It's a modular climbing wall for the nursery! This sturdy indoor climbing wall consists of two triangular modules, each with 9 pre-drilled holes for the 6 included climbing holds made of durable plastic. The holds can be positioned as needed and adjusted to suit the needs and size of the children. It comes with cutouts to protect wall surfaces when mounted on the wall; wall mounting hardware not included. This climbing wall transforms any nursery into an indoor climbing playground! The climbing blocks are easy for children to grasp and can be easily moved on the shelves as needed without having to remove the shelves from the wall, as all mounting holes are threaded. It can be flexibly expanded: with one or more sets, you can create your own climbing worlds (e.g., a ridge), depending on how much wall space is available. It is compatible with and expandable with the "Adventure" climbing blocks. A fun motor skills training session is included!
