A rotatable stand-up wheelchair or invalid mobility device which includes a main drive chassis having front and rear wheels. A means for raising and lowering the seat and back portion of the wheelchair raises and lowers the invalid from a substantially seated position on the seat to a substantially standing position supported by a foot plate attached to the base of the wheelchair. Stability of the wheelchair device is maintained by two triangular wheel configurations intercepting at their apex. In operation, the invalid can move while standing in such a fashion as the foot plate may be lowered to a close proximity to the ground so that the invalids hand approximates the level of a hand height of a non-handicapped person. This simulated normal motion and enables direct contact with countertops and other work surfaces.
