The difference between standard workbenches and modular workbenches is that modular workbenches allow for customization. They can be assembled or reassembled for dedicated or changing uses. A combination of drawers and cabinets can form the support pedestals, or select simple panel legs. Also select from different types of risers, stackable drawers, shelves, rail kits and more for further customization. The more workbench components you add, the more you can tailor it to your needs. Options vary by dimension, load capacity, and work surface material among others.
