What types of super king mattress are there?
Memory foam super king mattresses
Memory foam 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. They mould around your sleeping position, ensuring optimal support throughout the night.
Pocket Spring super king mattresses
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 body weight and prevent ‘roll together’ between sleep partners.
ActiGel® super king mattresses
Featuring a gel layer, super king ActiGel mattresses are great for regulating body temperature as well as responding to your movements and sleep position.
Zip and link super king mattresses
With a zip and link mattress, you can combine two smaller mattresses to make a super king, perfect if you and your partner have different comfort grade preferences.
Latex super king mattresses
With a naturally sourced latex layer that responds directly to your movements and sleep position, a super king latex mattress offers great support.
Natural super king mattresses
For those conscious about environmental impact, choose a super king natural mattress. These are crafted from natural materials such as wool and Egyptian cotton for temperature-regulating and breathable properties.
Traditional spring super king mattresses
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.
Choosing the best super king mattress for you
Finding the most suitable super king size mattress will largely depend on your sleeping position:
If you sleep on your side, you may want to consider a soft or medium comfort grade super king mattress. These softer mattresses offer essential support, easing pressure on joints during sleep. For those who shift positions regularly while they snooze, a medium comfort grade is typically a better choice.
If you tend to change sleeping positions a lot during the night, a super king memory foam mattress may be the one you need, as it will mould to your body shape quickly, no matter the sleeping position, so you remain comfortable.
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 super king-size mattresses distribute your body weight more evenly than a softer mattress, helping to relieve pressure and offer added support for your spine and joints. A firm or very firm pocket spring mattress may be a good option, 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 100-Night Sleep Guarantee gives you the option to swap your mattress for another after 30-100 nights of use (T&Cs apply).
