This pop-up play tunnel from Kid's Concept opens in seconds and folds flat for compact storage in the included carry bag. This portable crawl-through tube can be used on its own or attached to a pop-up tent to create a playful hideaway for crawling, rolling games, or quiet reading time. This lightweight activity tunnel is made with durable polyester, a spring-steel frame and polypropylene trims, designed for indoor use on smooth floors and suitable for children aged 2 and up. This fabric is not treated with flame retardants, so keep the tunnel away from heat sources and open flames for safe play.
