Abstract: A storage assembly includes a storage cabinet removably mounted to a wheeled base which is supported by a supporting surface such as a floor. A guide assembly is interconnected with the floor and the base for guiding movement of the base in a longitudinal direction, so as to provide movement of the storage cabinet between an extended position and a retracted position in response to application of an axial pull-out or push-in force to the cabinet. The guide assembly includes an inner mounting member secured to the floor, and an extendible and retractable guide mechanism extends from the inner mounting member. The guide mechanism may be in the form of a telescoping drawer slide assembly including a fixed-position member secured to the inner mounting member and an extension member secured to and interconnected with the base and slidably mounted to the fixed-position guide member.
