Another popular acronym in the interior design world, and particularly around hotels is OS&E, which stands for Operating Supplies and Equipment. What is the difference between OS&E and FF&E? Think of it this way, if FF&E includes the loose products that a guest or member of staff interacts with, then OS&E are the pieces that they need to operate within the space. Typically OS&E are products that do not need to be installed. So, for a hotel project, OS&E includes items such as towels, bed linen, crockery and glassware, irons and hairdryers etc. it also includes products and items that staff uses, such as uniforms, office equipment and cleaning equipment.
