What is the difference between a 140x190 and a 140x200 cm mattress?

A 140x190 cm mattress is 10 cm shorter than the standard 140x200. Those 10 cm in length can make a meaningful difference in smaller rooms, and the 140x190 is the right fit when an existing bed frame requires it or when saving floor space is a priority. For sleepers taller than 170 cm, the 140x200 is the safer choice to ensure full-body support.
