The main frame is built with 75×75×3 mm standard square tubing . It features a vertical storage design (with bottom padding to ensure stability and protect the floor). The seat and backrest use standard anti-slip leather covering polyurethane foam padding , which is several times more durable than traditional compressed foam. Both the front and rear use an anti-slip tooth-style adjustment design , combined with an efficient bolt-locking mechanism .
