What is a Pocket Sprung Mattress?

When it comes to choosing the perfect mattress, comfort and support are key, and pocket sprung mattresses are designed to deliver both. Known for their high-quality construction and tailored support, these mattresses feature individual springs housed in their own fabric pockets. This design allows each spring to move independently, adapting to your body’s unique shape and reducing motion transfer. Unlike traditional open coil mattresses, where springs are interconnected, these independent springs work on their own to respond to your body.

In this blog, we’ll break down what makes pocket sprung mattresses stand out, how they differ from other types, and why they might be the right choice for your best night’s sleep.

Pocket Spring Counts and Tensions

When exploring pocket sprung mattresses, two important terms you’ll come across are spring count and tension. These factors determine how supportive, comfortable, and suitable the mattress is for your body and sleep style.

What Is Spring Count?

The spring count refers to the number of individual pocket springs inside a king-size mattress (5ft). A higher number of springs often means better support and comfort, but more isn’t always better — it’s about quality and suitability.

1,000 Springs

A dependable everyday choice that provides balanced support without stretching your budget. Ideal for guest rooms, solo sleepers, or lighter individuals looking for reliable comfort.

2,000 Springs

Offers noticeably improved support and responsiveness, especially for two people sharing a bed. Perfect for couples seeking more personalised comfort and minimal motion transfer.

3,000–5,000+ Springs

Luxury-level comfort. These mattresses often feature layers of mini or micro springs, providing advanced contouring and precision support. Best suited for couples, heavier individuals, or anyone seeking a truly premium sleep experience.

Different Types of Pocket Sprung Mattresses

Not all pocket-sprung mattresses are created equal. There are several variations, each designed to meet specific sleep preferences and requirements. At Sussex Beds, we stock a wide range, including the following types:

Standard Pocket Sprung

The classic version. These contain one layer of full-sized springs encased in fabric pockets, offering balanced support and motion isolation.

Ideal for: Everyday comfort and support for most sleep styles.

Examples of Standard Pocket Sprung Mattresses

• Classic Cashmere Mattress 
• Citrine Mattress

Mini Pocket Sprung

Mini pocket springs are smaller and finer, often used in multiple layers to offer extra responsiveness and comfort.

Ideal for: People seeking a luxurious feel with extra contouring.

Example of Mattresses with Mini Pocket Springs

• Wightwick Mattress
• Flora Care Mattress

Natural Filled Pocket Sprung

Filled with natural materials like wool, silk, or cotton, these mattresses offer breathability, temperature regulation, and eco-friendliness.

Ideal for: Hot sleepers or those looking for a sustainable option.

Example of Mattresses with Natural Fillings & Pocket Springs

• Gosfield Mattress
• Rufford Ortho Mattress

Hybrid Pocket Sprung

Combining pocket springs with memory foam, latex, or gel layers, hybrid mattresses blend the best of both worlds: support and cushioning.

Ideal for: People who want spring support with the comfort of modern foams.

Pocket Sprung Mattresses vs. Other Mattress Types

While pocket sprung mattresses offer tailored support and durability, how do they compare to other popular mattress types?

Memory Foam

Memory foam contours to your body and absorbs motion well. However, it can retain heat and lacks the bounce and breathability of pocket springs.

Best for: Pressure relief, not ideal for those who sleep hot.

Gel Foam

Similar to memory foam but infused with gel for better temperature control. Still lacks the natural bounce and edge support of springs.

Best for: Cooling comfort with soft support.

Open Coil (Bonnell)

An older style of spring system where all springs are connected. Less responsive and can cause motion transfer.

Best for: Budget buys or guest rooms.

Latex

Naturally breathable and durable, latex offers a bouncy, firm feel. Often combined with pocket springs in hybrid designs.

Best for: Eco-conscious buyers wanting a responsive surface.

The Benefits of a Pocket Sprung Mattress

Here’s why pocket sprung mattresses continue to be one of the most recommended choices:

• Tailored Support: Each spring responds individually, contouring to your body shape for full-body support.
• Motion Isolation: Minimises disruption from a partner moving at night.
• Breathability: Air can flow more freely, especially when paired with natural fillings.
• Durability: Pocket sprung mattresses are often more robust than foam-only models.
• Pressure Relief: Great for relieving discomfort in joints, hips, shoulders, and the back.
• Variety: With so many types, tensions, and fillings available, there’s something for every sleeper.

Pocket sprung mattresses combine traditional craftsmanship with modern comfort to create an excellent sleep experience. Whether you’re seeking all-over support, pressure relief, or something that just feels indulgent, there’s a pocket-sprung option that fits your lifestyle.
