I chose this chair because it has LARGE casters.  I consider that a big plus!
The smaller ones you find on most chairs snag and won't swivel freely.

I would have given this review 5 stars except this was an open box order, and the chair came with missing fasteners.  I had to improvise to securely assemble what was delivered.  The disassembled chair was delivered loose in a large box with the protective padding at the bottom.
