Why I have given four stars. I find it difficult to give a 100% good evaluation. the first travel cot from Hauck we bought 4 years ago. After about a quarter of the material began to travel and go to the näte. I was shocked. Hauck's a brand and I was deeply shocked. But I had guaranteed. I signed up at amazon and without problems they've the bed exchanged. As always Aazon is great in these matters. The new bed came and I was still skeptical. Now it's been 3 and a half years in Using 'and still in top shape. Maybe I was just unlucky with the first bed. On the whole, I am again convinced but it is still not enough for 5 stars.
