Mattresses received quickly, French manufacture, with a summer side and a winter side for a really cheap price. The actual dimensions correspond, it does well 120x60 and 11cm thick. The winter side has good reasons made by the seam as in the photo, the face was completely even and smooth. It is neither too soft (phew!), Nor too firm. It is packed in a cardboard cube-shaped, bent double in a plastic film. I installed it in a bed 120x60 Trama and even if the dimensions of this mattress are as 120 x 60, I find that there is still not a lot of head or foot of the bed space (mattress good touch wood in this sense) but on the sides: there has an area of 3.5 cm 3 see each side (so that's a total of 7 cm to fill with a rolled towel on one side if one has lest 3.5cm making a vacuum on each side present a danger to the child ... it stuck an arm or a leg .. I have another Trama bed with a mattress 120 x 60 Aubert (120) and I do not have this problem .. Peut.être product is better has a cot? Otherwise, it's a good mattress, baby sleeps there like a king!
