Ergonomic Wide Seat Design: Rectangular shape (19" width) prioritizes hip and posture support during long hours—ideal for salon work, lab tasks, or medical settings. Soft yet supportive cushion retains shape without sagging Stable Anti-Slip Safety System: Curved leather seat centers your weight and locks securely, paired with reinforced chrome base (not nylon) to prevent tipping. Fits users needing extra stability during recovery or mobility challenges Silent Rolling Stool with Dual Brakes: Quiet scratch-free rubber wheels glide smoothly on tile, carpet, or hardwood, while dual locks secure positions instantly. Essential for physicians, or tattoo artists where stability is critical Extended Height Range (24"-31") for Versatility: Perfect for lab technicians, veterinary exams, or adjustable standing desks. Ensures full-body support during clinical tasks, school classroom teaching, or studio workstations Heavy-Duty Multi-Scene Use: Industrial-grade metal frame supports 330 lbs. Built-in footrest eliminates dangling during long shifts at nail studios, hospitals, libraries, massage tables, or veterinary clinics IMPORTANT: If you need a counter height stool but at the lowest (24’’-31’’), recommend the SHORTER stool (19’’-24’’). Otherwise your feet won't touch the floor and can't roll around In the process of selling small round stool, we often receive feedback from customers that the cushion is too small. However, the diameter of our small round stool cushion is 15 inches, which is 1-2 inches larger than similar products in the market. We are very upset. Finally we found a new solution: we changed the circle into a rectangle, like a chair cushion. We kept researching, refining, and now it's here for you.
