better to my way of thinking.
