What size is a super king mattress?

Sitting at the very top of the standard UK mattress sizes, a super king mattress size measures 6 foot wide by 6 foot 6 inches in length, or 180cm by 200cm. All super king mattresses available at DFS will fit our super king size beds. You just need to be mindful of the height of the mattress - this does vary, and some extra thick mattresses will peek above the ends of lower footboards, which might not be the look you’re going for.

Which super king size mattress comfort is right for me?

It really depends on your personal preference - some people prefer a softer super king mattress, while others prefer the support of a firm super king mattress. We stock super king size mattresses at all firmness levels, including soft, medium soft, medium, medium firm and firm. Once you’ve settled on your firmness level, there’s also the type of mattress to think about - our range includes pocket sprung, gel, foam, open coil, hybrid and memory foam super king mattresses.

How much is a super king size mattress?

You can expect to pay between £400 and £3000 for a quality super king mattress - with the mattresses at the top end of the scale performing best for lasting support, temperature regulation, movement isolation and more. Don’t forget - a quality super king size mattress will last you many years, so it pays to choose the best you can afford. For extra peace of mind, all our super king mattresses at DFS come with a minimum of a 2 year guarantee, with some carrying up to a 7 year guarantee.

Can I use my new super king size mattress straight away?

Generally, yes, you can use your super king mattress the same day it is delivered. Most manufacturers recommend unwrapping and situating your mattress on your bed frame, and then leaving it for a few hours before covering with your bed linens and sleeping on it - this is because it will both allow the fillings to expand or settle into place, and give time for any box-fresh odours to dissipate, which is perfectly normal with most kinds of upholstered furniture. Some types of mattresses, like rolled super king mattresses, take a few more hours to expand fully after unwrapping, as they have been rolled tightly for ultra-convenient transport.
