What is the difference between coil and spring mattress?



When it comes to choosing a mattress, there are several options to consider, including coil and spring mattresses. These two types of mattresses are the most common and widely used options in the market. However, many people often wonder what the actual difference is between coil and spring mattresses. In this article, we will explore the distinctions between these two mattress types, helping you make an informed decision when purchasing your next mattress.

Coil Mattresses

Coil mattresses, also known as innerspring mattresses, have been popular for many years and are widely used across the globe. The core feature of a coil mattress is its internal system of metal coils or springs that provide support and bounce. These coils are usually made of tempered steel and are interconnected, forming a network within the mattress structure.

Coil mattresses offer different levels of support and firmness, depending on the number and thickness of the coils used. A higher coil count typically indicates better support and a greater ability to distribute weight evenly. These mattresses also come in various coil designs, including Bonnell coils, offset coils, continuous coils, and pocketed coils.

One of the key advantages of coil mattresses is their affordability. They are generally more budget-friendly compared to other types of mattresses in the market. Moreover, coil mattresses tend to have a longer lifespan compared to foam or latex mattresses. However, it is important to note that the overall durability and quality of a coil mattress depend on factors such as coil gauge, coil count, and the quality of materials used in its construction.

Spring Mattresses

While coil mattresses may be considered a type of spring mattress, the term "spring mattress" often refers to mattresses that utilize other types of springs, such as pocket springs or micro-springs. These springs are individually encased in fabric pockets, allowing them to work independently and provide targeted support to different areas of the body.

Spring mattresses are known for their exceptional comfort and motion isolation. Due to the independent nature of pocket springs, these mattresses effectively absorb movement, making them an ideal choice for couples or individuals who are easily disturbed by their partner's movements during the night. Moreover, spring mattresses offer excellent breathability and temperature regulation, as the space between the springs allows for increased air circulation.

The choice between a coil and spring mattress often depends on personal preferences and specific needs. Spring mattresses may be more suitable for individuals who prioritize motion isolation, targeted support, and temperature regulation. On the other hand, coil mattresses are an excellent option for those who seek a more traditional and affordable mattress with reliable support and bounce.

The Differences in Comfort and Support

When it comes to comfort and support, both coil and spring mattresses have their own unique characteristics. Coil mattresses, with their interconnected coils, provide a traditional bouncy feel that many people are accustomed to. The coils distribute weight evenly, contouring to the body's shape and providing support where it is needed. However, they may not offer as much targeted support as spring mattresses that utilize individual pocket springs. The pocket springs in a spring mattress work independently and offer more precise support to different areas of the body, relieving pressure points and ensuring a comfortable sleep experience.

In terms of firmness options, both coil and spring mattresses come in various firmness levels to cater to different preferences. Coil mattresses often provide a broad range of options, from soft to medium to firm, allowing consumers to choose the level of firmness that suits their needs best. Spring mattresses, particularly those with pocket springs, also offer different firmness options, ensuring that there is something for everyone.

Durability and Longevity

Durability and longevity are crucial factors to consider when purchasing a mattress, as they directly impact the value for money. Coil mattresses, especially those with a high coil count and quality construction, are generally known for their durability. The interconnected coils provide robust support, and the use of tempered steel enhances the overall lifespan of the mattress. However, coil mattresses may experience sagging or uneven wear over time, as the interconnected coils may not distribute weight as effectively as individual pocket springs.

Spring mattresses, especially those with pocket springs, are often associated with exceptional durability. The independent nature of pocket springs allows them to contour to the body's shape while maintaining their individual strength and resilience. This feature contributes to a longer lifespan and prevents sagging or uneven wear. Additionally, spring mattresses are less prone to developing permanent body impressions, ensuring consistent support and comfort throughout the mattress's lifetime.

Temperature Regulation and Breathability

A crucial aspect of a good night's sleep is temperature regulation and breathability. Coil mattresses tend to excel in this area due to the space between the coils, which allows for increased air circulation. The breathable nature of coil mattresses helps dissipate heat and moisture, keeping the sleep surface cool and comfortable. However, in hotter climates or for individuals who naturally sleep hot, coil mattresses may not provide sufficient heat dissipation. In such cases, opting for a spring mattress with pocket springs can be beneficial.

Spring mattresses, especially those with pocket springs, offer excellent temperature regulation. The individual pockets allow for air to flow through the mattress, promoting cooling and ventilation. This breathability prevents heat retention and ensures a comfortable sleep environment throughout the year. If temperature regulation is a top priority for you, a spring mattress with pocket springs can be an excellent choice.

Motion Isolation

Motion isolation refers to a mattress's ability to minimize and absorb movement, preventing it from transferring across the bed's surface. Coil mattresses, although they offer a comfortable sleep experience, may fall short in terms of motion isolation. As the coils are interconnected, any movement on one side of the bed can be felt on the other side, potentially disrupting the sleep of a partner who is more sensitive to motion.

On the other hand, spring mattresses, particularly those with pocket springs, excel in motion isolation. The individual pocket springs work independently, absorbing any movement and minimizing its transfer across the mattress. This feature is particularly advantageous for couples sharing a bed, as it ensures minimal sleep disturbance when one partner moves during the night.


In conclusion, the primary difference between coil and spring mattresses lies in their internal support systems. Coil mattresses utilize interconnected metal coils, providing a traditional bouncy feel and reliable support. On the other hand, spring mattresses, particularly those with pocket springs, offer targeted support, motion isolation, and enhanced temperature regulation.

When deciding between the two, it is essential to consider factors such as comfort, support, durability, temperature regulation, and motion isolation preferences. By understanding the differences between coil and spring mattresses, you can make an informed decision that meets your specific sleep needs and preferences. Remember to try out different mattresses, consider your sleep style and personal preferences, and consult with professionals to ensure you choose the best mattress for a comfortable, restful sleep.
