Q: Why am I only being refunded $4 for this textbook when I paid a little over $25? I paid for shipping beforehand, and the tear in the book's cover was not my fault. I received the book exactly like that. The book was not used at all.

Q: Looks good, easy, easy to assemble. Instructions and parts w/ Hex wrench included were shockingly easy to use and assemble. Overall solid parts, arms a little flimsy. Quality overall is very good. Head rest may prove to short even when adjust to it's highest position for people with broad shoulders and 'normal' torso length. Arms not very sturdy, not adjustable (I missed this in the description--my issue). Overall, for the price, will work for the time-being. Comfortable enough, but not a top tier product--quality = pricing so I'm happy.
