I have never been so dissapointed by a product on Wayfair's site. I purchased two of these chairs- one last year and this one Dec. 2018. The old one is great and I still use it. This one is defective and now I cannot return because its outside of return window. The seat cushion is COMPLETELY deflated after less than a week of modest use. I was looking forward to having this as my new office chair but it is just too painful
