STEMA PRO-TECH Workshop Chair with Castors
STEMA PRO-TECH Workshop Chair with Castors is backordered and will ship as soon as it is back in stock.
PRO-TECH — adjustable support for practical workspaces
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
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
Adjust the backrest height through 4 cm of travel. Loosen the corresponding screw, set the backrest position and secure it again.
Backrest angle adjustment
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
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
The class 4 gas lift adjusts the seat height from 38–50 cm using the lever beneath the seat.
Soft castors for hard floors
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.
Dimensions
Overall height: 86.5–98.5 cm; seat height: 38–50 cm; seat width × depth: 47 × 44 cm; base diameter: 70 cm. The supplier states a dimensional accuracy of 1 cm.
Documented testing and care
A positive model-specific safety, strength and durability report is available. The foam arrangement also has positive cigarette and match-flame-equivalent ignitability test results; these results apply to the tested material and conditions. The operating instructions specify a maximum user weight of 130 kg and use for up to 8 hours per day. Clean with mild products and protect the chair from rain, moisture and direct sunlight.
