It's an air trampoline. I've used it 2-3 times, but it's too big and my room got cramped, so I'm selling it. It comes with an automatic air pump, so it's easy to inflate! It's for indoor use, and the sides are enclosed, so even small children can play safely. There is no outer box, so I will ship it in a cardboard box. ● A trampoline for fun indoor play. ● You enter from one entrance, and it's surrounded by high walls, so you can play in it like a secret base. ● Weight capacity: 54kg (Up to 2 children can play at the same time) ● Product size: (approx.) 112 x 174 x 174cm ● Product weight: (approx.) 8.14kg ● Material: Vinyl chloride resin (using non-phthalate plasticizer)
