Coil springs are the most common type of springs used in mattresses. They are made of steel coils that are connected together to form a sturdy and supportive base for the mattress. The number of coils and the type of coil used can greatly affect the overall comfort and support of the mattress. There are several types of coil springs used in mattresses, each with its own unique benefits. Some of the most popular types include Bonnell springs, continuous coils, offset coils, and Marshall coils. Let's take a closer look at each one and see how they contribute to creating the perfect mattress.Coil Springs
Bonnell springs, also known as open coils, are the oldest and most widely used type of coil springs in mattresses. They are made of hourglass-shaped coils that are connected together with spiral wires. Bonnell springs are known for their durability and affordability, making them a popular choice for budget-friendly mattresses. However, they may not provide as much support and motion isolation as other types of coil springs.Bonnell Springs
Continuous coils, also known as Mira-Coil or Multi-Coil, are made of a single long wire that is shaped into multiple coils. This design allows for a more stable and supportive surface, as the coils are all connected and work together to distribute weight evenly. Continuous coils are also known for their motion isolation, making them a great choice for couples who don't want to be disturbed by their partner's movements during the night.Continuous Coils
Offset coils are similar to Bonnell springs in shape, but they are designed with a flat top and bottom to provide more surface area for support. This type of coil is known for its ability to contour to the body and provide targeted support where it is needed most. Offset coils are often used in higher-end mattresses and can provide a good balance of comfort and support.Offset Coils
Marshall coils, also known as pocketed coils, are individually wrapped coils that are placed inside fabric pockets. This allows each coil to move independently, providing targeted support to different parts of the body. Marshall coils are known for their ability to reduce motion transfer and provide a more customized level of support. They are often used in luxury mattresses and can be combined with other types of support systems to create a hybrid mattress.Marshall Coils
The wire gauge of a coil spring refers to the thickness of the wire used to make the coils. A lower gauge number means a thicker wire, which typically results in a firmer and more supportive mattress. A higher gauge number means a thinner wire, which can provide a softer and more conforming feel. The ideal wire gauge for a mattress depends on personal preference and body weight, but a good rule of thumb is to look for a mattress with a gauge between 12 and 15.Wire Gauge
The number of coils in a mattress, also known as the spring count, can greatly affect the overall support and comfort of the mattress. A higher spring count does not necessarily mean a better mattress, as other factors such as the type of coil and wire gauge also play a role. However, a mattress with a higher spring count may provide more support and durability over time. It is important to find a balance between spring count, type of coil, and wire gauge to create the perfect mattress for your needs.Spring Count
Spring tension refers to the amount of force needed to compress a coil spring. This can greatly affect the overall feel of the mattress, as a higher spring tension will provide a firmer and more supportive surface, while a lower spring tension will feel softer and more plush. The ideal spring tension for a mattress depends on personal preference and body weight, but a good rule of thumb is to look for a mattress with a medium spring tension for a balance of comfort and support.Spring Tension
The spring system of a mattress refers to how the coils are arranged and connected. Some mattresses use a traditional innerspring system, where all the coils are connected and work together to provide support. Others use a pocketed coil system, where each coil moves independently to provide targeted support. Hybrid mattresses may use a combination of different spring systems to provide the best of both worlds. The spring system of a mattress can greatly affect its overall feel and level of support, so it is important to consider this when choosing a mattress. In conclusion, the type of spring used in a mattress is an important factor to consider when looking for the perfect bed. Each type of coil has its own unique benefits, and finding the right combination of coil type, wire gauge, spring count, and spring tension can result in a mattress that provides both comfort and support for a restful night's sleep.Spring System
