Rebo are always listening to their customers' ideas, and we were excited to develop a new monkey bar range to add that extra fun element customers were looking for! Constructed of pressure treated timber, the 90mm top beams provides maximum strength, combined with 70mm legs to ensure children stay safe at all times. NOTE: Constructed of natural wood which can split or crack. This does not affect the structure or strength of the item. Even if there are cracks in the wood on delivery, this is completely normal and will not affect the strength and durability of the product. Warning: We recommend small children are supervised by an adult at all times while on play equipment and you allow a safety perimeter. Tools including a drill are required in the assembly of this product.
