A lift system has a back panel and a seat panel to provide a seat. The back panel is slidably mounted on a support column via slider so that the back panel can be moved up and down to adjust the seat height. The seat panel can be flipped back when the back panel is in an upright position. The back panel, together with the support column, can be oriented in a horizontal position and the seat panel can be adjusted similarly. With the support column, the lift system can be attached to a wheeled frame for mobility, but it can also be attached to a pole, a rotatable arm, a wall or a ceiling.
