Memory-Foam Head and Lumbar Support

The R3 features enlarged head and lumbar supports made with soft, dense memory foam. These cushions provide separate support points around your seated position, complementing the chair’s high backrest. Arrange them to suit your posture when you sit down, whether you are preparing for a match or concentrating on desk work.

A 10.5 cm Seat Base

The seat base uses cold-molded foam and measures 10.5 cm thick, giving the R3 a substantial cushion beneath its perforated PU upholstery. The backrest uses cut foam. This combination provides different internal construction for the two areas while keeping the same coordinated exterior across the chair’s seat and back.

Two-Direction Armrest Adjustment

Adjustable 2D armrests let you position support beside your desk, with an armrest height range of 28.5–36.5 cm. Set them alongside the seat height to suit your keyboard and mouse position. The controls give you room to refine your setup as you switch between desk activities throughout the day.

Recline from Upright to Relaxed

The backrest reclines through 90–180 degrees, allowing a wide range of seated positions. A Class 4 gas lift adds 8 cm of height adjustment, placing the seat top 48–56 cm above the floor. Use the height and recline settings together when fitting the chair around your desk and preferred sitting position.

Steel Frame and Base

A steel frame and steel base support the R3, while 60 mm casters allow it to move around your workspace. The maximum supported load is 150 kg, and the base diameter is 70 cm. These specifications give you a clear starting point for checking the chair’s capacity and available floor-space requirements.
