I was given this for my shop. I have never seen a stool like this one before so I thought I would post it and see if anyone else has seen on and might know what it was used for besides sitting on. It needs some cleaning up but it is really nice and solid plus it is heavey so it won't tip over to easily. The seat can be reaised by pulling up on a lever just under the seat and lifting. It will raise about twelve inches.
