PRO-TECH — adjustable support for practical workspaces

Stema PRO-TECH — front three-quarter view

The STEMA PRO-TECH is a work chair for workshops, laboratories and production spaces. A 38–50 cm seat-height range and adjustable backrest help you fit the chair to your workstation, while soft castors allow movement across hard floors.

Soft TPU foam seat and backrest

Stema PRO-TECH — textured moulded TPU seat and height-control leverStema PRO-TECH — shaped TPU backrest with integrated handhold

The shaped seat and backrest are made from soft moulded TPU foam. The armless design leaves the working area accessible, and the black seat, backrest and base give the chair a consistent finish. No headrest is fitted.

Adjustable backrest height

Stema PRO-TECH — backrest height adjustment shown by the red position overlay

Adjust the backrest height through 4 cm of travel. Loosen the corresponding screw, set the backrest position and secure it again.

Backrest angle adjustment

Stema PRO-TECH — manual backrest-angle adjustment shown in two positions

Set the backrest tilt angle with the manual control and secure the corresponding screw after adjustment. The supplier does not specify a numeric angle range.

Backrest depth adjustment

Stema PRO-TECH — backrest depth adjustment at the seat attachment

Adjust the backrest depth through 2.5 cm of travel to position it relative to the seat. This is a backrest-depth adjustment rather than a sliding-seat mechanism.

Class 4 gas lift and adjustable seat height

Stema PRO-TECH — seat height adjustment shown by the red position overlay

The class 4 gas lift adjusts the seat height from 38–50 cm using the lever beneath the seat.

Soft castors for hard floors

Stema PRO-TECH — five-star nylon base and soft castors

The 70 cm nylon five-star base is fitted with 50 mm soft castors suitable for hard floors. Use an appropriate protective mat where additional floor protection is needed.
