Super King Traditional Spring Mattresses

While our super king mattresses are chosen with value in mind, traditional sprung models take the ethos of value for money even further. The simple design comes without the bells and whistles of the more advanced models without losing any of their effectiveness and levels of quality.

Super King Firmness Levels

Our super king mattresses come in all the firmness levels you could imagine. When choosing the ideal mattress for you, comfort grading is equally as important as the style or design. Pairing up with the correct firmness is straightforward. Understanding your sleeping position and match it to the firmness level you need for optimal pressure relief and comfort.

If you tend to sleep on your side or are light in body weight, a soft super king mattress will give you adequate cushioning on those all important pressure points. Alleviating a build up of pressure, the soft tension evenly spreads body weight as you sleep, preventing any unnecessary pressure being placed on hips and shoulders.

If you toss and turn during the night and sleep in a variety of positions, medium super king mattresses will provide the best of both worlds. Designed with a modicum of cushioning and adequate firmness, this comfort grading is ideal for partners who have different sleeping preferences.

Those who sleep on their stomach or back should choose a super king firm or extra firm mattress for enhanced durability and firm support. The added firmness focus on the spine, promoting a healthy alignment to soothe back pain and help in getting a pain free nights sleep. This level of firmness is also best suited to heavier individuals due to the extra support and lack of cushioning.
