A device (10) which can be transformed between creeper and chair configurations includes a support frame (15) which pivotally carries a first pivotal frame (16) and a second pivotal frame (17). The support frame (15) carries caster assemblies (21, 22, 23) which are positioned to render the device safely mobile in either configuration. A pad (12) is carried by the first pivotal frame (16) and serves as a headrest when the device is in the creeper configuration and a backrest when the device is in the chair configuration. A second pad (13) is hinge connected to the first and second pivotal frames (16, 17) and is maintained horizontal as it translates from the mid-body support of the creeper to a seat for the chair. A third pad (14) is carried by the support frame (15) and serves as a shelf under the second pad (13) when in the chair configuration. A latch assembly (44) automatically maintains the device (10) in the creeper configuration, and a locking assembly (51) automatically maintains the device (10) in the chair configuration. In an alternative embodiment, a device (100) includes a position control assembly (170) is operated by a handle (179) to lock the device (100) in any position from the full creeper configuration to the full chair configuration.
