Meet the next generation of playpens: The Bugaboo Stardust was designed with patented aerospace technology to pop open and fold back up in seconds, mattress included. The streamlined design features easy-clean fabric and mesh panels for airflow, and it's lightweight enough for easy transport in the included travel bag. It's both great for newborn naps with the zip-in bassinet, and sturdy enough for rough-and-tumble toddlers.
