King Size Bed Mattress
Welcome to our king mattress collection, where we offer a terrific range of mattresses across all feels, types and price points.
A king bed mattress is nothing short of a dream! With so much space, this mattress allows plenty of room for both sleepers to really stretch out and enjoy every square inch. A king-size mattress calls for a generously sized room. You would ideally need a space of at least 3.5M2 (which also allows for bedroom furniture).
What size is a king mattress?
Customers regularly ask us how big is a king-size mattress? The answer is 1830mm x 2030mm.
Is a king size bigger than a double bed mattress?
Absolutely - it is significantly bigger than a double mattress. A double mattress is only 1370mm x 1880mm. In fact, nothing is larger than a king mattress size other than a super king mattress.
Are king mattresses different sizes?
No - here at OMF all our mattresses are standardised, so you can expect these dimensions of 1370mm x 1880mm no matter which model you select. Don’t confuse this with a super king mattress or king single mattress!
