Purchased one chair from Wayfair, assembled it easily, was so impressed with it that we bought a second one for my husband's computer desk as well.  Once the assembling instructions were read and followed it was simple to create.  Casters were all in perfect condition on arrival and the chair can roll on our carpet.  I like that even at it's lowest chair height it is comfortable for my knees.  Each Banker's chair looks and feels strong and is a nice, smoothly finished piece of furniture.
