My wife is 5'9" and I'm 6' the chair's headrest hits both of our shoulders and we had to remove it. We crossed the deadline for return so couldn't return it. Was not expecting this much poor design for the chair which hits people's shoulders and causes you to crunch your shoulders. We removed the head-rest altogether and using the chair without it.
At 5 feet tall finding a chair that I'm able to sit in all the way and have my back supported is nearly impossible. This chair is perfect! I can sit all the way back my legs bend at the knee and reach the floor no dangling no extra pillows. I'm purchasing my 2nd one - one for home one for the office.
