I read through the reviews to get a good sense of the product and would like to address both the good and the bad. The good it’s comfortable for long sitting spells. I bought this as an alternative to the herman miller aeron chair and I can say I’m glad I did. It’s solid and I could buy three of these for the price of one of the herman miller chairs. The bad reviews focused on staples holding the material coming out and the difficulty of assembling yourself. There’s no 100% foolproof manufacturing process the real test is whether they were able to get it replaced without hassle. Read the reviews with that in mind. Also the manual is all pictures with no wording. If you take it step by step and slow it’s not a problem. A couple of times I looked multiple times to make sure but it went together rock solid. Love it will get again even if it wears out in a reasonable time.
