I bought a bundle which included the blanket. It is the best thing I ever did regarding my health. I have an extremely arthritic leg, even after a night’s sleep it is so stiff, sore, feels like glass and it is going to shatter as soon as I move it!! Unbelievably the first night using this I got up out of bed no problem, and consequently since then, this has been a week now and I haven’t had to take any tablets for the pain. I can’t imagine it is a coincedence!
