What is the difference between an 80x190 and an 80x200 cm mattress?

An 80x190 cm mattress is 10 cm shorter than the standard 80x200 and fits in a more compact footprint in both length and width. For sleepers taller than 170 cm, those 10 cm less in length mean feet can reach the end of the mattress, which affects posture and sleep quality. The 80x190 is the right fit when a specific bed frame requires it or when saving floor space is the priority; for most adult sleepers, the 80x200 gives more comfortable headroom.
