Powerbasic Beja Grey Ergonomic Office Chair

An intelligent lumbar support with pressure adjustment, 4D armrests and a continuous 90-145° recline form the ergonomic core of this chair. The system is completed by an SGS-certified class IV gas cylinder and a polished steel base that allows you to work or study for hours without discomfort.

Adaptable lumbar support

The inflatable lumbar cushion adjusts in seconds and follows every micro-movement of the trunk, maintaining the natural curve of the spine and reducing fatigue at the end of the day.

4D armrests and 3D headrest

The armrests adjust 7 cm in height, 6 cm in depth and ±10° in rotation, aligning shoulders and wrists with keyboard or mouse. The 3D headrest rises 10 cm and tilts 70°, relieving the cervical area during reading or video calls.

Dynamic recline

A synchronous mechanism allows lateral rocking of 10° and adjustable recline; just pull the lever to go from a focus posture (90°) to a relaxation angle (145°) without losing stability.

Materials and ventilation

The backrest combines polypropylene reinforced with high resilience grey elastic fabric, resistant to deformation and wear. The seat, made of high-density foam, maintains its firmness over time, while the steel base and the silent PU wheels support up to 120 kg.
