Here comes another great idea from Our Children's Gorilla. We are loving Scullcave, a portable play hut for kids (or anyone who can reasonably fit inside).
Scullcave is made of a Sensaten, a durable and lightweight material used when laying the foundation of cemented roads. The play hut measures 90 x 100 CM when assembled. When play time is over, simply roll it up and thrown him in a drawer.
It's available here for $271.
