I love this chair! It works smoothly and it’s very comfortable. I have nothing but praise for everything about it.    (This is an update on my review of May 3, 2021. The cushion in the seat is already flattening. It hurts to sit for too long and I’ve had to use a pad in the seat for comfort. I’m an arthritis sufferer and my hips hurt using this chair. I would not recommend this chair to anyone who needs to sit a lot or is heavier than 200lbs. I weigh 225. So far everything else is ok. Will update as needed. I changed my rating from 5 to 3.)
