Description

1. Constructed from high-quality British-standard steel tubing (114x55x3mm) and high-precision welded pipes, emphasizing a sense of strength and substantiality.
2. Features a one-piece, integrally molded polyurethane foam cushion; the firmness level ensures both a stable training trajectory and exceptional comfort and durability. Seat, backrest, and round cushions are composed of high-density PU foam and upholstered in premium 1.2mm-thick leather, available in a variety of colors.
3. The seat adjustment mechanism utilizes a rubber-cradle locking system, offering a convenient, rapid, and highly secure method for positioning.
4. Manufactured using advanced international production processes—including laser cutting, automated robotic welding, and precision CNC machining—to ensure tooling operations meet the highest industry standards.
5. The rust-removal sandblasting and electrostatic spraying processes work in tandem with a sophisticated baking paint finish. This finish involves an immersion-based pre-treatment, full-surface phosphating, and electrostatic powder coating. A unique dual-layer coating process—including a protective glaze layer—is applied to ensure both the aesthetic appeal and corrosion resistance of the equipment.
6. Guide Rods: φ20mm solid steel guide rods, treated with an anti-corrosion coating and polished to ensure smooth operation and prevent rust. Cables: Utilize self-lubricating φ5.8mm steel cables.
7. Targeted Training Area: Back.
8. Weight Plates: Constructed entirely from steel.
9. Features five distinct starting positions to accommodate the varying needs of different users regarding training range of motion and body positioning. 
Dual-position non-slip foot support bars allow users of various body types to perform exercises effectively.
A lumbar support pad ensures that the user maintains a correct, neutral spinal alignment throughout the workout.
