I also cannot get the foot on my dad's stratolounger down. I called the number you listed, but bur after 1 ring, it goes right to a busy signal. I don't know if it really is busy, or if there has been so many calls, they have changed their number.
I'm having a similar problem with my bed. Head is stuck up, foot is stuck down, and the company I bought it from is out of business. And of course, I've been recently injured, and I'm supposed to sleep with my foot above my heart. My feet slide off the pillow in the middle of the night, so that's no help.
I live in Parma, Ohio near Cleveland. Can anybody out there help me?
