The Ultra-Lightweight Aluminium Wheelchair
Meet the RGK Tiga Sub4, a wheelchair so light it tips the scales at under 4kg*. By making 72 subtle but critical design improvements to the original Tiga, RGK has created a groundbreaking lightweight chair that maintains the rigidity, stability, and durability you need for everyday life.
Transferring, lifting, propelling, and turning are effortless, thanks to its aerospace-grade aluminium frame and thoughtfully engineered weight-saving components. Super-lightweight Froglegs castors with aluminium centres, carbon fibre sideguards and footplate, titanium fasteners, and a nylon footrest mount with Easy Adjustment System all combine to minimise weight without compromising strength or performance.
Like all RGK chairs, the Tiga Sub4 is made to measure, with over 30 individual measurements ensuring the most comfortable and efficient fit possible. Airtech Technology provides breathable, tension-adjustable seat and back upholstery for all-day comfort. Personalisation options, including polished, brushed, or powder-coated finishes, accent colours, and embroidery, let you make your Sub4 uniquely yours.
*Guaranteed less than 4kg (excluding wheels and cushion), the Tiga Sub4 redefines what an ultra-lightweight wheelchair can achieve, without ever compromising strength, stability, or style.
