Optimum N Work Chair

Optimum N ergonomic work chair for adjustable daily seating

The Optimum N ergonomic work chair is a solid choice for workplaces where a chair is used often, adjusted often and expected to feel steady throughout the day. Optimum N gives the user practical control over the seat, backrest and armrests without making the chair complicated to operate. The low backrest gives support where it is needed, while still keeping the upper body free for reaching, turning and working close to the desk or bench. It is a good option when the user needs support but does not want a large, high-back office chair that feels bulky in a tighter workspace.

Low backrest with integrated lumbar support

A good work chair should support the back without forcing every user into the same sitting position. The Optimum N office chair has a low backrest with a width of 440 mm and a height of 590 mm. The backrest can be raised and lowered with the LiftUp mechanism, making the adjustment quick when users change or when the task requires a different position.

The integrated lumbar support follows the backrest height adjustment. This is useful in shared workstations because the lower back support can be positioned to suit the user instead of staying fixed in one place. The result is a more natural sitting position and better support during long periods of seated work.

Seat and backrest angle adjustment for different tasks

The Optimum N ergonomic work chair includes separate angle adjustment for the seat and backrest. This makes it easier to adapt the chair to the work being done. When a user is working close to a bench, checking parts, using a computer or handling documents, the preferred sitting angle may change. Independent adjustment gives more freedom than a fixed chair or a basic swivel chair.

The seat is 490 mm wide, with seat depth adjustment from 450 to 490 mm. This helps the chair fit users of different heights. A seat that is too deep can press behind the knees, while a seat that is too shallow may not support the thighs properly. With seat depth adjustment, the user can set the chair closer to their own body size and working position.

Adjustable armrests for better upper body support

Arm support is especially important when the hands are used for keyboard work, inspection, small parts handling or other repetitive tasks. The Optimum N adjustable work chair has armrests that can be set to four different heights with a simple push-button mechanism. The width of the adjustable armrests is set with a hand-tightened mechanism, so the chair can be adapted to the user and the desk width.

Stable metal base with PU castors

The Optimum N industrial chair is built with a metal star base on castors. The base gives the chair a stable feel in daily use, and the PU castors make it easier to move at the workstation when the user needs to reach nearby shelves, drawers or work surfaces. The seat height range is 460–590 mm. This makes the chair suitable for standard desk and workstation heights where a seated working position is needed. The height adjustment helps the user bring the chair to the right level for the table, tools or screen, which is one of the basic requirements for an ergonomic work chair.

Dove fabric upholstery for a professional look

The chair is upholstered in Teflon-treated Dove fabric. The fabric has an abrasion resistance of 50,000 Martindale, which is a practical figure for a chair intended for repeated use in a professional environment. The fire classification is EN 1021-1. The Optimum N office chair is available with grey, black or blue fabric upholstery.
