King Size Cooling Soft/Med Memory Foam Pressure Relieving Mattresses

Balances comfort and support, providing a soft feel with enough support for proper spinal alignment. Ideal for sleepers with a lighter build who may find a medium mattress to be too firm and want a little extra give to maintain good sleep posture

Memory foam has the ability to conform to the shape of the body, allowing for even weight distribution and pressure relief. Memory Foam will return to its original shape once pressure is removed. The makeup of memory foam mattresses proves popular with people who suffer from joint pain, back pain.


Pressure-relieving mattresses are designed to distribute the body's weight more evenly across the surface of the mattress, reducing pressure on specific points such as the hips, shoulders, and spine. This can help to alleviate discomfort and pain and promote better circulation and more restful sleep.

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.

2. California King

  • Use: Popular on the West Coast, the California King is longer but slightly narrower than a Standard King, making it ideal for taller individuals.

3. UK King

  • Dimensions (UK): 60 inches wide by 78 inches long (150 cm x 200 cm)

Conclusion

The various king-size options provide flexibility and customization, allowing you to select the best option for your comfort and room layout.

What are the disadvantages of a king size?

While a king-size offers many benefits, such as increased space and comfort, there are also some potential disadvantages to consider:

Disadvantages of a King-Size

1. Cost:

  • Higher Initial Investment: King-size and their associated bedding, such as sheets, duvets, and mattress protectors, are typically more expensive than smaller sizes.
  • Maintenance Costs: The larger size may lead to higher costs for cleaning and replacing bedding and mattress accessories.

2. Room Size Requirements:

  • Space Constraints: A king-size requires a larger bedroom to accommodate its dimensions comfortably while leaving enough space for movement and other furniture. In smaller rooms, a king-size might make the space feel cramped.

3. Mobility and Handling:

  • Difficult to Move: King-size can be heavy and cumbersome, making them challenging to move or reposition, particularly if you are relocating or redecorating frequently.
  • Assembly: Assembly can be more complex and time-consuming compared to smaller sizes, requiring more effort to set up.

4. Cost of Accessories:

  • Bedding Costs: King-size bedding, including sheets, comforters, and mattress protectors, is often more expensive and may require special sizes or custom options.
  • Storage: Larger bedding and accessories may require more storage space when not in use.

5. Room Layout:

  • Limited Flexibility: In smaller rooms, a king-size can limit your options for arranging other furniture and might restrict the flow of movement within the room.
  • Visual Balance: In a small room, a king-size might dominate the space, affecting the overall aesthetics and balance of the room.

6. Heat Retention:

  • Warmth: Larger sizes may retain more heat, which can be a disadvantage in warmer climates or for individuals who prefer a cooler sleeping environment. However, this can also be mitigated with appropriate bedding.

7. Comfort and Use:

  • Space vs. Intimacy: While the extra space can be comfortable, some people may prefer a smaller size for a cozier or more intimate feel, especially if they like to be close to their partner during sleep.

8. Maintenance:

  • Mattress Maintenance: A larger size can be harder to clean and maintain, especially if it becomes stained or needs to be rotated or flipped regularly.

Conclusion

A king-size provides substantial benefits in terms of space and comfort, but these advantages come with some trade-offs, including higher costs, space requirements, and practical considerations for handling and maintenance. Assessing these potential disadvantages in relation to your specific needs and room size can help determine whether a king-size is the right choice for you.
