Description

1. Constructed from high-quality British-standard steel tubing (114 x 55 x 3mm) and high-precision welded pipes, emphasizing a sense of strength and substantiality.
2. Features a one-piece, integrally molded polyurethane foam cushion; the firmness is calibrated to ensure both a stable training trajectory and lasting comfort and durability. Seat, backrest, and round pads are composed of high-density PU foam material and upholstered in 1.2mm-thick, premium-grade 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 of positioning.
4. Manufactured using advanced international production processes—including laser cutting, automated robotic welding, and precision CNC machining—to ensure fabrication meets the highest industry standards.
5. The production process integrates sandblasting for rust removal with electrostatic powder coating. The paint finish involves a multi-stage treatment: immersion-based pre-treatment, full-surface phosphating, and electrostatic powder application. A specialized dual-layer coating process—including a protective glaze finish—is applied to ensure both the aesthetic appeal and corrosion resistance of the equipment.
6. Guide Rods: Ø20mm solid steel guide rods, treated with an anti-corrosion coating and polished to ensure smooth operation and prevent rust. Cables: Utilizes self-lubricating Ø5.8mm steel cables.
7. Targeted Muscle Groups: Primarily targets the quadriceps femoris muscle group. After selecting an appropriate weight, the user extends their legs forward to drive the rotating arm, thereby effectively engaging and exercising the quadriceps.
8. Weight Plates: Constructed entirely from steel.
9. Users can perform all necessary adjustments for their workout while remaining seated in the training position. 
Five adjustable starting positions are available to accommodate the personalized needs of a diverse range of users.
