With this work-at-home becoming a longer-term ordeal than I had anticipated, I knew I would need to get a new chair to replace the one I had been using (it was old and did not have good back support). I received this chair the other day, and my husband put it together in no time. Wow ~ it has surpassed my expectations. Since I started using it (and my days are typically 8-10 hour days), my back has felt so much better. It conforms to my body perfectly. Best decision ever to purchase this chair!
