Kolberg Percussion proudly presents the further developed successor of top-of-the-line model 3100H.
Users of our double-bass chairs are already familiar with the possibility, to adjust not only the height and inclination of the backrest and the inclination of the seat but from now on also the height of the seat while sitting. The mechanical height adjustment of our so far most comfortable orchestra chair 3100H with its slightly more awkward handling has been replaced by a more comfortable gas spring with release lever. Despite the technical redesign the chair remains safely stackable.
Seat height: approx. 48 - 54 cm, fluid pneumatic height adjustment with release lever
Seat adjustment: fluid inclination adjustment up to 20° with eccentric quick-release fastener
Seat shape: standard "F" = flat
Backrest inclination: fluid adjustment of height via knurled screw, fluid adjustment of inclination via pneumatic mechanism with release lever
Frame: black powder-coated
Stackability: at least 6 chairs, free standing
Control elements
The user-friendly knurled screws and the pneumatic spring release lever with break-proof bearing enable a comfortable adjustment while seated. The desired position, once set, is firm and steady.
Seat height
All "Comfort line" orchestra chairs feature pneumatic height adjustment.
A safety pneumatic spring mechanism allows fluid, smooth, silent height adjustment by means of a release lever.
Chair frame and seat height
The chair frame is crafted from 2-mm thick steel tubing with a diameter of 20 mm, black powder-coated finish (other colours or high-gloss chrome-plated available on request). All chair frames are fitted with protective bars to enable secure stacking and floor-friendly black plastic feet. If necessary the seat frame height can be increased by 30, 40 mm by simply adding on the appropriate extensions (see accessories).
Seat inclination
The seat inclination can be fluidly adjusted by up to 20° by means of a sturdy, user-friendly eccentric quick-release fastener. Once set, the position is firm and steady.
Seat shapes
Standard shape "F" with rounded front edge
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.
Backrest adjustment
The backrest inclination is adjusted by means of a TÜV-tested (Association for Technical Inspection) safety pneumatic spring with release lever with break-proof bearing. Thanks to extreme lift of the pneumatic spring, the backrest provides support even when seated in the foremost seating position. The removable backrest can be adjusted in height fluidly and silently by means of a knurled screw. The position set is firm and steady.
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
In January 2014 we started to supply our chairs with a new and better fabric of flame-retardant Trevira® CS with abrasion resistance of 100,000 rubs (Martindale).
Standard colour: anthracite (flecked with grey, insensitive to dirt)
From a distance of 2 - 3 m on the difference between old and new fabric cannot be discerned any more.
Fabric colours
2 or 3 coloured melange: red, wine-red, green, blue, anthracite (standard)
solid coloured: black
Other colours and fabrics are available on request. We recommend fabrics that are 2 or 3 coloured, as they are insensitive to dirt.
