We’ve all experienced it: tossing and turning through the night, struggling to find that perfect sleep position, and waking up with more aches than we went to bed with. A good mattress isn’t just a luxury—it’s essential for our overall well-being. But what truly makes a mattress comfortable? Is it the materials, the firmness, the size—or is there something hidden inside that does all the hard work?
One of the most important and often overlooked elements is the mattress spring system—specifically, pocket springs. These small, individually wrapped coils have revolutionized how mattresses are built and how we sleep. Whether you’re a side sleeper, a back sleeper, or someone sharing the bed with a restless partner, pocket springs offer tailored support that responds to your body, not just the surface.
In this blog, we’ll take you beneath the surface to explain how pocket springs work, why they matter, and how they create the foundation for a truly restful night’s sleep.
What Is a Pocket Spring Mattress?
Pocket sprung mattresses are a type of mattress that uses individually wrapped springs, each encased in its own fabric pocket, to provide targeted support and enhanced comfort. Unlike traditional spring systems, where coils are interconnected and move as a single unit, pocket springs move independently. This means the mattress responds to your unique shape, weight, and sleeping position—minimizing motion transfer and reducing pressure points.
In contrast, open-coil or Bonnell spring mattresses use a wire frame to connect all the springs together. While more affordable, these mattresses often wear out faster and don’t offer the same level of tailored support. You may feel more motion transfer with an open-coil system, which can be disruptive if you share your bed.
Pocket spring mattresses vary in spring count, typically ranging from 800 to over 2,000 springs. Higher spring counts generally provide more responsive support, especially for heavier individuals or couples, though material quality and mattress construction are just as important as the numbers.
With a pocket sprung mattress, you get a sleep surface that’s both supportive and adaptive—a modern solution for those seeking comfort, durability, and a more personalised sleep experience.
How Pocket Springs Work: The Engineering Behind the Comfort
At the heart of a pocket sprung mattress lies a cleverly engineered system designed to work with your body, not against it. Each spring is individually wrapped in its own fabric pocket—hence the name—allowing it to move independently from the others. This independence is what sets pocket springs apart from traditional interconnected spring systems.
So, how do pocket springs work exactly? When you lie down, each spring reacts to the pressure placed directly on it. This means that the mattress contours to your body's natural curves, offering zoned support—more give under your shoulders and hips, and more resistance where your spine needs to stay aligned. The result? Reduced pressure points, improved posture, and a more comfortable night’s sleep.
Because the springs aren't linked together, movement on one side of the bed has little impact on the other. This is especially beneficial for couples—if one partner moves or gets out of bed, the other is less likely to be disturbed. It’s what’s known in the industry as motion isolation, and pocket springs excel at it.
Additionally, the pockets themselves are often made from breathable fabrics, which help regulate airflow and maintain a cooler sleeping environment. Combined with high-quality upholstery layers—such as natural wool, latex, or cotton—the spring system creates a balance of responsiveness and plushness that feels supportive without being too firm or too soft.
In short, a pocket spring mattress doesn’t just support you—it adapts to you. And that’s what makes it one of the most advanced and comfortable options in the world of sleep systems today.
The Science of Support: Why Pocket Springs Matter
Behind every great night's sleep is proper support—and that’s where pocket springs truly shine. Unlike foam or interconnected spring systems, pocket spring mattresses deliver precise, responsive support that adapts to your body in real time. This isn’t just about comfort—it’s about protecting your posture and preventing long-term aches and pains.
When you sleep, your spine should remain in a neutral, aligned position. Pocket springs help maintain this alignment by responding individually to areas of pressure—like your shoulders and hips—while keeping the rest of your body evenly supported. This dynamic adjustment means no single part of your body bears too much weight for too long, which is crucial for reducing pressure build-up and improving circulation.
For those with back pain, this targeted support can make a noticeable difference. While foam mattresses can sometimes feel too soft or sink too deeply, pocket spring systems strike a balance: firm where you need it, gentle where you don’t.
The independence of the springs also reduces partner disturbance—a must-have feature for light sleepers. In essence, the pocket spring mattress acts like a custom-built sleep system, quietly adapting to your movements and providing a level of support that’s both scientific and intuitive.
Pocket Spring Counts and Mattress Tension: What’s Right for You?
When shopping for a pocket sprung mattress, one of the most common questions is: How many springs do I need? The answer isn’t one-size-fits-all—but understanding the relationship between spring count and mattress tension can help you find the perfect match.
Spring count refers to the number of individual pocket springs within a standard king size mattress (usually the reference size used across brands). A typical range is 800 to 2000 springs, although some premium models go even higher. While it might seem like “more is better,” that’s not always true. A higher spring count allows for finer body contouring and more responsive support, but the quality of the springs, the materials used, and your body type are just as important.
Here’s a quick guide:
- 800–1000 springs: Suitable for lighter individuals or guest bedrooms where daily use is limited.
- 1000–1500 springs: Ideal for most adults and couples—offering balanced support and motion control.
- 1500–2000+ springs: Great for heavier sleepers or those who prefer a more tailored, luxurious feel.
Spring count also affects tension levels, which determine how soft or firm the mattress feels:
- Soft: Better for side sleepers or lighter individuals.
- Medium: The most versatile, suitable for most sleep positions.
- Firm: Best for back or stomach sleepers, or anyone needing enhanced spinal support.
Ultimately, the right combination depends on your personal sleep preferences—but understanding the interplay between spring count and tension will help you make a more informed choice.

Common Myths About Pocket Sprung Mattresses
With so many mattress types on the market, it’s easy for misconceptions to take root—especially when it comes to pocket sprung mattresses. Let’s debunk a few of the most common myths:
Myth 1: The higher the spring count, the better the mattress.
Spring count plays a role, but the quality of materials, tension, and construction are just as important for a supportive sleep experience.
Myth 2: Spring mattresses are noisy and outdated.
Pocket springs move independently and are encased in fabric, meaning they’re quiet, modern, and engineered for performance.
Myth 3: Foam is always more supportive than springs.
Not necessarily—pocket springs offer zoned, responsive support that rivals or even outperforms some foam options, especially for breathability and longevity.
