I really hate that they do this. I had a friend who also got stuck with the same situation and did not have a good experience as a result. They should send you home to try the top-of-the-line model and then let you duke it out with your insurance company! ;)

Speaking side-sleeping, I have sewn a sock with a tennis ball to the back of my sleeping tshirt. It worked well, but it's hard to wash. So I bought this contraption: https://www.amazon.com/stream/ref=nav_upnav_mobile_T2_Detail...

Side-sleeping is a big deal, but it's even better with a neck pillow.
