Each booster set comes with one larger booster and one smaller booster.
Use the smaller booster alone for newborns, then move on to the larger booster and finally use both together for overnight or for heavy wetters.
Both boosters have a bamboo fleece core with a suede cloth top, keeping little ones skin dry. Each booster has handy snaps to secure it into the shell.
The larger booster also features a waterproof back to protect the shell.
