## Long description

ActiveJet YK848 is a modern ergonomic office chair in black with a mesh backrest and textile-upholstered seat. The chair is designed for everyday use at home or in the office and features a wide seat (48.5 × 52 cm) and a tall mesh backrest (50.5 × 57 cm) that provides full support for the back. Built-in adjustable elements such as a height-adjustable headrest, 6D armrests and a multi-function mechanism allow the chair to be adapted to different body shapes and work positions. The breathable materials and foam-padded seat ensure comfort during prolonged use.
Advantages
The chair combines ergonomic contours with a supportive three-part lumbar section and a full-length adjustable headrest to promote correct posture and reduce strain during long working sessions. 6D armrests offer extensive adjustability (height, depth, rotation and lateral position) to relieve pressure on arms and shoulders. The breathable mesh backrest and textile-covered seat with quality foam improve air circulation and sitting comfort. Additional features include a pull-out padded footrest, recline up to 155°, 360° swivel and a five-star steel base with casters for smooth movement.
Suitable for
Office workers who sit for extended periods
Remote workers and home office setups
Students and people studying for long sessions
Users who need adjustable support for spine, neck and arms

How to use
Adjust the seat height with the pneumatic lift so your feet rest flat on the floor and your thighs are roughly parallel to the ground. Use the multi-function mechanism to set the backrest angle that supports your lumbar curve and recline up to 155° when you need a break. Set the headrest height and rotation to support your neck, and position the 6D armrests to align comfortably with your desk height and typing position. Pull out the padded footrest to relax when required.
Usage recommendations
For ergonomic benefits, regularly change posture during long sessions, ensure the lumbar section contacts the lower back, and set armrests so shoulders remain relaxed. For optimal comfort and longevity, avoid exposing the mesh and upholstery to direct sunlight for extended periods and follow basic cleaning instructions for textile and mesh materials.
