Super King Medium Open Coil Springs Mattresses

A medium mattress is often considered a universal comfort option, suitable for most people regardless of weight, sleeping position or preference. It offers enough support to keep the spine aligned and reduce pressure points while also providing enough cushioning to promote a night of comfortable and restful sleep.

An open coil spring is a type of coil spring made from a single wire coiled into a helical shape. Open coil mattresses are known for their affordability, durability, and ability to provide a medium-firm level of support. They also tend to be lighter and easier to manoeuvre than other mattresses.


Shop mattresses from big brands including Sleepeezee, Silentnight and Giltedge. Choose from pocket spring, memory foam, hybrid and natural fillings options, available in every UK size. Selected mattresses include a 60-night trial, with free next-day delivery on orders over £299 and removal of your old mattress if required.

Mattress FAQs
Everything you need to know before you buy
What mattress firmness is right for me?
Firmness depends on your sleep position, body weight and personal preference. Side sleepers generally suit a softer feel as it cushions pressure points at the hip and shoulder. Back sleepers do best with medium to medium firm — enough support to keep the spine aligned. Front sleepers need a firmer surface to prevent the lower back dipping. Heavier sleepers tend to need a firmer mattress as they compress the layers more.
How long should a mattress last?
Most mattresses last between 7 and 10 years with proper care. Higher quality pocket sprung and latex mattresses can last 10 to 15 years. Signs it's time to replace yours include visible sagging or lumps, waking with aches and pains, or simply not sleeping as well as you used to. Rotating your mattress regularly helps extend its life significantly.
What's the difference between pocket sprung and open coil?
Open coil mattresses use a single connected wire system — less expensive but more prone to motion transfer. Pocket sprung mattresses have individual springs each sewn into their own fabric pocket, so they respond independently to movement and weight. This means better support, less partner disturbance, and a longer lifespan. Pocket sprung is generally the superior choice for most sleepers.
Is memory foam good for back pain?
Memory foam can be very effective for back pain as it contours to the body's natural curves and distributes pressure evenly. However, if you need firm spinal support, a medium-firm pocket sprung or hybrid mattress may work better. It depends on the type and cause of your back pain — our mattress quiz can help match you to the right choice for your specific needs.
Do I need a specific mattress for my bed frame?
The most important thing is getting the right size. Most mattresses work with most frames. The exception is slatted frames — if the slats are more than 7cm apart you may need a sturdier mattress or a slatted base insert. Divan beds with a platform top provide the firmest, most even support and suit any mattress type. Adjustable beds require a specially designed flexible mattress.
What does spring count actually mean?
Spring count refers to the number of individual pocket springs in a king size mattress. Higher count generally means more targeted support — but it's not the only factor in quality. A 1,000 spring mattress from a reputable brand will often outperform a cheaper 3,000 spring mattress. The gauge of the springs, the fillings above them, and overall build quality matter just as much as the count.
How do I know if my mattress is too soft or too firm?
A mattress that's too soft will cause you to sink and feel unsupported — you may wake with lower back aches or find it hard to change position. One that's too firm creates pressure points at the hips and shoulders, especially for side sleepers. Ideally your spine should be in a neutral position — not bowed downward or arched upward — when lying in your normal sleep position.
What size mattress do I need?
The right size depends on your bedroom dimensions, whether you sleep alone or with a partner, and how much space you personally need to sleep comfortably. A double (135 x 190cm) is the most popular choice for couples in smaller rooms. A king size (150 x 200cm) gives noticeably more width and length and is worth the upgrade if your room allows it. A super king (180 x 200cm) is ideal if space is no object. For a single sleeper, a small double (120 x 190cm) gives room to stretch without taking up too much floor space.
What's the best mattress for couples?
The ideal couples mattress minimises motion transfer so neither partner disturbs the other. Pocket sprung mattresses with a high spring count (1,500+) are excellent for this as each spring reacts independently. Memory foam and hybrid mattresses also absorb movement well. If you and your partner prefer very different firmness levels, a zip and link mattress lets you join two mattresses together — each person gets their preferred feel.
How do I care for and maintain my mattress?
Rotate your mattress 180 degrees every 3 months for the first year, then every 6 months after (unless it's a no-turn model). Use a good quality mattress protector to guard against moisture and staining. Vacuum the surface regularly to remove dust. Allow your mattress to air periodically — pull back the covers for 20 minutes each morning before making the bed.

What are the disadvantages of a super king size?

A super king-size, while offering exceptional space and comfort, also has several disadvantages to consider. Here are some potential drawbacks:

Disadvantages of a Super King-Size

1. Cost:

  • Higher Purchase Price: Super king-size are more expensive than standard king-size or smaller sizes. The cost includes not only the frame but also the mattress, bedding, and accessories.
  • Bedding Costs: Bedding for super king-size, including sheets, duvet covers, and mattress protectors, is often significantly more expensive and might require special or custom sizes.

2. Room Size Requirements:

  • Space Constraints: A super king-size requires a very large bedroom to fit comfortably. In smaller rooms, it can make the space feel overcrowded or cramped, affecting the overall functionality and appearance of the room.
  • Furniture Layout: The large size can limit your options for arranging other furniture and might restrict the flow of movement within the room.

3. Handling and Mobility:

  • Difficult to Move: Super king-sizes are heavy and bulky, making them challenging to move or reposition. This can be a significant issue if you relocate frequently or like to change your room layout often.
  • Assembly: The assembly process for a super king-size can be complex and time-consuming, requiring more effort and potentially additional help.

4. Maintenance:

  • Cleaning and Care: Larger sizes can be more difficult to clean and maintain. For instance, rotating or flipping a super king-size can be cumbersome, and finding appropriate cleaning services or products might be challenging.
  • Stain Management: Any spills or stains on a large size are harder to address, and professional cleaning might be required.

5. Heat Retention:

  • Temperature Regulation: A super king-size can retain more heat due to its size and the amount of bedding used, which might be uncomfortable in warmer climates or for individuals who prefer a cooler sleeping environment.

6. Visual Impact:

  • Room Aesthetics: In a small room, a super king-size can dominate the space and impact the overall aesthetics, making the room feel unbalanced or crowded.

7. Comfort Preferences:

  • Intimacy vs. Space: While a super king-size provides ample space, some individuals might find the large size detracts from the intimacy of sharing with a partner. The additional space might be less desirable for those who prefer to be closer during sleep.

8. Accessibility:

  • Difficulty Accessing: For those with mobility issues, getting in and out of a very large size can be more challenging, particularly if it is higher off the ground.

Conclusion

A super king-size offers significant space and luxury, but it comes with considerations such as cost, room size requirements, and practical challenges in handling and maintenance. Weighing these disadvantages against the benefits can help determine if a super king-size is the right choice for your needs and living space.
