Office Chair

This is a very heavy oak and iron swival office chair. It is patented and adjustable. I believe it was made in and around the 1920s. There is a number in the back side of it as you can see from the pictures, 856. There is also a tag on the bottom which reads as follows: P. Derby and Company; Gardner Chairs Mass; Earl Thompson Posture Seat; Patented Patents Pending
