Sorry, no. We carefully test our products to ensure that they are both safe and functional. If it includes casters or feet, we test with them and if it does not, we test without them. We can’t actually verify the structural integrity of a unit if changes are made and therefore, we do not recommend doing so. Additionally, any changes made to the item would void the warranty.
The only exception are adjustable shelves. These do not impact the structure and can be added or omitted.
