Sunrise Medical (US) LLC
An ATP & Clinician Best Pick of 2015:
The QM-710 is made by Sunrise Medical and up until its introduction, patients did not have a good center-wheel-drive option, one that would handle well outdoors and still climb their ramps and lifts without needing to have some momentum behind it. That is because of the SpiderTrac suspension that it has — as the front wheels raise up to meet the new terrain, the drive wheels are forced down to keep good traction. The chair has a great turning radius for indoor mobility and great outdoor capability.
