Professor Ergo's Thoughts:
The Office Master YS series of chairs are great and adjustable ergonomic chairs with flexible mesh backs. The Office Master Yes Mesh YS84 Mid Back Task Chair is one of my favorites of the line because it offers a number of adjustable features plus a seat slider and a tilt tension knob. These adjustments help you fit the chair to your body and working style, plus they make sure you're always comfortable in the chair.

Our Customers Say ...
I received the chairs today and they are perfect. Thank you for your personal attention to my shipping snafu. In this day and age of the internet and push button instant gratification, we sometimes forget that the real value is not in a price that is 1% better. It's in the value added by empathetic people who really try to help. Maybe you should create a company tag line like "Real humans providing great human solutions."
