Features: Drive Medical Duet Transport Wheelchair Rollator Walker Combines the features of a rollator and transport chair in one unit. An individual can ambulate independently or be pushed safely by a caregiver. To use as a transport chair, the Duet has locking flip-up armrests and a flip-down footrest to aid the user. A safety lock release is used to store the arms and a strap strap is used to store the footrest while using the Duet for ambulation. The tool-free two position contoured padded backrest is reversible depending on whether you are using the Duet as a rollator or transport chair mode.
