A booster seat for children, comprising a seating surface adapted for engagement with the seating surface of an adult chair, a backrest, at least one pair of wings connected to the bottom side of the seating surface and designed to be angularly moved between a first position in which they are oriented parallel to the bottom side and a position in which they are lifted and oriented at an angle relative thereto, as well as a plurality of flexible elements for removable fixation of the booster seat. The seating surface of the booster seat comprises, on its rear side, at least one compartment formed below at least one of the wings, for which the wing forms a closing cover.

The present invention relates to a high chair for children convertible into a booster seat comprising an upper part and a base, the upper part having a seating surface adapted for engagement with a corresponding bearing surface of the base, lateral armrest sides, a backrest whose perimeter boundary extends from one lateral side to the other, as well as a backrest extension extending in cantilever fashion from the perimeter boundary of the backrest.

The backrest extension consists of a body separate from the backrest and comprises members for removable connection to the perimeter boundary of the backrest. When the backrest extension is removed, the upper part of the high chair is used as a booster seat.

A booster seat includes a storage compartment for a tray and/or a storage compartment for securing straps. The tray-storage compartment can be formed in a base of the seat and include an access opening through a sidewall of the base. The tray-storage compartment can include two opposite and inwardly-extending lips that support the tray in the stowed position, and a support foot that moves between a use position in the compartment where it helps support the seat and a stored position displaced from the compartment. Also, the tray-storage compartment can include ribs that engage the tray in the stowed position to retain it there. The strap-storage compartment can be formed in the base and include an access opening with a closure for retaining the straps in the compartment. A base panel can be provided for stability and support.

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 booster seat includes a storage compartment for a tray and/or a storage compartment for securing straps. The tray-storage compartment can be formed in a base of the seat and include an access opening through a sidewall of the base. The tray-storage compartment can include two opposite and inwardly-extending lips that support the tray in the stowed position, and a support foot that moves between a use position in the compartment where it helps support the seat and a stored position displaced from the compartment. Also, the tray-storage compartment can include ribs that engage the tray in the stowed position to retain it there. The strap-storage compartment can be formed in the base and include an access opening with a closure for retaining the straps in the compartment.

A child booster seat includes a base, a flexible connecting member, two attachment parts, and a mechanism. The base has a seat plate for a child sitting thereon. The flexible connecting member is attached to the base. The attachment parts are attached to two ends of the flexible connecting member. The mechanism is disposed on the base for tensing the flexible connecting member. When the child booster seat is secured on a chair through the two attachment parts, the mechanism is operated to tense the flexible connecting member, so that the child booster seat is secured firmly and it is hard to move the child booster seat relative to the adult chair.
