Ergonomic Office Chair Expert 5.3 Grey Mesh

Designed for Comfort and Health

Mark Adler Expert 5.3 Grey Mesh ergonomic chair

Modern office chair combining solid workmanship with extensive adjustment, so you can fit it to your individual figure and work mode. Features include slide technology for seat adjustment, durable ventilated Mesh HD fabric, and a SeatRest backrest that tilts up to 135°.

Achieve Perfect Seat Depth

Adjustable seat depth detail

The innovative slide function allows you to move the seat precisely front to back. This makes it easier to adjust the position to the length of your thighs, improving circulation and reducing the feeling of numbness in the legs during long hours of work.

Breathable Mesh HD Fabric

Ventilated Mesh HD fabric detail

Body contact points are upholstered with abrasion-resistant Mesh HD fabric. This ensures optimal air circulation and long-lasting comfort, keeping you cool and focused throughout the day.

SeatRest Reclining Backrest

Reclining backrest up to 135 degrees

Relax your back with the SeatRest function, which allows the backrest to tilt up to 135°. With the ability to lock in your preferred positions, this feature significantly increases the versatility and comfort of your chair.

Customized 2D Lumbar Support

2D adjustable lumbar support

Two-way adjustment allows the lumbar support point to be set both vertically and horizontally. This helps maintain the correct curvature of your spine and effectively reduces tension in the lower back region.

Dynamic 3D Armrests

3D adjustable armrests detail

Enjoy precise positioning with 3D adjustable armrests. You can easily adjust their height, depth, and angle to perfectly align with your desk and individual ergonomic preferences.

Supportive Adjustable Headrest

Adjustable headrest detail

The adjustable headrest provides essential additional support for your neck and head. It is perfectly designed to enhance comfort during focused work as well as short moments of rest.

Floor-Friendly Casters

Polyurethane-rubber casters detail

Equipped with 6 cm polyurethane-rubber casters, this chair minimizes the risk of floor scratches. They withstand abrasion better than standard plastic casters while providing smooth and stable movement on a variety of surfaces.
