The Original Frontier XL Configuration

The manufacturer’s Japanese store identifies the black XL configuration as AD12YXL-17-B-PV and the maroon version as AD12YXL-17-AB-PV. Both match the corresponding options in this listing. The original Frontier XL shape combines a full-height backrest with a wide seat, giving you specific model and size references when comparing the chair with another gaming-seat family.

4D Armrest Adjustment

The armrests provide four-direction adjustment so their position can be configured around a keyboard, mouse or controller. Adjust the seat height first, then work through the available armrest positions with the desk and the device you use most. Consider the clearance beneath the work surface as well as the positions you prefer for different activities at the same setup.

Separate Head and Lumbar Pillows

The Frontier family includes an external head pillow and a larger lumbar pillow, with strap-based pillow attachment identified in the manufacturer’s overview. Their separate construction lets you arrange the contact points after choosing the backrest angle. Position them around your usual seated arrangement, then review the seat and support settings together before returning to your regular desk activities.

Recline and Height Controls

The Japanese manufacturer page lists backrest adjustment from 90° to 160° and a 7 cm height-adjustment reference. Tilt locking provides another seating control, with a Class 4 gas lift supporting height changes. Leave enough room behind the chair for the recline movement, and choose a position that works with the screen, desk and surrounding furniture.

Frame, Foam and Covering

A steel frame and high-density molded foam form the main seat construction. The black and maroon configurations shown by the manufacturer use PVC covering; the selected product option identifies the finish at AX Store. PU-coated casters and the reinforced base complement the chair’s supporting components, providing a construction reference alongside the adjustment and fit features.
