This JEGS Rolling Seat with Tool Tray is a very functional mobile workstation. The molded seat is designed for function and comfort when sitting over long periods of time. Carrying this unit around would be awkward if it were not for the cut-outs built right into the seat bottom for easy lifting. The large plastic tool tray holds several tools and the seat swivel makes it easy to locate your tools or parts no matter where you left them. This model features 4" casters that are the key to its mobility. These premium casters are constructed pliable rubber which allows the technician to roll right over rough terrain. The adjustable seat height can get down to a low level where a number of jobs take place (most notable - brakes). Grab one today and give it a spin.
