This chair is great except for the headrest. It comes out too far from the chair. The depth of the seat is comfortable for a short person: 5'2. I will be returning for the other chair that looks identical to this one which I sat in at the store. I bought the wrong one because the right one was in the wrong spot.
I like my first one, and it lasted a bit more than three years. They improved the back locking mechanism- it seems (I've only had the new one for hours now). BUT- the back's most upright position is too far forward, and the seat feels like the front is too high and the back of the seat is too low. So it puts a lot of pressure on your under-thigh behind the knee, and it feels like your knees are being pushed up into the abdomen. I write this in January, 2026. I have it adjusted as low as it will go, and it doesn't go as low as the one I had for just over three years. So my keyboard drawer just clears my knees and sits atop my squished thighs. I don't believe I will be able to get used to this. It's not comfortable for office use.
