Background
Many booster seat products currently on the market are sold as booster seats with removable backrests, which can be converted to booster seats without backrests as children grow. Over the years, there has been an increasing legal age requirement for children to sit on booster seats, and current booster seats are suitable for children of the age of 10. At age 10, the child may be taken by a different caretaker. For example, one parent may be presented to a child for school, while another caretaker may be presented to the child for school. Existing booster seats are typically large and cumbersome, which makes it difficult for a child to carry the booster seat or requires a caretaker to purchase multiple booster seats.
In addition, many child booster seats and convertible seats currently on the market are sold with storage shelves such as cup holders and/or snack holders. The shelf typically extends beyond the width of the seating surface, resulting in a seat having an overall width that is greater than the width of the seating surface.
