Invacare
A centre-wheel drive powerchair range built around SureStep suspension and Stability Lock technology, keeping all six wheels on the ground over kerbs and uneven surfaces. From the everyday SP2 through to the narrow-base, low-seat and teen variants.
Overview
The TDX range is built around Invacare's SureStep suspension and Stability Lock technology, keeping all six wheels on the ground over kerbs and uneven surfaces so the chair doesn't lurch or jolt as it climbs obstacles. True centre-wheel drive gives a tight turning radius for confident indoor and outdoor use, and every model shares the LiNX Smart Technology control system and Modulite seating platform.
TDX SP2: the standard adult base – higher weight capacity and larger batteries for longer range.
TDX SP2 NB: a narrower base for tight doorways, compact homes and classrooms, with the same seating and technology.
Low Rider, NB Ultra Low Maxx and Teen variants cover WAV transfers, complex postural needs and smaller frames – see the full range below.
Users who need full functionality without compromising on style, from everyday indoor and outdoor use through to more complex postural support with powered tilt, recline and elevating leg rests.
We'll help you find the right base and seating combination for your budget and needs during assessment.

They share the same seating and LiNX technology. The SP2 has a wider base, higher weight capacity and larger batteries for more range, while the NB has a narrower base for tight indoor spaces. We'll help you choose during assessment.
It keeps all six wheels firmly on the ground on uneven terrain, so the chair stays steady rather than rocking or tipping as it crosses kerbs and obstacles.
Selected models are crash tested, so the powerchair can be used as a seat while travelling in an adapted vehicle. We'll confirm which configuration applies during assessment.
We're an approved supplier for Access to Work, NHS, local authorities and insurance companies. We can talk through funding routes during your assessment.
