Help identifying tufted tub chair

[greggregson]

Hi can anyone help me identify this tub/ club chair?

It has a barrel back and tufted/ button fabric upholstery. I’ve seen similar chairs but none with the rounded seat cushion and rolled arms. The arms don’t go all the way around the round seat cushion. The legs are wooden and front legs have casters. I believe this is antique or antique reproduction. I would like help identifying this.
