Werksitz ESD Safe series chair, load capacity 175 kg

The WS 1689.10 KL ESD model is an industrial work chair designed for EPA zones where electrostatic discharge control and structural stability are essential. Although it offers the same 175 kg load capacity, this version differs from the castor-based variant in its base design and adjustment range.

The seat and backrest are made of antistatic synthetic leather, ensuring easy cleaning and durability in production environments. The chair is built on a five-star cast aluminium base with a 713 mm diameter, equipped with glides instead of castors. This configuration increases stability in workstations where mobility is not required and a fixed, secure working position is preferred.

The chrome gas spring allows seat height adjustment from 445 to 535 mm in accordance with DIN 68877. The seat tilt can be adjusted from +1° to +8°, while the backrest tilt ranges from -10° to +8°. The seat locking mechanism operates continuously, enabling precise adjustment of the working position.

Structural and ESD parameters

The total chair height ranges from 740 to 920 mm. Seat thickness is 60 mm, and backrest thickness is 50 mm. The seat dimensions are 540 × 470 mm, and the backrest measures 510 × 420 mm. The total weight of the chair is 17.35 kg. The chair complies with EN 61340-5-1-1 in terms of electrical conductivity within the range of 10⁴–10⁶ Ω, confirming its suitability for ESD-controlled environments.
