Memory Foam vs Pocket Sprung Mattresses

In a market brimming with endless mattress choices, memory foam and pocket sprung mattresses remain two of the most popular options. But for most people, especially those not well-versed in mattress jargon, it can be genuinely confusing to figure out which one is better suited to their needs. If you’re feeling stuck between the two, don’t worry - we’ve laid it all out clearly to help you choose with confidence. In this guide, you’ll find a side-by-side comparison, a breakdown of their key differences, when each one works best, and practical advice on how to pick the right mattress for your sleep style and comfort.

Side-by-Side Comparison Table

Before we dive into the details of each mattress type, here’s a quick comparison to give you a snapshot of how memory foam and pocket sprung mattresses differ across key features. This table is especially useful if you’re still weighing what matters most—be it firmness, temperature control, or edge support. While individual models may vary, these general pointers should help you get a clearer sense of what to expect from each type.

Core Differences

Memory foam and pocket sprung mattresses are built using very different materials, and that plays a big role in how they feel and perform. From the way they support your body to how they manage heat and motion, each mattress type brings a distinct sleep experience. Here’s a closer look at their core construction and how that affects comfort, support, and overall durability.

Memory Foam: Features & Best Use

Memory foam mattresses are known for their deep, contouring comfort and pressure-relieving properties, making them a popular choice for sleepers who like a ‘hugged’ feeling. They’re particularly valued for motion absorption and quiet support - especially helpful if you share your bed.

Construction & Layers

Memory foam mattresses are typically made up of three to five layers, each with a distinct function. The top layer is usually made of viscoelastic memory foam that responds to body heat and pressure, offering a cradling feel. Beneath that, one or more transition layers provide cushioning and distribute weight evenly. The base layer is constructed from high-density foam, giving the mattress its overall structure and durability. Some models in the UK also include gel-infused or open-cell layers to address overheating concerns - particularly useful for warmer sleepers.

Types of Memory Foam

There are different types of memory foam used in UK mattresses, each offering a slightly different feel and level of support:

• Traditional Memory Foam: This is the standard viscoelastic foam known for deep contouring but can retain more heat than other types.
• Gel-Infused Memory Foam: This version has gel beads or liquid gel added to help draw heat away from the body for a cooler sleep surface.
• Open-Cell Memory Foam: Designed with a more breathable structure, this type allows better airflow to reduce heat build-up.
• Plant-Based Memory Foam: Made partly from natural ingredients, this eco-friendlier version has a faster response time and typically sleeps cooler.

Who It’s Best For

Memory foam is best suited for side sleepers and those who struggle with joint or back pain, as it moulds to the body's curves and helps reduce pressure points. It's also ideal for couples, light sleepers, or those sensitive to movement, since the foam absorbs motion exceptionally well. People in flats or quieter spaces may also appreciate its silent performance, as it doesn’t squeak or creak like spring mattresses might.

Pros

• Superior Pressure Relief: The foam adapts to your body shape and weight, easing pressure on the shoulders, hips, and joints.
• Excellent Motion Isolation: Ideal for couples, it absorbs movement so one person’s tossing and turning doesn’t disturb the other.
• Silent Sleep Surface: No creaks or spring noises - memory foam offers a completely quiet night’s sleep.
• Affordable: Many popular mattress brands in the UK offer good quality memory foam mattresses starting from around £100-150, making them accessible for most budgets.

Cons

• Tends to Retain Heat: Unless it’s gel-infused or ventilated, memory foam can sleep warm - especially in UK homes with central heating.
• Limited Bounce: The slow-response feel can make movement feel restricted, which some may find uncomfortable when changing positions.
• Weaker Edge Support: Sitting or sleeping near the edge may feel unstable unless reinforced by a hybrid design.
• Initial Off-Gassing Smell: New memory foam mattresses may emit a temporary chemical odour when first unboxed - though this usually fades within a few days.

Pocket Sprung: Features & Best Use

Pocket sprung mattresses are known for their supportive, responsive feel, offering a more traditional sleep surface compared to foam. Thanks to their individual coil construction, they provide tailored support and good airflow - ideal for those who prefer a firmer and cooler mattress.

Construction & Layers

A pocket sprung mattress is made up of thousands of individual springs, each housed in its own fabric pocket. This design allows each spring to move independently, adjusting to your body weight and shape without disturbing the rest of the mattress. Above the spring unit, you’ll usually find comfort layers made from foam, wool, or other natural fibres, which can alter the feel from soft to firm. Some premium mattresses also include dual or zoned spring systems for extra lumbar support or edge stability. The overall result is a mattress that combines bounce with personalised support, making it a long-standing favourite in British homes.

Types of Pocket Springs

There are several variations of pocket sprung mattresses in the UK market, catering to different sleep needs and budgets:

• Standard Pocket Spring: Features a single layer of springs that move independently to provide balanced support and reduce motion transfer.
• Zoned Pocket Spring: Offers firmer springs in areas like the hips and lower back, giving more targeted support where your body needs it most.
• Mini or Micro Springs: These smaller springs are used in additional layers to enhance comfort and responsiveness, often found in luxury mattresses.
• Natural Fillings: Many UK brands use natural layers like wool, cashmere or cotton atop the springs, offering breathability and a more traditional feel.

Who It’s Best For

Pocket sprung mattresses are a solid choice for back and stomach sleepers, as well as those who prefer a slightly firmer, more responsive surface. They're also a good option for hot sleepers or those living in warmer parts of the UK, thanks to their natural airflow. Heavier individuals often benefit from the robust support and structure that a high spring count model can offer.

Pros

• Responsive Support: The independent springs adjust to your movements quickly, helping to keep your spine aligned throughout the night.
• Better Airflow: Unlike foam, the open coil structure allows for natural ventilation - ideal for keeping cool under heavy duvets or in warmer months.
• Wide Range of Firmness Options: From plush to extra firm, you will find extensive options to match different sleep preferences.
• Edge-to-Edge Support: Many models include reinforced edges, making the full surface of the bed usable and more stable for sitting or sleeping near the sides.

Cons

• More Motion Transfer Than Foam: Although better than open coil beds, pocket sprung mattresses may still transfer some movement across the surface.
• Heavier to Move: Due to the metal spring core, these mattresses can be bulkier and more difficult to rotate or flip, especially in king or super king sizes.
• Potential for Squeaking Over Time: Lower-quality models may develop squeaks as the springs age, particularly if not well maintained.
• Price Can Vary Widely: While entry-level models are affordable, premium versions with natural fillings and high spring counts can be considerably more expensive.

How to Choose

Choosing between a memory foam and pocket sprung mattress isn’t just about personal preference - it’s about matching your mattress to your sleep style, body type, and everyday needs. Whether you live in a city flat, share your bed with a partner, or need better support for aches and pains, here’s what to keep in mind before buying:

Things to Consider

• Sleeping Position: Side sleepers often benefit from memory foam’s contouring comfort, while back and stomach sleepers may prefer the firm, responsive feel of a pocket sprung mattress.
• Body Weight: Heavier individuals (over 90 kg) may find better long-term support and durability in a high spring count pocket sprung mattress.
• Room Temperature: Memory foam can trap heat, so it may not be ideal if you tend to feel warm at night or live in a well-heated home. In that case, opt for a pocket sprung model or a foam mattress with cooling features.
• Partner Disturbance: If you share your bed and one of you tosses and turns, memory foam is usually the better choice for motion isolation.
• Budget and Longevity: Pocket sprung mattresses can range from affordable to luxury, but quality depends on spring count and materials. Memory foam mattresses often offer good value in the mid-range, but make sure they have high-density foam for better durability.
• Mattress Trial and Returns: Look for options that offer at least a 60-night sleep trial and free returns - especially if buying online.
• Delivery Access: Memory foam mattresses are often vacuum-packed and easier to carry upstairs or through tight hallways, which is ideal for flats or terraces with narrow entries.

Things to Avoid

• Going by Firmness Labels Alone: Terms like "medium-firm" vary between brands. Always check the mattress firmness rating, construction and materials rather than relying solely on the label.
• Skipping the Fine Print: Be cautious of budget mattresses with very low-density foam or minimal spring counts - they may not last more than a couple of years.
• Ignoring Trial Periods: Many buyers overlook the importance of a trial period. Without one, you’re stuck if the mattress doesn't suit you after a few weeks.

Now that you’re well equipped with a clear understanding of memory foam and pocket sprung mattresses, making the right choice should feel a lot less overwhelming. Whether you're after the pressure-relieving comfort of foam or the breathable support of springs, the key is to match your mattress to your lifestyle, sleep habits, and long-term needs. Take your time, compare your options, and remember - a well-chosen mattress isn’t just a purchase, it’s an investment in better sleep.
