Here are the pros and cons.  The massage and heat features are nice, but 15 minutes is not long enough (at times) before it shuts itself off due to the possibility of overheating.  The sturdiness and support of the chair is great. However, it doesn't always sit flat on the couch or bed without a little maneuvering.  Zipping the arms on and off is not worth the headache of storage.  If you can't leave the arms on, I would not buy this.  It's just a hassle.  Overall, I do like it, but it's definitely not a 5 star product to me.
