Walk on his playhouse? What a funny idea… And yet so much fun! We are not fooled, and we have been children too. Building is fun, but deconstructing is hilarious. So, in the heat of the action and according to some crazy ideas, the units could be (a little) mistreated. That’s why we chose these materials and why we did a lot of resistance tests. The answer is yes, your units can be savagely trampled. Be careful though, it is not excluded that, positioned in a certain way, in random balance, the units can slightly bend or even break, on a corner for example. The brutality of our toddlers is sometimes impressive, let’s be clear. So, walking on flat units, yes, on an unstable pile of overlapping units, preferably to be avoided.
