Got this for my son but used it myself a bit too. Easy to assemble though takes 20 minutes or so. Had this for one week and it seems solid and sturdy. Good height adjustment wide range. The back does not adjust up/down. Will order another for my daughter.
I was using a simple fold up chair before and this is a significant improvement. It's comfortable to sit in for long periods of time. Sturdy and function. Importantly it has two essential features: height adjustment and adjustable arm rests. I've had improper ergonomics for a while which led to "mouse shoulder" in my left arm to the point I was injured and could barely lift my arm. It was starting to creep into my right arm too (I switched from mousing with my left to right). Being able to rest my arm on the arm rests has really helped. I didn't realize how much weight your arms have and how much stress that can put on your shoulders. Delivery was also fast helpful since I don't own a car. Overall would highly recommend if you need a chair upgrade.
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
