Our coach came with a king Sleep Number bed. What a piece of JUNK! Sleep Number replaced the motor and wands once under warranty. After the warranty expired at 3 yrs., the right side started losing air and would go completely flat, the left side stayed full.
The sleep number wands stopped working soon after the replacements came. The pump part worked, you just couldn't see the numbers.
Anyway, near St. Louis, we had enough. We went to a mattress store and bought an eastern full size king Beauty Rest pillow-top mattress. The piece of JUNK sleep number went into the dumpster.
It was a bit difficult getting the mattress in but it made and we love it. I will never have another 'automatic' mattress again.
Other have had good luck, we didn't.
