I got this on a good sale and it was relatively easy to put together --- just dealing with the base updside down and attaching the pieces --- begin to thread each screw BEFORE you tighten (as the directions advise) because if you fully tighten one before you thread another one it seems to through off the alignment of the next screw. Comfy chair as I prefer all mesh chairs and I sat on a chair at twice the price in the store and did not notice a difference.
I searched and searched for office chairs and finally found this one for me and my daughter. My daughter is homeschooled so she uses this chair 7 hours a day during the week. She's only 130 pounds and we've only had these chairs for a week or so and the seat part is already wearing down and loosing it's elasticity. This shouldn't be happening within a weeks use. I'm extremely unhappy with these chairs and I'm going to have to purchase another set somewhere else. I do not recommend this chair.
