Memory foam super king mattresses are made from visco-elastic materials which respond directly to pressure points and react to heat with their open-cell structure. When in contact with your body, the mattress will start to soften and mould around your sleeping position, ensuring the very best in support and comfort, all night long.
Pocket spring mattresses have springs that respond independently to your movement to provide a comfortable and supportive night’s sleep. They also help to evenly distribute your bodyweight and prevent ‘roll together’ between sleep partners.
Featuring a gel layer, super king ActiGel mattresses are great for regulating body temperature as well as responding to your movements and sleep position.
Do you and your partner have different comfort grade preferences? Well, you don’t need to compromise, because with zip and link, you can combine two mattresses in one.
With a naturally sourced latex layer that responds directly to your movements and sleep position, a super king latex mattress offers great support.
For those conscious about environmental impact, choose a natural super king mattress. These are crafted from natural materials such as wool and Egyptian cotton for temperature-regulating and breathable properties.

One of our most cost-effective options, traditional spring mattresses are great for those who want comfort at great value – they’re especially popular for use in guest bedrooms.
With such a wide range of types and comfort grades available, it can be difficult to choose the best super king mattress for you. Finding the most suitable one will largely depend on your sleeping position:
If you sleep on your side, you may want to consider a Soft or Medium comfort grade mattress. These provide the cushioning needed while sleeping in this position as it alleviates pressure that builds up on vulnerable joints. If you tend to change your sleeping position, a medium comfort grade is usually most suitable. Perhaps consider a super king memory foam mattress as this will mould to your body shape, no matter position you’re sleeping in.
If you tend to sleep on your front or back, a Firm or Very Firm mattress is probably the most suitable comfort grade for you. These sturdier mattresses distribute your body weight more evenly than a softer mattress, helping to alleviate pressure and providing the extra support needed for your spine and joints. A firm or very firm pocket spring mattress may be a good option here, providing extra spinal support for a comfortable night’s sleep.
Choosing a super king size mattress is an important investment – one that’s going to last for years. That’s why we want to make sure you get the very best option for you. Our 40-Night Sleep Guarantee gives you the option to swap your mattress for another after 30-40 nights of use (Ts & Cs apply).
