That's the Mercedes under the mattress

The mattress is super great soft and my little one is sleeping as well in it. We are absolutely satisfied. However, it is very thick, which has led us to the fact that the one and a half year-old son of my friend had to sleep with the rust / and mattress on the floor and not on the lowest floor of the lattice bed. Since the mattress is so high he could climb out easily. Basically, that's no problem, but to me it was not previously aware. There are probably thinner mattresses. Regret buying but in no event may the mattress and a friend like.
