King Mattress

The King Mattresses offers generous space for both sleep and play. It's 14 centimetres wider than a queen mattress - giving the best undisturbed sleep for couples. It's hard to go wrong with a size this huge.


Space begets space! Since the king mattress is roomy, it needs a spacious room to house it in. King mattresses require quite a sizeable room of at least 11-12 square metres.
