The present invention provides a wheelchair device configured to reduce the likelihood that a user might fall out of a wheelchair. The device includes a wheelchair frame, a lever, and a seat cushion, whereby the seat cushion is flexible and configured to sink into a recessed and angled orientation when occupied by a user. The sunken seat cushion serves to encourage a user to attain proper posture and further serves to reduce the chances that a user might fall forward out of the seat. The lever of the present invention is attached to the underside of the wheelchair device and comprises a handle portion and a flat base portion with a curved upper surface. A forward actuation of the handle results in the lever rotating about the wheelchair, causing the base to contact and lift the seat cushion to a level that facilitates the exiting of the wheelchair device.
