UNIQUE DESIGN: Built on human motion mechanics, the stool heights available from the ground are 9.1 inches, 12.6 inches, and 15.7 inches. The stool has a diameter of 11.2 inches and a maximum capacity of 450 pounds. CONVENIENT AND PRACTICAL: When you need to squat or kneel, sitting on a low stool helps protect knee joints and lower limbs. This is especially beneficial for people with joint pain or varicose veins. The roller stool features wheels that let you move while seated, so you do not have to stand up to relocate. FLEXIBLE AND COMFORTABLE: The waterproof leather cushion features a memory function and quickly returns to its original shape after weight is removed. The cushion adjusts to body weight, providing support for prolonged seating and helping protect skin and muscle tissue of the buttocks. DURABLE UNIVERSAL SWIVEL CASTER WHEELS: 360 degree swiveling, with ring steel balls for smooth rotation. The wheels are impact resistant, shock absorbing, and wear resistant. They roll on thin carpet or moderately rough concrete, offering durability and reduced wear. USE SCENARIOS: In a workshop or garage for tool assembly, maintenance, or painting, allowing you to reach work areas without constant standing and repositioning. In the kitchen for cooking, cleaning, and overhead tasks, enabling easy access to different stations while seated. In crafts, electronics work, or automotive maintenance, where you need to sit and glide to different spots without interrupting your workflow.
