It's basically a good chair. It tilts forward a little and the padding isn't fantastic hence the 4 stars. That said it does the job and the ability to raise the arm rests is a big plus.
This is a great looking chair easy to assemble but there was a lean to it towards the left. I thought it would work itself out over time but after a week I returned it. The rotating armrests are a great feature rolls smooth firm but comfortable seating area. Just couldn't get over the lean.
