All About Bed Coils: Your Guide to Spring Mattresses

When it comes to choosing the right mattress, the options can feel overwhelming. From memory foam to hybrid models, there’s a massive array of beds on the market. But one of the most trusted and time-tested designs is the spring mattress (also known as a coil mattress). At The Mattress Warehouse, we believe that when you have the right information, buying a mattress doesn’t have to be complicated. This guide will walk you through everything you need to know about bed coils, their benefits, and some of the best spring mattresses available in South Africa.

Why spring mattresses will always remain popular

Spring mattresses have been around for decades, and their design continues to evolve with new technology. Unlike foam-only beds, spring mattresses use a coil system to provide structure, support, and durability. The springs are usually layered with foam, latex, or fabric to enhance comfort.

Many sleepers prefer spring beds because they:

Provide strong support for the spine and joints.
Offer excellent airflow, keeping you cool at night.
They are available at a wide range of price points.
Last for many years with proper care.

At The Mattress Warehouse, you’ll find a wide variety of spring mattresses, from budget-friendly options to luxury coil beds with advanced features.

The different types of bed coils – what you need to know

Not all coils are made the same. Modern spring mattresses feature different coil systems, each designed to provide unique benefits. Here are the three most common types:

1. Continuous coils

Made from one long continuous wire, these S-shaped coils are known for their durability and stability. They provide firm support and are often used in long-lasting, affordable mattresses. Brands like Serta offer excellent options that make use of this technology.

2. Pocketed coils

Pocketed coils (also known as individually wrapped coils) are designed to reduce motion transfer. Each spring is wrapped in fabric, allowing it to move independently. This means if your partner turns over at night, you’re less likely to feel it. These mattresses are especially popular for couples and can be found in premium collections like the Cloud Nine i-Sleep range.

3. Hourglass coils

The most traditional coil design, hourglass or Bonnell coils, are shaped like an hourglass. They’re reliable, cost-effective, and widely used in entry-level and mid-range mattresses. While they may not have the same motion isolation as pocketed coils, they remain a trusted and affordable option.

Understanding coil gauge and comfort levels

When shopping for a spring mattress, you may hear the term coil gauge. This refers to the thickness of the coil wire:

A lower gauge number means a thicker coil, offering firmer support.
A higher gauge number means a thinner coil, which can feel softer.

That said, coil count and gauge are becoming less important than the overall design. Today’s coil mattresses are engineered for balanced support and comfort, regardless of coil thickness.

Spring mattresses vs. foam mattresses: what’s best for you?

One of the most common debates is whether to choose a coil or foam mattress. Each has its benefits:

Spring mattresses: Affordable, durable, and breathable. They also allow for flipping and rotation, extending their lifespan.
Foam mattresses are excellent at pressure relief and contouring to the body, but they tend to retain heat and cannot usually be flipped.

If you love a mattress that feels bouncy, supportive, and cool, spring mattresses may be the perfect fit. If you prefer deep contouring and pressure relief, foam may be the better choice. For the best of both worlds, consider a hybrid mattress that combines coils and foam.
