1. Tubing Specifications: The main frame utilizes a combination of high-strength circular steel tubing (φ95mm x 2.5mm) and high-strength rectangular steel tubing (50mm x 100mm x 2.5mm). 2. Upholstery: The product features a one-piece, integrally molded polyurethane foam seat cushion. Its firmness is calibrated to ensure both a stable training trajectory and exceptional comfort and durability. The seat, backrest, and round pads are constructed from high-density PU foam material and covered with premium 1.2mm-thick leather; a variety of color options are available. 3. Manufacturing Process: Production employs high-end international manufacturing techniques—including laser cutting, automated robotic welding, and precision CNC machining—to achieve state-of-the-art standards in tooling and fabrication. 4. Surface Treatment: The sandblasting rust-removal process and electrostatic spraying process work in tandem. The paint finish involves an immersion-based pre-treatment process, full-surface phosphating, and electrostatic powder coating. A specialized dual-layer coating process—including a protective glaze layer—is applied to ensure both the aesthetic appeal and corrosion resistance of the equipment. 5. Total Machine Weight: 196 kg. 6. Safety Stops: The equipment is fitted with safety limit posts on both sides; the adjustment handles for these limit posts are positioned within easy reach of the user. 7. Targeted Muscle Groups: Posterior thigh muscles (hamstrings) and gluteal muscles.
