The mattress itself is ok. However, the actual extent of the mattress 67 x 97 cm. The specified 75 x100 cm refer to the outer dimensions of the playpen. This was also confirmed to me directly from the manufacturer and they wanted Träumeland clarify the description in Amazon accordingly. Since the mattress support (!) Of our playpen is 75 cm wide, it was too small and we sent them back. (We now have the mattress with proven 80 x 102 cm made, which is actually 75 x 97 cm in size. This was recommended to me also by the manufacturer).
