Casters affix to the bottom of furniture, allowing you to move heavy pieces without putting out your back! Practical, but usually not very exciting. We are only interested in the best of the best. Only the most unique and contemporary furniture wheels. Take a look - we think you’ll agree! Note the load bearing properties of static and dynamic weight capacities: static load bearing is the weight applied without any build up of energy, and therefore is to remain motionless. Force, pressure, and gravity remain static or are applied gradually. A dynamic load bearing is measured by the application of rapid force or pressure to an object.
