Optimum Z Office Chair

Optimum Z ergonomic task chair for demanding workstations

Optimum Z is made for workdays where the chair is not an afterthought. It gives the user a high backrest, a double-jointed adjustable headrest, adjustable armrests, seat depth adjustment and separate angle adjustments for the seat and backrest. The main advantage is not one single feature, but the way the adjustments work together. A taller user, a shorter user, a long-legged user and a user with a shorter back should not be forced into the same sitting position. Optimum Z is a heavy-duty task chair with a wide adjustment range, so it can be set up for many body types and many workstations.

High backrest and double-jointed adjustable headrest

The high backrest gives support over a larger area than a low operator chair. It helps the user keep the upper body steady during screen work, documentation, monitoring tasks and detailed bench work. The backrest measures 450 x 610 mm, which gives clear support from the lower back towards the shoulders. The double-jointed adjustable headrest supports the neck and shoulder area without locking the user into one rigid position. Its height and depth can be adjusted, and the two-joint construction makes it easier to find the right angle for the head. The adjustment range of the headrest is 170–270 mm.

Seat depth, backrest height and angle adjustments

Good seating starts with the seat base. Optimum Z has a seat width of 490 mm and an adjustable seat depth of 450–490 mm. Seat depth adjustment helps the user position the seat so that the thighs are supported while the front edge does not press uncomfortably behind the knees.

The seat height can be adjusted from 460 to 590 mm. This range suits many standard desks and technical workstations. The seat angle and backrest angle can also be adjusted, allowing the user to choose a more upright or more relaxed working posture depending on the task. The LiftUp backrest height adjustment locks the back support into the correct position for the lower back. Together, these settings make the Optimum Z ergonomic task chair suitable for people with different leg length, back length and preferred sitting style.

Adjustable armrests included as standard

The Optimum Z chair includes adjustable armrests as standard equipment. The armrests have four height levels selected with a push button, and the width can be adjusted with a strong quick-release fastening. This makes the chair easier to adapt when the task changes.

Durable fabric upholstery for professional daily use

The Optimum Z task chair is available with grey, black or blue fabric upholstery. The fabric has a dirt-repellent treatment, which helps the chair stay cleaner in everyday use. This is valuable in workplaces where chairs are used with work clothes, moved between workstations or placed near production and logistics areas. The upholstery is designed for durability, with an abrasion resistance of 50,000 Martindale. The Dove fabric has a Teflon-treated surface that repels dirt and light splashes. The chair also meets the EN 1021-1 fire safety classification for seating in public areas.

Metal base and quiet PU castors for hard floors

A stable base is important in a heavy-duty ergonomic chair. Optimum Z has a metal five-star base with a 660 mm diameter. The base gives the chair a firm feel when the user turns, reaches or changes position. The gas lift provides the 460–590 mm height adjustment and keeps the seat easy to set for different users. The chair is fitted with soft and quiet PU castors. PU castors roll well on hard floors such as concrete, epoxy and other smooth industrial or office floor surfaces. They are a good choice when the chair needs to move easily without creating unnecessary noise or scratching the floor.
