Drawers open on 2 different sides of this creeper seat, each with an inner space of 9 by 5.5 by 1.5 inches for wrenches, sockets and shop rags, and a round tray plus twin can holders sit on top for the tools in constant use. The tray alone is rated for 155 lbs. Lift the 12 inch round seat cushion off its base and it becomes a kneeling pad for work down at wheel level; padded with 2 inches of pearl cotton under waterproof faux leather, it wipes clean of oil. Four 2 inch swivel casters run quiet and wear-resistant, taking you from the front of a vehicle to the back. The reinforced metal frame holds 330 lbs at 16 inches wide and 17 inches tall, weighing 13 lbs.
