I have had this chair for a month now and the height adjustment has already malfunctioned. Basically it will not hold the desired height level and just bottoms out. Was working fine and I am also well below the max weight limit for the chair. Should have spent more for a better quality chair. Get what you pay for I guess.
We bought this chair after looking at several Possibilities online and then checking with a sales person in the local store who said she had good feedback on it. It is comfortable easy to move from place to place and relatively inexpensive. We are so glad we ordered it from our local store!
