What is the difference between a 160x200 and a 160x210 cm mattress?

A 160x210 cm mattress is 10 cm longer than the standard queensize 160x200. Those 10 cm prevent feet and legs from hanging over the edge for sleepers taller than 180 cm, directly improving spinal support and sleep quality. The 160x210 is a standard format, not a custom size, so it carries no extra cost or longer delivery time.
