What is innerspring mattress?


An innerspring mattress is a type of mattress that is constructed with a system of metal coils or springs at its core. These coils provide support and help distribute the weight of the sleeper evenly across the mattress. Innerspring mattresses have been popular for many years and are known for their durability and affordability. In this article, we will explore the construction, materials used, and benefits of innerspring mattresses.

Construction of an Innerspring Mattress

Innerspring mattresses are typically made up of three main components: the coil system, comfort layers, and the mattress cover.

Coil System: The coil system is the foundation of an innerspring mattress. It consists of a series of metal coils or springs that are interconnected or individually wrapped. The coil gauge, which refers to the thickness of the wire used, can vary and affects the firmness and support of the mattress. The number of coils in a mattress can also vary, with more coils generally indicating better support and durability.

Comfort Layers: On top of the coil system, innerspring mattresses have comfort layers that provide cushioning and additional support. These layers can include materials such as foam, latex, or fiberfill. The thickness and type of comfort layers can vary between different models and brands, allowing for customization to suit individual preferences.

Mattress Cover: The outer layer of an innerspring mattress is typically a fabric cover that encases the coil system and comfort layers. The cover is designed to protect the mattress and provide a comfortable surface for the sleeper. It is often made of materials like cotton, polyester, or a blend of both.

Materials Used in Innerspring Mattresses

The materials used in innerspring mattresses can vary depending on the brand and model. Here are some common materials you may find in an innerspring mattress:

Coil Materials: The coils in an innerspring mattress are usually made of steel. The type of steel used can affect the durability and responsiveness of the mattress. High-quality innerspring mattresses often use tempered steel coils, which are heat-treated to enhance their strength and prevent sagging over time.

Comfort Layer Materials: The comfort layers in an innerspring mattress can be made of various materials. These may include memory foam, latex foam, polyurethane foam, or natural fibers like cotton or wool. Each material has its own unique properties, such as pressure relief, breathability, or temperature regulation.

Mattress Cover Materials: The cover of an innerspring mattress is typically made of a durable fabric that is breathable and easy to clean. Common materials used for mattress covers include cotton, polyester, or a blend of both. Some mattresses may also have additional features like cooling technologies or moisture-wicking properties in their covers.

Benefits of Innerspring Mattresses

Innerspring mattresses offer several benefits that make them a popular choice among consumers:

Support and Durability: The coil system in an innerspring mattress provides excellent support, helping to maintain proper spinal alignment. The durability of the coils ensures that the mattress retains its shape and support for an extended period.

Temperature Regulation: Innerspring mattresses have good airflow due to the open structure of the coil system. This allows heat to dissipate, preventing the mattress from trapping excessive body heat and keeping the sleeper cool throughout the night.

Edge Support: Innerspring mattresses often have reinforced edges, providing better support and preventing sagging when sitting or sleeping near the edge of the bed. This can be particularly beneficial for couples who need to utilize the entire surface of the mattress.

Affordability: Innerspring mattresses are generally more affordable compared to other types of mattresses, such as memory foam or latex. This makes them a popular choice for budget-conscious consumers who still want a comfortable and supportive sleep surface.


Innerspring mattresses are a popular choice for those seeking a supportive and affordable sleep surface. With their coil system, comfort layers, and durable mattress covers, they offer a combination of comfort, support, and temperature regulation. Whether you prefer a firm or plush feel, innerspring mattresses provide a wide range of options to suit different sleep preferences.
