Every two parts of this cart swap positions during assembly, so the tier spacing follows what is being stored rather than a fixed factory layout. Trays lift out to be carried to wherever the work is happening and slot back afterwards. Each tier stands 3 in deep. All-PP construction weighs 4 lbs and carries 80 lbs. It measures 15.5 x 14.5 x 30 in. White throughout, and the plastic wipes clean rather than staining. The same design is offered in a 3-tier configuration.
