Provided are mechanisms and processes for an adjustable mobility assistive device. In various examples, the adjustable mobility assistive device includes a first frame including a slotted rail S1 and a slotted rail S3 coupled by post P1 and post P3. Both slotted rail S1 and slotted rail S3 may be quarter circular in shape. The adjustable mobility assistive device also includes a second frame including a slotted rail S2 and a slotted rail S4 coupled by post P2 and post P4. Both slotted rail S2 and slotted rail S4 may be quarter circular in shape. Post P2 is slidably connected to slotted rail S1 and slotted rail S3, and post P3 is slidably connected to slotted rail S2 and slotted rail S4. Post P2 is adjacent to post P3 when in a fully extended position and post P1 is adjacent to post P2 and post P3 is adjacent to post P4 in a retracted position.
