In this article, we will dive deeper into what exactly a spring coil mattress is, how it works, and the benefits it offers. So, if you're in the market for a new mattress or simply curious about the different types available, keep reading to learn more!

Understanding the Spring Coil Mattress

A spring coil mattress, also known as an innerspring mattress, is composed of a network of metal coils or springs that provide support and structure to the mattress. These coils are generally made of steel and come in various thicknesses and shapes, such as Bonnell coils, offset coils, and pocketed coils. The design and arrangement of these coils can vary depending on the mattress manufacturer and the specific model.

The primary purpose of the coil system in a spring mattress is to help distribute the body weight evenly across the surface of the mattress. By doing so, it reduces pressure points and maintains proper spinal alignment while sleeping. The higher the coil count, the better the support and motion isolation of the mattress.

The Inner Workings of a Spring Coil Mattress

A spring coil mattress consists of several layers that work together to provide optimal comfort and support. Let's take a closer look at each of these layers:

1. The Comfort Layer: The top layer of a spring coil mattress is responsible for providing comfort and cushioning. It typically consists of materials like memory foam, latex, or pillow tops. This layer ensures a soft and cozy sleeping surface, relieving pressure points and enhancing overall comfort.

2. The Support Layer: The support layer of a spring coil mattress is where the metal coils or springs come into play. These coils act as a supportive base for the mattress, providing the necessary bounce and pushback. The thickness and arrangement of the springs can vary, impacting the mattress's level of support and firmness.

3. The Insulation Layer: Located between the comfort and support layers, the insulation layer prevents the comfort layer from sagging into the springs. It helps the mattress maintain its shape and provides additional support.

4. The Edge Support System: Some spring coil mattresses come with reinforced edges to prevent sagging and enhance the overall stability of the mattress. This feature is particularly beneficial for those who tend to sleep near the edge or share the bed with a partner.

5. The Foundation Layer: The foundation layer, also known as the box spring, provides additional support to the entire mattress. It acts as a base and helps distribute weight evenly. However, not all spring coil mattresses require a separate foundation layer, as some models come with built-in foundations or can be used with adjustable bed frames.

The Benefits of a Spring Coil Mattress

Now that we've explored the inner workings of a spring coil mattress, let's discuss the benefits it offers:

1. Support: One of the significant advantages of a spring coil mattress is its ability to provide excellent support. The coil system enables the mattress to conform to the body's natural curves, providing support where it is needed most, such as the lower back and shoulders.

2. Durability: Spring coil mattresses are known for their durability. The coil system, typically made of sturdy steel, ensures the mattress remains supportive and maintains its shape for a long time. With proper care, a well-made spring coil mattress can last between 7 to 10 years.

3. Better Air Circulation: The design of a spring coil mattress allows for better air circulation, promoting breathability and preventing heat buildup. This feature is particularly beneficial for those who tend to sleep hot or live in warmer climates.

4. Affordability: Compared to other types of mattresses, spring coil mattresses tend to be more budget-friendly. With a wide range of options available, there is a spring coil mattress to fit almost any budget. This makes it an attractive choice for those who want a high-quality mattress without breaking the bank.

5. Familiarity: Spring coil mattresses have been around for a long time, and many people are familiar with their feel and support. This familiarity can make the transition to a new mattress more comfortable, especially for those who have been sleeping on a traditional spring mattress for years.


In conclusion, a spring coil mattress is a popular choice that offers excellent support, durability, and affordability. Its unique design consisting of a network of metal coils or springs ensures an even distribution of body weight, reducing pressure points and allowing for proper spinal alignment. With various layers working together, including a comfort layer, support layer, insulation layer, edge support system, and foundation layer, a spring coil mattress provides a balanced combination of comfort and support for a restful night's sleep. So, if you're in the market for a new mattress, considering a spring coil mattress might just be the right choice for you.
