Why Do Mattresses Have Springs? - Megafurniture

Why Do Mattresses Have Springs?

Mattresses have changed a lot over time. They started as simple bags filled with straw and turned into the soft and comfy beds we have now. But one interesting thing about modern mattresses is that they have springs inside. These are like coiled-up pieces of metal hidden under the soft stuff you lay on that become a big part of why our beds are comfortable.

But have you wondered why mattresses have springs? What purpose do they serve, and how have they transformed our sleeping comfort? In this article, we will discuss why mattresses have springs, shedding light on the secrets hidden beneath our nightly slumber.

The Introduction of Springs to Mattresses

The Introduction of Springs to Mattresses

Springs were introduced into mattresses during the 19th century as an innovative solution to address the limitations of earlier materials. Springs significantly improved mattress design by offering better support, comfort, and durability compared to traditional materials, making them a game-changer in the world of bedding.

Springs offer improved support by distributing weight evenly and conforming to the body's contours, leading to better spinal alignment, reducing pressure points, and making mattresses more comfortable for sleepers. Springs enhance mattress longevity and resilience, reducing issues like sagging over time. Furthermore, springs contribute to breathability by allowing air circulation within the mattress, helping regulate temperature during sleep and ensuring a more comfortable night's rest.

Types of Spring Mattresses

Innerspring Coils

Innerspring mattresses feature a network of steel coils or springs that provide support and bounce. These coils come in various configurations, such as Bonnell coils (hourglass-shaped), offset coils (hourglass with flattened tops and bottoms), and pocketed coils (individually encased in fabric pockets). Innerspring mattresses are known for their durability and good airflow, making them a popular choice for many.

Continuous Coils

Continuous coil mattresses are a single wire twisted into a series of S-shaped coils. This design offers consistent support throughout the mattress and can be more cost-effective than individually pocketed coils. However, they may not contour to the body or other options.

Pocketed Coils (Pocket Springs)

Pocketed coil mattresses contain individual coils that are encased in fabric pockets and each coil moves independently to better conform to the body's shape and reduce motion transfer. This design is excellent for couples or those looking for enhanced pressure relief.


How Springs Affect Mattress Comfort?

How Springs Affect Mattress Comfort


Springs provide the foundational support for your body while you sleep. The level of support is determined by the type and arrangement of springs within the mattress, and proper support helps maintain a neutral spinal alignment, reducing pressure points and ensuring a comfortable sleep posture. Innerspring and pocketed coil mattresses, for example, are known for their excellent support due to the resilient nature of their coil systems.


The gauge (thickness) of the springs and their arrangement can influence the firmness of a mattress. Thicker coils or a higher coil count generally result in a firmer mattress, while thinner coils or a lower coil count can make a mattress feel softer.

Motion Isolation

Springs also affect how well a mattress isolates motion. In traditional innerspring mattresses with interconnected coils, movement on one side of the bed can be felt on the other, which may disrupt sleep for couples. Pocketed coil mattresses, on the other hand, excel in motion isolation because each coil moves independently, reducing the transfer of motion from one side of the mattress to the other.


The quality and durability of the springs themselves impact how long the mattress maintains its comfort. High-quality springs made of durable materials can ensure the mattress retains its support and comfort characteristics for an extended period.

Temperature Regulation

Springs contribute to a mattress's breathability. Innerspring mattresses allow for better airflow than all-foam mattresses, promoting better temperature regulation during sleep, which can be especially important for individuals who tend to sleep hot.


Drawbacks of Spring Mattress

Drawbacks of Spring Mattress

Motion Transfer

Innerspring mattresses can transmit motion across the bed. When one person moves or gets in and out of bed, their partner may feel the motion, potentially leading to sleep disturbances for couples.

Less Conforming Comfort

Spring mattresses may not conform as closely to the body's contours as foam or latex mattresses, leading to pressure points and discomfort, especially for those with specific pain issues or who prefer a more cushioned feel.

Limited Lifespan

While durable, spring mattresses have a shorter lifespan than other mattress types. Over time, the coils may lose their resilience, reducing support and comfort.


Some innerspring mattresses can be noisy because over time, the coils may creak or squeak with movement, disrupting sleep.


Spring mattresses may require occasional flipping or rotating to maintain comfort and even wear and tear.

Allergens and Dust

The open design of spring mattresses can allow allergens, dust mites, and other particles to accumulate inside the mattress, which can be problematic for individuals with allergies or asthma.

Edge Support

Edge support can vary in spring mattresses, and some models may lack strong edge support, making it uncomfortable to sit or sleep near the edge of the bed.


Spring mattresses are often heavier than foam or latex mattresses. This weight can make them more challenging to move or handle.


Why are springs used in mattresses?

Springs are used in mattresses to provide support, comfort, and durability. They help distribute weight evenly, reduce pressure points, and maintain the mattress's shape over time.

How do springs in mattresses affect sleep quality?

The presence of springs can impact sleep quality by offering support, reducing discomfort, and allowing for proper spinal alignment, resulting in a more restful night's sleep.

Do all mattresses have springs?

Not all mattresses have springs. Some mattresses, like memory foam or latex mattresses, use different materials for support and comfort.

What is the role of springs in mattress firmness?

Springs play a significant role in determining the firmness of a mattress. Different coil types, arrangements, and gauges can result in varying firmness levels.

Are spring mattresses good for people with back pain?

Spring mattresses can be a good choice for people with back pain, as they offer support and help alleviate pressure on the back. However, the right firmness level is essential and varies by individual.

Why I can feel springs through mattress?

Feeling springs through a mattress can occur due to factors such as mattress age, quality of materials, weight distribution, mattress design, and individual body sensitivity.

How often should I replace a spring mattress?

The lifespan of a spring mattress can vary depending on factors like quality and usage, but on average, they may last around 7-10 years. Regularly assessing your mattress for signs of wear can help determine when it's time for a replacement.


Spring Mattress

Springs in mattresses are like the strong foundation that keeps everything comfortable. They are the unsung heroes beneath the layers of fabric and foam, diligently working to provide us with the support and rest we need. Springs have played a crucial role in bedding, from their humble beginnings as an answer to the shortcomings of earlier bedding materials to their evolution into various types of coils designed for different sleep preferences. While other mattress materials have gained popularity in recent years, springs continue to hold their place as a trusted and time-tested option for those seeking a good night's sleep. So, the next time you lie down on your mattress, take a moment to appreciate the subtle but vital presence of springs beneath you, ensuring your restful slumber night after night.
