text: I was very excited and optimistic about this product! When first trying it, it was very comfortable but I wished it could be a little taller. I used it for a couple months at work and the seat started the slowly lower while sitting. I contacted the manufacturer directly and the customer was great. They sent me a replacement part and I was satisfied. Until about 2 months later and it is having the same problem. Contacted them again, they sent another replacement part but this one for some reason or another won’t raise as high as the others had. When contacted again, the customer service rep let me know that it could take a month to get a new part shipped from overseas. I like this product but am disappointed with the quality.
