Sold as a pack of 4, these Elephant Feet raisers provide a lift of 140mm (5.5\") for various items of large furniture such as chairs, sofas, beds and tables.They are very strong and robust, with a deep, non-slip recess at the top, and they are made of a single piece of tough plastic so there are no seams or joints that could come apart under stress. The recess is deep enough to hold a castor - and most other types of leg - very securely and the broad base makes it extremely stable. The neutral light grey colour makes it unobtrusive in most environments.
