A youth seat reclining mechanism is located inside the youth seat bottom to rotate the youth seat footrest via rotation of the youth seat backrest simultaneously driven by reclining of the booster seat backrest.

A convertible child chair converts between multiple heights, including a high chair, a child seat, and a booster seat, through simple reconfiguration of a leg assembly of the chair. A belly band may be removably coupled to a seat of the child chair. A tray may be removably coupled to the child seat and may have an adjustable depth while remaining coupled to the chair. A footrest may be removably coupled to the chair and may have a adjustable height by removing the footrest and flipping the footrest.

A high chair structure is disclosed. In the disclosed high chair, an upper tray board is elastically fixed on a tray assembly of a seat part thereof. In addition, two fixing-belt receiving grooves are disposed on two sides of the seat part, and two cover boards are disposed on the openings of the fixing-belt receiving grooves to cover thereon. Moreover, the high chair further comprises a desk part that can be separated from the seat part, so that the desk part can be used as a desk alone.

A child restraint seat includes a seat unit, a locking mechanism and a releasing handle. The locking mechanism is disposed on the seat unit and adapted to fix the seat unit onto a first external structural unit. The locking mechanism includes a latch base disposed on the seat unit, a first latching component movably disposed on the latch base, and a lock releasing component connected to the first latching component. The first latching component is adapted to move relative to a first constraining component of the first external structural unit for switching between a closed position and an open position. The releasing handle is disposed on the seat unit and connected to the lock releasing component, the releasing handle is utilized to drive the lock releasing component to move the first latching component from the closed position to the open position.

A child seat includes a seat body, and a first and a second support respectively assembled with the seat body via a first and a second connection. The seat body has a seating surface and a bottom surface below the seating surface, and the first and second support are extendable below the bottom surface. The child seat has a first configuration in which the first support is configured as a leg resting board and the second support extends forward toward the first support, and a second configuration in which the first support is folded to a substantially horizontal position and the second support extends rearward so that the child seat is able to stand on the first and second supports.

A convertible highchair assembly includes a seat frame, a booster seat detachably installable on the seat frame, a tray detachably mountable on the booster seat and having a plurality of sockets, and a plurality of leg extensions selectively attachable to any of the support frame portion and the tray, each of the leg extensions having a connecting end. The seat frame includes a support frame portion and a seat portion affixed with each other, the seat portion being adapted to receive a child. The connecting ends of the leg extensions are attached to the support frame portion for configuring a highchair, and the connecting ends of the leg extensions are respectively inserted into the sockets while the tray is removed from the booster seat for configuring a standalone table, the leg extensions providing standing support for the tray.
