I have a question regarding the relationship between PD and choosing the right bed. Are there any "PD Friendly Beds"? We recently tried an expensive king size Serta pillow-top bed. My wife loved it but I had trouble moving around at night. The extra padding seems to be more restrictive than my old bed. I was wondering if anybody else has had experiences like this or is it just my imagination. Are there any beds or features that are, in general, more comfortable for people with PD? Help. Looking forward to your advice. PS - Anybody tried the Simmons (do not disturb) bed? Do pillow tops make any difference?
