This is my first purchase from wafair; I tried to love this chair but good god it has given me more grief than anything. I installed everything as it said. It doesn't adjust height as it's supposed to and it's incredibly squeaky anytime I move. I took the chair part off the base/pole to see if I could solve the squeaking but then ended up extending the part that it rests on all the way up- now I can't get it down where it was. Also upon inspecting the inside there seems to be something weird. So now I have it stuck in highest position and I'm out $170. I just purchased the chair in February, so it’s about 2 months old.
