The chair is wonderful. I was able to adjust it to fit very easily. The only thing that annoyed me was my shopping experience. I wasn't offered the purchase online deliver to the store for assembly on tax free Sunday. I needed a chair so went back on Monday to review my options. That is when the online purchase was suggested. The first chair came to the store damaged and I had to wait an additional day. So I paid extra for tax and had to wait after my promised delivery date - the store didn't offer anything to offset my additional cost and aggravation.
I used a Herman Miller Aeron at work and this definitely isn't that. The lumbar support isn't as good (it doesn't go high enough) but a towel shoved into the top seems to help. At the lowest point the arms are at least an inch higher so I didn't put them on. I'll probably get a pad to protect the floor; the wheels are better suited for carpet. The headrest is nice. I'm 5'7 and the height is okay for me though I agree that it would be nicer if it were adjustable. I do like the color a lot.
Chair is very comfortable but I’ve heard Staples chairs don’t last as long as other brands. The price was good for the features so I decided to take a chance and have been happy thus far. Right now the rating is 5 stars and will remain that way if it lasts.
