The quality of the chair leaves a lot to be desired. Couple of issues we faced: 1. The screw holes in the arms were not aligned causing an imperfect assembly. 2. The lock / free lever doesn't function as designed. The chair still leans back after locking it in position. 3. The length of screws provided for the assembly was not designed keeping the ease of assembly in mind. For joints on the arms and backrest the holes provided were way inwards making it difficult to put the screws in place and assemble.
My son loves his new chair. It took us about 30 minutes to put together. Everything needed was included. It's comfortable and good lower back support. Armrests are comfortable too.
Love the height of the back side of the chair and the material the chair is made out of but padding distribution is uncomfortable and the chair itself is wobbly (tried it on different surfaces).
