A foldable playyard combined with an outer playyard frame assembly and an inner playyard frame assembly is disclosed. The outer playyard comprises an essentially rectangular upper support composed of four pairs of rail sections each centrally coupled by a switch unit, each pair of rail sections being pivotably connected to a respective corner bracket provided at four corners of the upper support, a lower support respectively engaged with four vertical rails at a lower end. The lower support includes four legs, each for receiving a corresponding vertical rail, four tilting rails sections each pivotably coupled to one of the legs at one end thereof, two pairs of curved L-shaped rail sections, each respectively coupled with the other ends of two adjacent tilting rails by a hinge and pivotably attached to each other at a different end and two posts each disposed under one of the hinges and supporting the corresponding hinge, providing a stable lower support structure. The inner playyard has four corner bearers each releasably gripped to a corresponding corner bracket and four vertical short rails each integrally formed beneath a corresponding corner bearer to provide a height-adjustable structure.
