As my 5 Monte-old son is with the parents' bed often, I have attached the grid it! So I have a much better feeling when time is yet with us in bed. The attachment was super simple and has even worked in our pretty thick mattresses. That with the fold folds I do not think so really, I do not need this feature as well. I have the grid mounted near the top, so you can get into the bed side still great. The small is always higher than myself, so nothing can happen! Since the middle part is a "Belüftungsnetzt" I find the grid even better, because even if he sometimes slips before because with the face, it can get enough air! Optical (in blue), it is not a beauty, but that's not the point! I'm very satisfied with it!
