The chair is the best chair I've ever sat in, I'm 6 foot 5 so finding a nice chair is very hard for me. The assembly was a breeze, and everything went together nicely. One of the bolts was rounded out but other than that it went nicely. The one flaw is the wheelbase is really short and it tips so easily even when sitting normally any sharp movement will make it tip. It renders the footrest unusable unless you're on carpet and you lower the seat all the way down. All in all im not dis satisfied but I hope in the future when I buy another one of these chairs that the wheelbase is a little safer. I'd also like to mention that this chair is really supportive and definitely worth the money if you're careful sitting in it. I bought a wheelbase with one more lag and wheel so hopefully it solves the tipping issue. I've seen lots of reviews on Amazon of this chair being squeaky out of the box. If you assemble it correctly and evenly its really smooth.
