Abstract: An infant seat for use in a number of environments including shopping carts, pre-school nurseries, and other uses is disclosed. When used with shopping carts, the infant seat includes a contoured bucket seat which has a substantial portion that is supported within the confines of a shopping cart with an infant positioned to face a user of the shopping cart. The contoured bucket seat is capable of being pivoted substantially outside of the confines of the shopping cart to facilitate nesting of adjacent shopping carts within the respective confines of each other. When used in a pre-school nursery environment, the infant seat is adapted to be mounted on a supporting structure. In other environments, the infant seat may be used by itself. The contoured bucket seat forming the infant seat is integrally formed from a closedcell flex foam material which provides substantial strength and durability while also being soft enough to enable an infant to be comfortably positioned within the contoured bucket seat.
