Update: seller shipped replacement part and chair is now functional. My son loves it.The base had an extra bit of metal where it was welded, which does not permit screw alignment for leg assembly. Emailed manufacturer (their phone # was not accepting calls). They were initially responsive, advising they would send a replacement part and tracking info ASAP. It’s been a few days and nothing further. Hoping to avoid having to pack up and send the whole thing back for a new one. Mesh on chair back seems a bit flimsy, hoping it will stand up to my 10-year-old’s use. Love the blue color.I bought this chair for my standing desk because it seemed very tall on the pictures. Assembling it took me 2 hours just to realize that this wasn't a fit for my desk. I returned it. But for a regular desk I think it was an okay chair.The product came packaged well, all parts including extra bolts. Easy to follow instructions and assembled within 20 minutes. The product looks nice. Height adjustment is easy. It just doesn’t roll as well as other chairs. I’m 200lbs, and the wheels have trouble orienting the right way to roll. This would be used by my kids so I don’t see any issue.The thing I like most about the chair is that it is not as big and bulky as some others. There is excellent lumbar support which is the main thing I look for in a desk chair. The seat cushion and back support are perfect with the right amount of cushioning. Happy with my purchase.Seat fabric looks to be durable. Arm supports fit nicely under the desk. Overall works well for me. Assembly was not difficult other than lining up back to get screws in which was tricky.I like it overall (just bought it). 4 stars because I am worried that the mesh is a bit weak and might break. But I will wait for a couple of months and revisit.It’s good for the price! Easy to assemble!I get so many compliments on my chair, and it fits in perfect with my style.
