Choosing the right size

Which size should I choose?

If you sleep alone, choose Single or Small Double. For couples, Double or King. For extra space, King or Super King.

Sleep alone

Single is compact and practical. Small Double gives more movement space.

Buying for a couple

Double works for smaller rooms. King is the preferred upgrade for everyday comfort.

Want extra room
