This chair arrived twice in boxes that had opened and parts had fallen out. The second time, the UPS driver gave me  what had fallen out. They need to package better.
The chair also tilts at the base, but the back does not tilt away from the base. My son tried too hard to tilt and it cracked the chair. Totally his fault but I was surprised it was so easy to break (he is 6' tall). Use caution when tilting or with larger users.
Otherwise, good chair for the money. The company was great about dealing with the delivery issues. 

Pros: Comfortable, price
Cons: Not super durable; poor packaging
