This chair appears to be very well made. I bought it for my teenage daughter. The casters took a little effort to put on but other than that it went together fairly easy. A little concerned about the mesh on the seat back and if it will hold up long-term but hopefully it will.
The chair is a good value for the money. An equally wonderful thing are the instructions. They are so clear and easy and helpful that my husband and I will look for an Essentials product first when we need something.
Does the job at the price -- not super comfortable for long periods of time. Used for 8-5 work on computer. Probably better for shorter time frames i.e. sewing crafts occasional office work etc.
Once I got the wheels in place the rest was easy. The fit was so tight I ended up rubbing a hard wax on the shafts to get them to seat properly. If not for that I would have given five stars.
