The 2-in-1 40" Z-Frame Folding Creeper, No. W85018, from Performance Tool, converts from a creeper to a rolling seat for automotive and shop needs. Fully padded cushions create a comfortable surface for laying flat or sitting upright, and six shielded 2" swivel casters allow for easy 360-degree movement and added stability. The creeper mode offers a low profile design that provides improved clearance, with dimensions at 40" by 16-7/8" by 5-1/8", and a 300-lb capacity. The rolling seat size is 20-1/2" by 16-3/4" by 16-7/8" and has a 286-lb capacity. The locking pin in the seat configuration prevents unwanted movement and retracts easily for quick conversion.
