Advanced Wooden Top Stool The design of this stool allows it to be lifted with ease via the useful hand hole on the top of the wooden seat. The 22mm diameter four legged steel frames are coated in Epoxy powder coat finish to give maximum life. A 19mm diameter bracing-bar has also been added to give extra strength to the high frame. We supply a wide range of tops with or without hand holes. Our tops come in 18mm ply or laminated MDF with a clear lacquered edge.
