Is a 140x220 cm mattress wide enough for two people?

A 140x220 cm mattress gives each person 70 cm of space, which is workable for couples who sleep close together but limited for restless or broad-shouldered sleepers. For couples who prefer more personal space, a 160x220 cm mattress is the better choice, as the extra 20 cm in width gives each person 10 cm more room. The 140x220 is at its best as a generous solo mattress for tall sleepers or as a shared bed for couples who prioritise length over width.
