The legs (or spokes or whatever they are called) are extremely sharp and I have cut my ankles on them 3 times in the week I have had this chair.  
Also, I have the setting on the loosest but it is still hard to recline.  
Very uncomfortable chair!!!

UPDATE:   I would like to commend the customer service staff for the way they handled this.  They bent over backwards to make sure I was satisfied.  Because of this I'm changing from one star to 3 stars.
