What is the difference between a 140x200 and a 140x210 cm mattress?
A 140x210 cm mattress is 10 cm longer than the standard 140x200. For sleepers taller than 185 cm, those 10 cm mean the difference between lying fully supported and feet pressing against the end of the mattress. The 140x210 gives taller sleepers the length they need without having to step up to a wider format.
