The QUADRO CLIMBING PYRAMID is a Giant Construction kit with a total of 236 parts. There are a variety of different model designs which will provide years of fun indoors and outdoors.
Not the cheapest but supposed to be pretty indestructable. Made in Germany and lots of add on bits and pieces that you can get to expand it.
Age range for use as a climbing frame looks to top out around 8 but reports of making models / furniture / cars (with he wheel add ons) etc after then.
I’m sure I’d seen this deal on HUKD a while back and it went out of stock but can’t find it anywhere. Back in stock atm now anyway.
