Office chair CALMA (#3715)

This office chair is designed to provide a wide variety of ergonomic support and practical adjustability for modern work environments. The chair integrates a breathable mesh backrest with a fabric-upholstered seat, combining airflow with cushioned seating comfort. 

This material configuration helps maintain ventilation around the back while providing a supportive seating surface suitable for extended working periods. 

The upper section incorporates a 3D adjustable headrest, allowing users to modify its height, depth, and angle to better support the head and neck. This adjustability helps reduce strain in the cervical area during prolonged desk work. 

Integrated into the backrest is a 2D adjustable lumbar support element with foam padding. The lumbar component can be repositioned to match the natural curvature of the lower spine, helping to promote proper posture and provide additional lower back support.

User comfort and adjustability are further supported through the inclusion of 3D adjustable PU armrests. These armrests allow adjustments in multiple directions, enabling users to position arm support according to desk height, typing position, or individual ergonomic preference. The armrest surfaces are finished with PU padding to provide a stable and comfortable contact surface during daily use.

The seat is constructed with moulded foam to ensure consistent density and long-term shape retention. Moulded foam technology distributes pressure evenly across the seating surface and reduces compression over time compared with traditional foam padding. 

The chair is equipped with a four-position adjustment mechanism. This mechanism allows the tilt resistance of the chair to automatically adapt to the user’s body weight, while also offering multiple lockable recline positions for different working postures. 

The structural base consists of a reinforced R340 nylon base designed to provide stable weight distribution and long-term durability. The base is fitted with 60 mm nylon castors that allow smooth movement across a variety of office floor surfaces while maintaining low rolling resistance.

Overall, this office chair combines breathable materials, ergonomic adjustability, and durable structural components. The mesh backrest, adjustable lumbar support, 3D headrest, moulded foam seat, and multi-position tilt mechanism work together to create a seating solution designed for prolonged use in both home and professional office environments.
