A storage system includes structure having a surface that at least partially defines a storage compartment. The structure also defines an opening through which the storage compartment is accessible. The storage system further includes a plurality of flexible protuberances extending from the surface into the storage compartment. At least some of the protuberances deform as an object is inserted into the storage compartment through the opening. The deformed protuberances conform to the shape of the object, thereby supporting and restraining the object within the storage compartment.
