Trampoline tent. This tent fixture ($`250, plus delivery from the UK) clips onto the edge of a circular trampoline, converting it into a tent or backyard playhouse for kids. It features four windows and two zip-up doors, and comes with a waterproof fly sheet. This is so cool.
Canvas A-Frame Tent- this pin connects to a catalog to order these genius tents! This is the kind of "toy" worth spending $ on- it would provide hours of play and last for years. If you are very handy you could make your own- love how it also folds up!
