Finished! Major props to Riley Eckman for designing these with me. These stools are made of tractor seats mounted to suspension springs from a Dodge 3/4 ton 4x4 pickup which is mounted to 15" trailer rims. All welded together with hook anchors from a vintage truck jack handle. After this pic was taken, I lined the sharp edges of the rims with grey dishwasher hose (ends held together with grey Gorilla glue) so that the edges won't cut bare feet or scratch the floor. FABULOUS!
