Ordered Olive green but chair looks like more of a light grey to me.  Not sure the wrong colour chair was sent.  Chair otherwise is very stylish and comfortable to sit in.  It was also very quick and easy for my Brother In Law to put together, those are plusses.  My only other real complaint is chair is very hard to roll, castors are not the best.  I even have it on a chair mat and it’s still hard rolling. Since I like chair and hate going through any process of returning is there a better castor set anyone would recommend comparable and easy to replace ones on this chair  Rolling is kind of important to me.  Thanks.
