I purchased this chair after going to my local staples and trying out every chair they had on the floor. I was looking for a chair that has adjustable lumbar support with a high back. Being 6'0 the back of the chair comes right to the top of my back (perfect). Another characteristic of an office chair what adjustable arms. This has the perfect height I needed/wanted for my work station. I sit in this chair for about 5-6 hours a day. Very comfortable seat cushion too! I give it 5 stars because it was exactly what I was looking for and the price was affordable!
