This chair was great for about two days until my mid lower back began to ache. I think the seat has a bit too much give and allows the pressure to gather at that point. I returned the chair. Kudos to Staples for a smooth return.
Chair is of good quality! However if your big person would recommend a different chair. I’m only 6ft and weigh 210 and the chair is not the best fit for someone my size or larger!
