Removable liners are a bean chair lining within a bean chair . They are made of a durable, water resistant polyester fabric. They are easy to remove for when you want to wash the outer bag as they prevent spillage of the beans, we highly recommend this option. It also provides added security against unwanted opening of the bag. Please note: Bean chairs purchased without a removable liner are constructed differently to a bean chair purchased with a liner. This means that you can not buy a liner in the future as the liner and the chair will not be compatible.
