Med/Firm Memory Gel Good Airflow & Breathability Mattresses

A medium-firm mattress is a level of firmness that is slightly firmer than a medium mattress but still has a moderate amount of "give". A medium firm mattress is extremely comfortable. It's perfect if you want a little extra support but still, like your bed to feel cosy and soft.

Memory gel is a combination of gel and memory foam, which creates a material that is both supportive and comfortable. Additionally, many memory gel products are designed to be breathable and moisture-wicking, which can help to regulate temperature and prevent overheating during sleep.


The open coil structure allows air to circulate, helping to prevent overheating.

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'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.

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.

Memory Gel FAQ's

What is memory gel?

A memory gel mattress is a hybrid mattress that integrates memory foam with gel-infused technology to enhance temperature regulation and overall comfort.

How It Works

  • Memory Foam Base: Molds to the body’s shape, alleviating pressure points and offering targeted support.

  • Gel Infusion or Gel Layers: Works to disperse heat and prevent overheating, addressing a common concern with traditional memory foam.

Key Benefits
Cooler Sleep: The gel actively draws heat away from the body, promoting a more comfortable sleeping temperature.
Pressure Relief: The memory foam conforms to your body, reducing strain on joints and improving comfort.
Motion Isolation: Effectively absorbs movement, making it an excellent choice for couples.

How does a memory gel mattress differ from traditional memory foam?

A memory gel mattress stands apart from traditional memory foam in several important ways:

  1. Temperature Regulation

    • Memory Gel: Features cooling gel beads or a gel layer to disperse heat, keeping sleepers cooler throughout the night.

    • Traditional Memory Foam: Often retains heat, which can make it feel warmer, particularly for those who sleep hot.

  2. Firmness & Feel

    • Memory Gel: Typically has a slightly firmer feel due to the gel infusion, while still conforming to the body’s shape.

    • Traditional Memory Foam: Generally softer and more moldable, sometimes creating a "sinking" sensation.

  3. Responsiveness & Bounce

    • Memory Gel: More responsive, meaning it bounces back quicker when you move or change positions.

    • Traditional Memory Foam: Slower to regain its shape, which can feel less dynamic when shifting during sleep.

  4. Durability & Sagging

    • Memory Gel: Tends to maintain its shape longer and resists sagging more effectively than traditional memory foam.

    • Traditional Memory Foam: May develop body impressions or indentations over time.

Which One is Best for You?
✔️ Hot Sleepers - Opt for a Memory Gel mattress for a cooler sleep experience.
✔️ Pressure Relief - Both are excellent, but traditional memory foam provides deeper contouring.
✔️ Firmer Feel - Memory Gel is the better option.
✔️ Budget-Friendly - Traditional Memory Foam is usually more affordable.

Does the gel layer really help with heat regulation?

The gel layer in a memory gel mattress does contribute to heat regulation, but its effectiveness largely depends on the type and quality of the gel infusion.

How the Gel Layer Works
 Gel Beads or Gel-Infused Foam: Absorbs and disperses body heat, preventing it from accumulating.
 Phase Change Materials (PCM): High-end models may use advanced cooling gel that actively regulates temperature.
 Open-Cell Foam Structure: Many memory gel mattresses feature a more breathable foam design, promoting better airflow.

How Effective Is It?
Better than Traditional Memory Foam: While regular memory foam tends to trap heat, gel-infused foam helps reduce overheating.
Not as Cool as Innerspring or Hybrid Mattresses: Hybrid beds with coils or latex typically offer superior airflow and cooling.
Varies by Quality: Lower-quality gel-infused foam may still sleep warm if it lacks proper ventilation or advanced cooling features.

Tip: If you’re a hot sleeper, consider a memory gel mattress with additional cooling technologies, such as:
✔️ Breathable covers (e.g., Tencel, bamboo)
✔️ Copper or graphite-infused foam
✔️ Hybrid designs with pocket springs for enhanced airflow.

Are gel mattresses good for all sleep positions?

Memory gel mattresses can suit all sleep positions, but the ideal choice depends on the firmness level and the sleeper’s body weight.

Best Firmness for Each Sleep Position
Side Sleepers → Soft to Medium (4-6/10 firmness)

  • Gel memory foam conforms to the shoulders and hips, easing pressure points.

  • Opt for a plush comfort layer to avoid discomfort.

Back Sleepers → Medium to Medium-Firm (6-8/10 firmness)

  • Requires spinal support with some contouring.

  • Gel foam aids in lumbar support and helps prevent lower back pain.

 Stomach Sleepers → Firm (7-9/10 firmness)

  • A soft mattress can cause the hips to sink too much, leading to spinal misalignment.

  • A firmer gel mattress prevents excessive sinking and supports the midsection.

 Combination Sleepers → Medium-Firm (5-7/10 firmness)

  • Responsive gel foam is ideal for easy movement between positions.

  • Look for zoned support to adapt to various sleeping postures.

Additional Factors to Consider
Body Weight: Heavier sleepers (over 230 lbs) may benefit from a firmer hybrid gel mattress for enhanced support.
Motion Isolation: Gel memory foam excels at reducing motion transfer, making it a great choice for couples.
Cooling Needs: If you sleep hot, consider a gel-infused hybrid mattress for improved airflow and temperature regulation.
