|Mechanism function||The swivel and tilt mechanism operates on a coiled spring which is adjustable by means of a tension knob, catering for various body weights.
When the gas height adjustment is used, the movement has a duel lever which locks the movement in a forward position as well as operating the gas height mechanism.
|Body weight tension control||The body weight tension control is variable, range from 40 to 120kg with a static load of 130kg in accordance to BIFMA standard.|
|Seat||Injection moulded plastic honeycomb structure seat, ergonomically designed to distribute pressure loads across the entire seat surface. The seat design has been engineered to carry a maximum static load of up to 120 kg. The seat is made of 50% virgin plastic and 50% recycled plastic.
The seat height can be adjusted (135mm range) by means of a class 4 type gas cylinder. The cylinder is housed in a 50,8mm diameter by 2mm wall thickness steel tube, designed with a shock absorbing effect to enhance comfort and minimize spinal injury when sitting down.
|Backrest||Injection moulded honeycomb structure backrest. The backrest is made up of 50% virgin plastic and 50% recycled plastic.
|Armrest||Injection moulded armrest with reinforcing “rib” construction.|
|Base and castor||The 5 star base is a reinforced injection moulded talc free nylon / glass fibre filled base with lattice construction. The base has an inner steel cone ring moulded into the hub section for additional strength. The base can carry a static load of 150 kg.
The castor is an open dual (twin wheel design), 50mm diameter castor. Each castor carries a minimum load of 250 kg. The pin insert is an off-set load bearing type to ensure quick alignment in any direction, giving total manoeuvrability.
|Upholstery options||Fabric on the seat and back.|
