King Size Mattress FAQs

Have a different question? Read our handy
mattress buying guide.
A king size mattress is a very generous 150cm wide and 200cm long. The extra wiggle room is perfect for couples who like a little more space, or for one person who wants superior comfort.

Different bed frame sizes suit different sized bedrooms. If you are lucky enough to have a large bedroom, choose king size to make a statement without drawing all the attention away from the rest of the room.
A king size bed is W150cm x L200cm, meaning there’s plenty of room to stretch out and get comfortable. Elevate your interior with our range of stylish and spacious bedframes, featuring everything from wooden to contemporary finishes.
The main difference in the size of the beds is the width. A king size mattress is smaller at W150cm x L200cm and a super king size mattress is bigger at W180cm x L200cm. This extra width can be great for couples who prefer some space to stretch out in bed.
