A foldable mechanism is applied to locking an infant carrier and includes first and second mounts and a locking member. The second mount is pivoted to the first mount and has first and second mating portions. The locking member is movably disposed between the first and second mounts and is movable along an axial direction of a rotating axis of the first and second mounts to lock and release rotation of the first mount. The locking member has a positioning portion and a locking portion. The first mount is locked at a first rotating position or a second rotating position via movement of the locking member. The positioning portion is engaged with the first mating portion to lock the first mount at the first rotating position. The locking portion is engaged with the second mating portion to lock the first mount at the second rotating position.

A seat assembly comprises a booster seat with a lower support surface and an upper seating surface. A back support extends upwardly at the rear of the upper seating surface and side supports extend from the back support around the lateral edges of the seating surface to merge with the upper seating surface. A supplementary base has a peripheral edge to engage the periphery of the lower surface to provide increased lift. The base has an aperture dimensioned to receive the back support and side supports so that the base may be inverted and nested on the upper seating surface.

In one example, a highchair has a seat and a base. The base is attached to the seat such that, when the base is disposed on a surface, the base supports the seat above the surface. The base has a plurality of legs that are rotatable so as to transition the highchair between a raised position and a lowered position. In the raised position, the seat is disposed at a first height and the plurality of legs together define a first footprint that has a first cross-sectional area in a select plane. In the lowered position, the seat is disposed at a second height, lower than the first height, and the plurality of legs together define a second footprint that has a second cross-sectional area in the select plane that is less than the first cross-sectional area.

A convertible furniture and toy assembly for children, which has a symmetrical base unit and replaceable module elements that can be attached thereto. The base unit contains two side units arranged at an equal distance from its plane of symmetry and at least two connecting elements connecting the two side units. The convertible furniture and toy assembly for children is provided with a stabilizing system in which the side unit of the base unit contains a first side element, a second side element, and an intermediate side element connecting them. The first side element is arranged at a predetermined distance X and the second side element is arranged at a predetermined distance X+Y+V from the plane of symmetry. The stabilizing system preferably also contains at least one connecting member and module elements that can be installed symmetrically on the base unit.

A children's dining chair includes a base, handles, and a backrest. A left side, a right side, and a rear side of the base are provided with blocking walls. A first storage slot is defined in the blocking walls. The handles are detachably arranged on the left side and the right side of the base. The backrest is detachably arranged on the rear side of the base. When the handles and backrest are disassembled from the base, the handles and the backrest are capable of being stored in the first storage slot.
