A playpen includes a plurality of support bars, a bed cushion, and a fixing device to fix the bed cushion on the support bars. Thus, the snapping plate of each of the holders of the fixing device is locked on the respective positioning seat, and the sleeve of each of the holders of the fixing device is locked on the respective support bar by the locking, so that each of the holders is positioned on the respective positioning seat and the respective support bar so as to support the bed cushion rigidly and stably, thereby preventing the bed cushion from becoming loosened or detached from the playpen.
