TECHNICAL DESCRIPTION 1. Description: The standard model (TAB22) is a stackable chair on a cantilever frame, produced by BULO according to a design by Alain Berteau.The chair has a seat shell of shaped multiplex, consisting of 12 layers of beech wood veneer (FSC) with a total thickness of 8mm. The base is a cantilever frame of chromium-plated steel 12mm in diameter. The base is screwed to the seating shell and is fitted with distance holders for stacking. The chair is supported underneath by 4 polypropylene glides. The chair is covered with fabrics or leather on the front side of the seat. The base is asymmetrical so that the chairs can be joined to each other at the sides to make rows. The design of the TAB chair encourages dynamic seating positions due to the extra tablet behind the seat shell, on armrest height. Variants TAB 03 : - seat shell on a height adjustable five star base, lacquered on wheels (hard/soft/with built in brake) - also available on a height adjustable base lacquered, on glides TAB 32 : bar stool on cantilever frame (chromium plated) Also available with felt glides for wooden floors (TAB22/TAB32

5. Links The base is asymmetrical so that the chairs can be joined together at the sides to make rows. And so, the distance between the chairs varies!!! Two plastic clips are fitted under the tub as standard: this clip fixes a set distance between 2 chairs and ensures that the chairs are arranged neatly in a straight line. The clip has the facility to fix two intermediate intervals (an intermediate interval measured between the tubs of either 75mm or 145mm). The choice of intermediate intervals results in one chair’s difference every 12 chairs: 75mm = 12 chairs, 145mm = 11 chairs). This...

8. Norms The chair has been tested positively against the European norm in matters of durability and stability and against the American Bifma standard. • NF EN 13761 European norm which tests general safety norms when the chair is in use (sharp edges, jamming points, etc.) and also states the following normative references: • NF EN 1022(97) = norm stipulation of stability in all directions • NF EN 1728(01) = norm stipulation of strength and durability “Norm 13761 is comparable to the European ISO norm 7173 which tests the same static strains. The ISO norm refers to level 4 = heavy...

The bar at the back is an ideal support for the arms. The height of this ‘armrest’ (32cm higher than the seat) is relatively high, but this is very ergonomic because it takes the strain off several back and shoulder muscles. The backrest is quite low partly because of this, but it does free the shoulder blade area completely and this in itself promotes free movement. The low back support also prevents the lumbar vertebrae in the lower back from sagging. On the other hand, the bar is also a clear handle to move the chair. The bulging in the backrest supports the underside of the backbone...
