I found the chair easy to assemble and the variable adjustments for height armrests and ability to lean back work very well. Chair is comfortable for fairly long periods of sitting.
Mesh on seat is held together with staples. Within 3 weeks staples were popping and mesh pulled away from seat. Called staples and their return policy with furniture is 14 days. Spend extra and get better quality.
After less than 4 months the seat is falling apart. It is stapled in and with regular use the staples are coming out and one side of the seat is pulling loose. I am very disappointed. It is a comfortable chair. I weigh less than 200 pounds. I do not "drop" down into it. There is no reason for it to be falling apart so soon.
