I suffer from Fibromyalgia and have had 2 ACL replacements on my left knee. This bed is no cure but it has greatly improved my life. I sleep better and longer. I fall asleep quicker. I wake up with less pain and stiffness. I no longer want to travel overnight as that would leave me without all the comforts of my new bed. I sometimes go back to bed in middle of day to relieve pain and discomfort, thirty mins brings refreshes me so I can get through the rest of my day.
