Chair frame

The chair frame is crafted from 2 mm thick steel tubing with a diameter of 20 mm in black powder-coated finish (other colours available on request). All chair frames are fitted with protective bars to enable secure stacking and floor-friendly black plastic feet.

Seat shapes

1. Standard shape "F" with rounded front edge
2. Curved shape "S" with rounded front edge and spinal support
The rounded front edge forestalls leg fatigue and circulatory problems. The back support forestalls damage caused by poor sitting positions.
Seating surface: width x depth = 44 x 42 cm.

Seat design

The seat, mounted on elastic rubber elements, is crafted from robust multi-ply beech wood and features ventilation perforation holes. The "F" (flat profile) and "S" (S-shaped profile) seats have a 4 cm thickness of high-quality breathable foam rubber cushioning, a foam rubber thickness of 2.5 cm being optionally available.

Backrest

The backrest pan is made from multi-ply beech wood and covered with a synthetic material covering. The backrest cushioning is a 3 cm thick layer of high-quality breathable furniture-grade foam rubber. Its moveable mounting on back upright allows it to adapt perfectly to the user's posture

Fabric cover

The chair has a high-quality, flame-retardant upholstery fabric made of Trevira® CS fibers (meets fire protection form B1) with a rub resistance of 100,000 Martindale (maximum durability). The standard colour is noble anthracite.

Fabric colours
2 or 3 tone mixtures: red, wine-red, blue, anthracite (standard)
solid colour: black

We strongly recommend 2 or 3 tone soil-resistant fabrics. However, custom upholstery is available on demand.

Stackability

All Kolberg orchestra chairs can be stacked, free-standing. Sturdy plastic covers protect the chair frames. Stacking bars ensure balance and prevent contact between frame and upholstery.
