What is the difference between a 160x190 and a 160x200 cm mattress?

A 160x190 cm mattress is 10 cm shorter than the standard queensize 160x200. For sleepers taller than 185 cm, a 160x200 is more comfortable; a 160x190 provides sufficient support for most people but can feel short for taller sleepers. The 160x190 is the right choice when an existing bed frame is built to 190 cm internally, or when saving those 10 cm in a smaller room makes a meaningful practical difference.
