The material is nice and solid. Even the baby in it feels comfortable. BUT: 1. Contrary to the description, you can not build alone the bed. The lying area must be set horizontally with a spirit level and then fixed from both sides simultaneously. Was also for two not very easy. 2. I had to fix the crib to the upper edge of the bed, so at the height of the lying surface of the bed, with the result that I could not install the associated closure grid. Docking to the parents' bed and closing grid (for the siesta during the day) is not at the same time, and switch the back and forth requires a lot of work, because the docking system is characterized not just by easy handling ... if you can dock from the bottom of the big bed, should not be a problem. 3. The shutter grid is easier to install (but not so that the baby is not growing), but then the mattress is (also original of BabyBay) too big, and you have to press and squeeze to anzubrigen the grid. Then baby has finally awake. 4. The crib should be able to use as a children's table later. Only the tabletop (formerly lying surface) has holes. For the breathability of the mattress an advantage clearly detrimental to a tabletop ... Conclusion: everything a great idea, unfortunately not optimally implemented, so that one of them has, less than expected ... I would have given 2.5 stars, I'm really satisfied only half.
