A child seat includes a seat portion fixedly connected with a first coupling part, a connector that is pivotally connected with the first coupling part of the seat portion and is operable to detachably engage with a corresponding structure provided on a child supporting apparatus, a locking mechanism operable to lock and unlock the connector with respect to the seat portion, and a backrest frame fixedly connected with a second coupling part and operatively connected with the locking mechanism, the second coupling part being pivotally connected with the first coupling part, wherein the backrest frame is rotatable in a folding direction to cause the locking mechanism to unlock the connector with respect to the seat portion and in an unfolding direction to cause the locking mechanism to lock the connector with respect to the seat portion.

A portable bleacher seat designed to restrain a child sitting in a bleacher. The portable bleacher seat has a folding seat with a seat member and a back member. The seat member is a rectangular prism with an upper surface opposite a lower surface and a front side opposite a rear side, with a fastener on the lower surface designed to secure to a bleacher. The back member is pivotally connected to the rear side of the seat member and can selectively pivot between a closed and open position. The back member is perpendicular to the seat member when in the open position. A tray is removably affixed to the folding seat with a gap created between the tray and the folding seat. The gap is configured to receive a child therein. In this way, a user is able to restrain a child at an event with bleacher seating.

An entertainer for a child that is specifically configured and adapted for use in several operational configurations. The entertainer includes a plurality of legs and a tray for supporting a plurality of activity items for the child. A multi-functional plate is attachable to the legs to allow the entertainer to assume a seat support configuration. The multi-functional plate is detachable from the legs and positionable over the tray to allow the entertainer to assume a table top configuration.

A collapsible convertible highchair and infant carrier stand device is provided. It includes basket and a base supporting the basket. The basket is configured to receive an infant carrier or to directly support a seated infant. The basket includes a bottom wall, a first end wall, a pair of sidewalls, a second end wall, a crotch panel and a back support panel. The crotch panel and the back support panel are located in the basket between the first and second end walls. Each is configured to be pivoted from a stowed position, when the device is holding an infant carrier, to an operative position when the device is directly supporting the infant. In the operative position the infant's back will rest against the back support panel and his/her legs will extend through opening in the crotch panel and a window in the first end wall.

The convertible child high-chair and step stool can include a frame having a front leg stand and a rear leg stand. A height adjustment mechanism can be coupled to the front leg stand or the rear leg stand and can be adjustable along the vertical axis of the front leg stand or the rear leg stand from a raised position to a lowered position. The apparatus can also include a booster seat and removable platform step. In the raised position, the booster seat can be coupled to the height adjustment mechanism to provide a high chair. In the lowered position, the booster seat can be removed and the removable platform step can be coupled to the height adjustment mechanism and the frame to provide a step stool. The apparatus can also include wheel assemblies coupled to the frame that limit the potential for tip hazards in the step stool configuration.

A foldable chair includes a main plate and a support plate. The support plate is hinged along a first rim to a rear side, along a central, longitudinal, top-down, axis, of the main plate. The main plate has a seat plate and a foot-rest plate each hinged along an upper edge to the main plate in corresponding apertures of the main plate. The support plate includes bracket portions extending, in the plane of the support plate, from the first rim, in each corresponding position corresponding to the apertures, for pushing the plates up to an operative position and supporting each of the seat plate and the foot-rest plate in an unfolded, operative, position when the plane of the support plate is arranged perpendicular to the plane of the main plate.
