Wish I did. But no. My bed is too soft for me in the first place, so I’m about ready to put it on freecycle and sleep on the floor for a while.
A bed buddy would be nice for backrubs, too. And that thingy you showed me...what did you say it was?
;o]
They have them at Wal-Mart. You pop them in the microwave for 2-3 minutes and you have nice warm moist heat for at least 2 hours. That and wintergreen oil has helped me through a lot of back aches.
