How are pocket spring mattresses made?

When it comes to quality sleep, pocket spring mattresses — also known as independent spring  mattresses — are a popular choice for those seeking greater support than other types of mattress can offer.

They are a popular choice for those with specific requirements or who want a reliable, long-lasting product.

But how are pocket spring mattresses made? Who are they really recommended for? In this guide, we explain what makes them special to help you decide if one is right for you.

What is a pocket spring mattress and how is it made?

A pocket spring mattress consists of hundreds or thousands of steel springs, each one enclosed in a breathable fabric pocket. This structure enables each spring to react independently to the weight of the body.

The result is personalised, progressive support: the mattress adapts to the different areas of your body — shoulders, back and pelvis — without creating pressure points. It is precisely this independence of the springs that makes sleep more stable and comfortable, particularly in double mattresses.

The spring structure is often combined with layers of advanced materials, such as memory foam, to create a pocket spring mattress with memory foam — an ideal combination of technology and tradition.

Recommended height and number of springs

Height is an important factor to consider. Generally, a good pocket spring mattress is between 22 and 30 cm high.

Adequate thickness allows for better weight distribution and orthopaedic support that adapts to the shape of your body. The most advanced models, especially ergonomic ones or those with memory foam layers, are often greater in height to ensure superior performance.

Another fundamental aspect is the number of springs. There is no single answer to the question of how many springs a mattress of this type should have.

As a rough guide, mattresses with between 800 and 1,000 springs offer a good level of comfort, while those with 1,200 to 1,600 springs or more provide more precise support and greater adaptability to your body shape.

A high number of springs allows for a more precise response to body movements and improves rest independence: if one person moves, the other can continue to sleep peacefully without being disturbed.

Durability of pocket spring mattresses

A high-quality pocket spring mattress can last an average of 10–12 years, providing consistent support and comfort throughout its lifespan.

Several factors influence the lifespan: the quality of the steel in the springs, the density of the covering materials, the presence of additional layers, and of course, the mattress’s daily use.

Maintenance also plays an important role: rotating the mattress periodically and pairing it with a suitable bed base helps preserve its performance over time.

Mollyflex mattresses are designed to be reliable and long-lasting, thanks to their certified materials and careful workmanship. They are built to provide your family with restful sleep year after year.

Who is the pocket spring mattress recommended for?

The pocket spring mattress is ideal for those seeking a balance of support and comfort without compromising on stability. It is particularly suitable for couples because the independent springs reduce the transmission of night-time movements, improving the quality of rest for both partners.

It is also recommended for those who want more supportive care for their back and joints over time. The spring structure also guarantees breathability and hygiene — qualities that are highly valued by families and anyone looking for a reliable, long-lasting mattress.
