Purchased the stool for guitar practice. Assembly consists of bolting the legs to the seat and bolting a steel ring to the legs. All bolts were left loose and a 75# weight was placed on the seat, prior to tightening. Try as I might, I could not remove the wobble of the completed stool. Rather than return the stool, I am considering grinding off 1/8" from one leg to resolve the issue. I believe the stool will serve its purpose, but it is a bit pricy given the quality of the design.
