Technical Specification

Foam:

The Seat is made in Moulded foam of 55 density in all models. The Back made of Moulded foam of 55 density is used in models wherever available. Polyurethane foam of 32 or 40 density & 2" thickness is used in models where moulded foam of 55 density is not available.

Base:

Five prong fibre base (70% Virgin Nylon & 30% Glass Fibre) OR Five prong m.s. base of 14 gauge and powder coating upto 40 microns OR Five prong metal base with wooden cover OR Five prong base of stainless steel

Fabric:

Normal Fabric @ Rs.120/- per metre is used for all models.

Gas Lift:

Suspa of West Germany OR Ivars of Italy OR MDI of Malaysia.

Armrest:

Adjustable height arms are used in certain models Soft Polyurethane (P.U) Armrests are used in select models. Metal arms are used in a few models. Hard plastic (PP) arms are used in certain models. Wooden armrests are available in select models.

Plywood:

Hot – pressed termite & borer proof plywood of 12 mm thickness is used for the seat and back 'T' – nut technology is used to ensure a longer life of the plywood.

Castors:

Regular Twin wheeled castors (70% Virgin Nylon & 30%Glass Fibre) for carpet surface OR Special Twin wheeled castors (70% Virgin Nylon & 30%Glass Fibre) with polyurethane tread for hard flooring.

Seat and Back Covers:

Polypropylene seat & back covers are used in select models. Made by injection moulding. ABS seat & back covers are used in select models. They are made of ABS plastic by injection moulding.

Rubber Binding Solution:

It is manufactured by 'Pidilite' or 'Speb 7'. The solution is chloroform/benzene free.

Bolts:

Bolts are powder coated and are available in various mechanisms.

Column-Tilt Mechanism Bolt (CTMB):

In a CTMB, the seat, and the back tilt on the outer side with the same degree and changes the angle of the seat and the back relative to the floor. The chair pivots at the top of the base post and lifts the knees slightly while the back descends. Such a movement can also be locked. The tension of the TMB can be adjusted to make the tilting movement hard or soft depending on the body weight.

Push Back Mechanism Bolt (PBMB):

In a PBMB, the seat remains in the same position(the angle of the seat with relation to the floor does not change) whereas the back reclines on the outer side. Such a movement can also be locked. The tension of the PBMB can be adjusted to make the push back movement hard or soft depending on the body weight.

Syncro-Tilt Mechanism Bolt (STMB):

In a STMB, there is a syncronised movement of the seat and back. i.e. when you lean back, the seat tilts 1 degree for every 2-degree tilt of the back. Such a movement can also be locked. The STMB can be adjusted to make the movement hard or soft depending on the body weight.

Revolving Bolt (RB):

In a RB there is only a rotation of seat & back in 360 degrees.

Knee Tilt Mechanism Bolt (KTMB):

In a KTMB, the mechanism allows you to keep the feet flat on the floor while reclining. This is made possible by having the pivotal point for the knee tilt close to the front of the seat, thus preventing the front of the seat from rising while tilting backwards. The knee lift is negligible, but the back and head descend more than in a regular tilt chair. The tilt tension knob allows for control of the tilting effort according to the body weight to adjust the tilt tensioning.
