Abstract A wheeled walker for ambulatory patients and people requiring support while walking includes an adjustable and separable frame and an adjustbable height seat and handlebar. The frame includes a front generally inverted U-shaped section coupled to and supported by fixed front wheels. A height adjustable handlebar is slidably and lockably received in the front frame section. A centrally disposed frame member is curved and directed to the rear. The rear frame section includes a member which adjustably couples to the centrally disposed front frame member and a vertically adjustable seat. The lower portion of the rear frame section is bifurcated and receives a pair of pivotable casters.
