Abstract
A mobile storage unit comprises a rigid frame coupled with a top seat portion, a pair of wheels and a number of supports. The wheels are coupled to a wheel mechanism that retracts the wheels into a retracted position when a downward force is applied to the rigid frame in an upright position. As a result, at least one supplemental support that is positioned above the ground when the pair of wheels are in the extended position, touches the ground when the pair of wheels is in the retracted position thereby adding support and stability to the mobile storage unit when in the upright position.
