At first glance, the Permobil M1 looks like any other Corpus-based wheelchair; however, it's not a Corpus base at all. This new highly-adaptable system accepts most after-market seating components.
Permobil’s most emblematic feature, rightfully, is its Corpus seating system. After all, it remains the original ergonomic power wheelchair seating system, designed by renowned Swedish ergonomist, Bengt Engstrom, over two decades ago.
However, as revered as Corpus seating remains, Permobil knew that it wasn’t an end-all solution. While Corpus seating has some adjustability, it’s an all-encompassing seating system that, by its nature, limits adaptability. Sometimes this prevented power wheelchair users with custom seating needs from using a Permobil.
But now, the newest model in the Permobil lineup, the M1, allows the adaptation of highly-custom seating. Looking at the M1, you might have difficulty telling it apart from the best-selling Permobil M3 (or M300) mid-wheel power wheelchair. And that’s by design. While there are a few differences between the M1 and M3 power bases — 5 mph versus 6 mph, for example — the biggest difference is in the seating. The M1 forgoes Corpus seating for a highly-adaptable system that accepts virtually all aftermarket seating components.
The M1’s seating starts with 1-inch tubular back canes, to which aftermarket backs — from Jay to ROHO to ADI — mount. Additionally, a custom molded back can be fitted. From there, the seat features a universal track system for mounting positioning components, such as thigh guides, knee adductors, positioning belts and so on. Of course, all cushions are compatible, and Permobil has their well-proven flip-back arms. The seating is available in static or tilt-only versions, so multiple power functions, such as lift and recline, are unavailable (although there is a manual recline option).
With seat sizes from 14-by-14 to 22-by-22-inch, the M1’s seating covers a wide range of chair users — especially when its versatile custom seating is figured in.
