Quantum Rehab's Stretto: Slender Profile, No Compromise

For every 36"-wide hallway encountered by ATPs
and clinicians during home assessments, there is a
much narrower hallway in a smaller, older house,
apartment, or mobile home. While it would be optimal for
power wheelchair users to live in wide-open spaces, the
reality is that wheelchair professionals need to meet their
clients where they are…
and where they live.
It’s a challenge familiar
to the clinical and
engineering teams at
Quantum Rehab, and
one they answered with
a new power wheelchair
called the Edge 3 Stretto.
Customizability in a
Stretto is Italian and translates
as narrow, close, or
tight. The Stretto’s width is
the first thing you’ll notice:
It’s 21" wide using 14" drive wheels, or 20.5" wide
with 12.5" drive wheels. That’s thanks to two NF22
batteries sitting inline, rather than side by side — and all
the better to maneuver well in tight spaces.
But a svelte figure is just the start of what the Stretto
offers, said Jay Brislin, VP of Quantum Rehab.
Quantum Rehab’s international R&D team floated the
idea of a power base with a narrow width that could
also traverse terrain and provide a high-quality ride. Did
Quantum’s North American team want to be involved?
“We said absolutely,” Brislin recalled. “Obviously, the
footprint intrigued us immediately. We felt the industry
really needed that kind of footprint. There are chairs that
have that footprint, but there aren’t chairs that have that
footprint and are in the Group 3 category. That makes
[the Stretto] a unique product. Now you’re looking at a
chair that can do two different drive wheel types, either
a 12.5" drive wheel or a 14" drive wheel.”
From the beginning, Brislin said, the Stretto’s calling
was also to have full-fledged Group 3 capabilities.
“We couldn’t put U1 batteries in it, because it wouldn’t
pass Group 3 criteria,” he explained. “So we used NF22
batteries, and we ran them in parallel so you were able
to get that narrow width at the base.”
The Stretto accepts full powered seating, from tilt and
recline to elevating legrests and iLevel, Quantum’s power
adjustable seat height. The Stretto can be driven at up to
3.5 mph while elevated 12".
“Anywhere from static seating all the way up to
multiple power,” Brislin said of the Stretto’s seating
