I went to Staples and sat in every single chair in the store and this one was by far the most comfortable (of all mesh + leather chairs!). I had mine shipped to the store and it arrived on time just a few days later. It only took about 20 minutes to put together and adjust. You can immediately feel the lumbar support. Highly recommend!
I read a lot of reviews before purchasing this chair and they basically said it's great if you're on the shorter size and average weight but not great for larger people. This is basically true. I'm 5'8 175lb Male and this is the PERFECT size chair for me. However I've had friends that were in the 6-foot range and larger find it not as comfortable. There are better chairs to buy if you are larger. The headrest is in the perfect spot for my height and the width is perfect for my weight. I can't speak on shorter people but I will just say if you are an average-sized male in the 5'7-5'9 or maybe 5'10 range this is an amazing chair. Easy to put together and super comfortable and ergonomic. If you are not this size I would look elsewhere.
The headrest angle adjusts but not it’s height - nor does the height of the back adjust. I’m 5’11” and the headrest pokes the tops of my shoulders. The lumbar support adjusts about 1 inch and is still too low for me poking my hips.
