Abstract: A child booster seat assembly includes a base seat, an upper seat and a latch mechanism. The upper seat is detachably installed on the base seat. A first guiding structure and a second guiding structure are formed on the upper seat and the base seat respectively and for cooperating with each other to guide the upper seat to be aligned with the base seat. The first guiding structure protrudes from a rear bottom portion of the upper seat. The latch mechanism includes an actuator movably disposed on the upper seat, a first engaging structure and a second engaging structure. The first engaging structure is movably disposed on the first guiding structure and connected to the actuator. The second engaging structure is formed inside the second guiding structure and located at a position corresponding to the first engaging structure for engaging with or disengaging from the first engaging structure.

Abstract: A child booster seat assembly includes a base seat and an upper seat. A first seating area is formed on the base seat. The upper seat is detachably installed on the base seat. The upper seat can be installed on the base seat installed on an adult chair at a higher position or detached from the base seat and installed on the adult chair at a lower position, which allows a caregiver to adjust an elevated height of the upper seat easily. Furthermore, when the upper seat is detached from the base seat, the upper seat and the base seat can be used independently and respectively installed on two adult chairs for accommodating two children at once.

Abstract: A child stroller system can convert from carrying a single child to carrying two children without removing a first child-carrying apparatus from the stroller and without adding adapters to the stroller. Both child-carrying apparatuses can be repositioned with respect to the stroller's chassis when mounted on the stroller. A self-standing and collapsible auxiliary basket can be mounted on the stroller in place of one of the child-carrying apparatuses.

Abstract: In one example, a carrycot couples to a support frame to support the carrycot above a support surface. The carrycot has a carrycot frame having a first side and a second side that are spaced from one another so as to define a space therebetween that supports a child therein. The carrycot has a set of attachment features that is disposed at the first side and removably attaches to a bayonet of the support frame. The set of attachment features includes (1) a bayonet receptacle that receives a first portion of the bayonet and (2) a plunger that is spaced below the bayonet receptacle with respect to a vertical direction and is configured to engage an opening in a second portion of the bayonet.
