This is a great chair, comfortable, great support, easy to adjust, and great condition.
I am there original owner, and am selling it because I inherited a leather desk chair with is not as comfortable, but since retired, I don't sit at the computer as much and the new chair matched my office furniture.
Features and dimension can be found online.
I bought it at Staples and it retails for $400.00.
It is 28" Wide arm rest to arm rest.
25" Deep and 432" Height
The right arm rest was misplaced during a move but can be purchased one through Tempur-pedic.
