I have 2 grids à 11 bars added sand. Whether this is an error or the manufacturer / supplier has now touched up, I do not know. I am certainly very pleased. Due to the recession concerning. The durability I was a little critical in advance. But so far I can say that keeping the bars. Mich 80kg (for the goodnight story) and children (for the bed so ultimately is) anyway.
For extra product delivery is there from me 5 stars! (I forgive rarely 5 star, but here they are earned!)
