Since our son was getting mobile and gemeinsan sleeps with us in a bed, had a bed rail ago, so we reassured parents can continue to sleep when Junior is active at night. The bed rail from Hauck is easy to assemble and install the bed is very simple, as it is pushed just under the mattress. Optionally you can also hook the grid with tension belts on the opposite side of the slatted frame. The grid is also sufficiently high. In our mattress height of about 22cm, it is high enough that it can not be so simply crawling overcome (what it looks like when Junior starts to pull himself up remains to be seen). By comparison, the Safety1st bed rail fall which we have also, in spite of similar altitude in the item description, considerably lower from. the foldover function, we can not use because of the bed frame (Ikea Malm) is too high - but that does not continue. I highly recommend the purchase of the grid.
