The chair comes boxed with five parts: a five wheeled base and rollers an adjustable height shaft a seat a back and two adjustable arm rests. An instruction pamphlet is included. Assembly is done using a dozen bolts and a supplied Allen wrench. No other tool is needed. For a dunce like me an hour is sufficient to achieve full assembly; some one more mechanically inclined might find a half hour generous time. The chair has a solid feel to it.
I am very dissatisfied with the traymore luxura managers chair. The seat padding has permanently flattened and the cushion is so uncomfortable it cannot be used for more than one hour at a time. It causes significant back pain and leg pain. I would like to return it as a defective product as I have owned it for less than 30 days
