From year to year at beaches and pools, there are more and more air mattresses, boats, and of late imaginative inflatable animals of fiery colors and impressive looks, for which all generations are sighing. All these inflated toys make the hours of relaxation at the beaches and pools more pleasant. But most often we inflate them once, transport them maybe two or three times to the beach and then move them from one room to the other, where they are less in the way, until the end of the summer.
