What is a medium firm super king size mattress?

This mattress type is defined by its super king size, the largest standard UK mattress size, and a medium firm tension.

Considering a super king mattress

If your bedroom already features a super king size bed and you're just looking to replace the mattress, then a super king size mattress is the only compatible option. However, you may be looking to purchase a super king bed and mattress together. In this case, you should pay careful attention to whether your bedroom is large enough to accommodate a super king mattress and bed. For context, a super king mattress measures 6'0" wide by 6'6" in length, so it may be worthwhile measuring your bedroom to assess the suitability of a super king size mattress. Alternatively, double or king mattresses also represent spacious sleeping solutions and allow for greater room for bedroom furniture.

Considering a medium firm tension

Medium firm mattresses are recognised for their versatility and can support side sleepers as well as front and back sleepers. The medium firm tension is soft enough to sufficiently cushion the hip and shoulder whilst side sleeping yet is also firm enough to evenly distribute weight and promote healthy spinal alignment whilst front and back sleeping. The best super king mattress will remain consistently comfortable and supportive regardless of your sleeping position and pave the way for a restful night's sleep. If you solely sleep on your front or back, a super king mattress with a firm or extra firm tension is recommended. Essentially, your sleeping position should determine which mattress tension you opt for.

What mattress types does our collection feature?

We feature a range of super king size mattresses, all varying in composition and fillings, ensuring we cater to all sleeping preferences. Detailed below is an overview of our collection.

Open coil super king mattresses

Open coil mattresses are often deemed budget options; however, don't let the cheaper price point put you off purchasing an open coil super king size mattress. Our collection of open coil mattresses are supportive and comfortable, paving the way for an excellent night’s sleep. This mattress type consists of a strong and rigid steel coil wound into a continuous spring unit to form the mattresses core. 

Pocket-sprung super king mattresses

Our pocket-sprung super king size mattresses are fantastic if you're looking for a mattress that offers tailored support. Each spring is encased with a fabric sleeve and reacts individually to body movements to apply targeted support and relieve pressure.

Memory foam super king mattresses

Memory foam conforms to the body's contours and provides cushioned support. When pressure is applied to the mattress, the surface reacts to pressure points and moulds to the body shape. Memory foam and pocket springs are similar in that both mattress compositions provide a tailored sleeping experience and sumptuous comfort.

Gel foam super king mattresses

For all the benefits of memory foam, a super king memory foam mattress isn't recommended for anyone who often sleeps hot at night. This is because memory foam isn't breathable and absorbs body heat. If this applies to you, consider a gel foam option; a gel foam layer sits towards the top of the mattresses and offers a cool sleeping surface with similar body moulding properties that memory foam is recognised for.

Latex super king mattresses

Similar to gel foam, latex is excellent at regulating body temperature and is another viable alternative to memory foam options for anyone who often sleeps hot. Latex is derived from the sap of rubber trees and is a premium and exceptionally comfortable mattress choice. Compared to the 'sink in' sensation that memory foam possesses, latex offers more of a 'bounce-back' feeling, whilst latex's elasticity ensures excellent breathability.
