I have used the mattress. Sometimes I feel like I'm laying on popcorn. The mattress seems to keep the head portion elevated. I sleep on my side so it's not as comfortable to have my head raised. There will come a time as my health decreases that I will need to have my head artificially raised and that I need some degree of constant motion to prevent pressure on my skin. I don't of course look forward to that day but I will be glad I have the mattress to rely upon
Simple to operate and understand with the touch control panel. Although,the audible low pressure alarm is very annoying as it kept beeping with no way of disabling it. Wheelchair Liberty's customer service was very helpful to my needs and concerns. Thanks..
