This is an awesome chair. In "Bossman's '" review, he could not get his to rock, but I assure it does. All "executive" chairs with the five "leg" base will swivel, tilt, rock ,as well as lock upright without tilting. It is just a matter of learning all of the functions. I had my last chair like this one for twelve years. It still had all of it's functions, but it had some nicks from bumping the desk and had been through a few moves. It took less than a week to arrive and was well packaged. It took one female less than 15 minutes to assemble, using my cordless drill. Assemble your screws just a bit at a time before tightening and they will line up. The quality of the leather is nice. This chair is the quality of several I looked at, that were 2-3 times this price.
