The coil count of a spring mattress refers to the number of coils or springs that make up the support system. This is an important factor to consider when choosing a spring mattress as it directly affects the level of support and comfort. Generally, the higher the coil count, the better the support and the more durable the mattress will be.Coil Count
One type of coil system found in spring mattresses is pocketed coils, also known as individually wrapped coils. These coils are individually encased in fabric pockets, allowing them to move independently. This provides better support and reduces motion transfer, making it a popular choice for couples. Additionally, pocketed coils conform to the body's shape, providing a more personalized level of comfort.Pocketed Coils
Bonnell coils, also known as open coils or hourglass coils, are the oldest and most common type of coil system found in spring mattresses. They are hourglass-shaped and are connected by wires, providing a bouncy and supportive feel. However, this type of coil system may not be as durable as others and may produce more noise and motion transfer.Bonnell Coils
Continuous coils, also known as Mira-Coil, are made from a single long wire that is formed into multiple S-shaped coils. These coils are connected in a continuous row, providing more stability and support compared to Bonnell coils. They also have a higher coil count, making them more durable and able to withstand more weight.Continuous Coils
Offset coils are similar to Bonnell coils in shape, but they have a more squared-off top and bottom. They are connected by helical wires, providing a more responsive and conforming support. This type of coil system is known for its durability and can provide a comfortable and supportive sleep experience.Offset Coils
The wire gauge of the coils refers to the thickness of the wire used to make the coils. A lower gauge number indicates a thicker wire, resulting in a firmer and more supportive feel. On the other hand, a higher gauge number means a thinner wire, resulting in a softer and more plush feel. The ideal wire gauge for a spring mattress depends on personal preferences and body weight.Wire Gauge
Aside from the traditional hourglass shape, coils can also come in other shapes such as cylindrical or barrel-shaped. These shapes can provide more targeted support for specific areas of the body, such as the shoulders and hips. Some mattresses may also have a combination of different coil shapes for a more customized level of support.Coil Shape
Coil gauge refers to the thickness of the wire used to make the coils and is usually measured in millimeters. A lower gauge number means a thicker wire and a firmer feel, while a higher gauge number means a thinner wire and a softer feel. It is important to choose a coil gauge that can adequately support your body weight for a comfortable and restful sleep.Coil Gauge
Coil density refers to the number of coils per square foot in a spring mattress. It is often used interchangeably with coil count but is a more accurate measure of the support and durability of a mattress. A higher coil density means more coils are used, providing better support and reducing the risk of sagging over time.Coil Density
The coil support system refers to the structure and arrangement of the coils within the mattress. There are various types of support systems, such as foam encased, zoned, and reinforced, which can affect the overall feel and support of the mattress. It is important to choose a support system that can provide the right level of support for your body and sleeping preferences.Coil Support System
