A stroller includes a base frame assembly and a seat assembly supported by the base frame assembly. A seat leg extending from the seat assembly is slidably engaged with the base frame assembly for movement of the seat assembly relative to the base frame assembly from a first seating height level to a second seating height level. In some cases, a support post of the base frame assembly is oriented in a telescopic arrangement with the seat leg along a generally vertical axis. In some cases, one or more slider mechanisms slidably couple the seat assembly to the base frame assembly, where each slider mechanism has a lock to secure the seat assembly at either the first seating height level or the second seating height level.
