I bought this to replace another office chair that was not so comfortable. This chair has been wonderful for me comfortable and slides easily around my office.
I was debating about whether to pay Staples $20 for assembly and decided to try it myself. Easiest assembly you could ask for; all of the parts are clearly labeled all of the screws and other parts were actually in the box and the only tool you will need is an Allen wrench which they include. Direction booklet is very straightforward and easy to understand. Total assembly time including unpacking and reading the instruction booklet is under 30 minutes (and I'm an octogenarian). You do need a little arm and wrist strength but if I can do it I think anyone can. My advice is to sit the seat cushion on a 12-15" table so you have room to attach the arms etc. Can't comment on the durability of this product since I just got it but wanted to comment on the favorable assembly experience.
