Query: good idea, poor execution

I purchased this product with the built in massage for another $100(for a grand total of $199.99)and was so excited to get it because I suffer from disk herniations in my lower back. What a disappointment! I am an average size woman and 5'7" and my feet were hanging off of the end. The cushions are so narrow that your arms end up dangling off of the sides unless you prop more pillows on either side of you. If you don't put pillows beneath your head you end up hyper extending your neck. The massage was a joke, no variable speed and required 8 batteries. SAVE YOUR MONEY!You can buy better pillows to achieve similar results.
