I've had mine for several years and it works like brand new. It also tri-folds if I only need a smaller coverage area. The cover is super easy to take off and put back on. I just hand wash and hang it over my sink to dry before heading out to work, and it's dry and ready to put back on by the time I get home. I have chronic neck and back inflammation issues, and this mammoth provides full coverage! I turned my Airrosti doc onto them as well! Give it a try; I know you'll love yours ALMOST as much as I love mine! Pic with dental floss to show size. If I could attach this to my body, I'd be Ice Wrapped all over! Lol (ps the Clay makes it last so much longer!)
