Rousseau’s drawers in shelving enable storage of large, bulky items as well as smaller items in the same space. In addition to maximizing available space, a hybrid storage system with shelving and drawers allows users to easily find stored items. Drawers are equipped with 100% extension. Users can save the space equivalent of six traditional shelving units using one high density storage unit, thereby increasing space without increasing square footage. Drawers can also be installed in more than 35 different brands of shelving the user might already have.
