Steel Coils
The most important component of an innerspring mattress is the steel coils, which provide the support and comfort. The coils are made of tempered steel, which is heat-treated for extra strength and durability. The coils are arranged in a variety of patterns, such as the Bonnell coil, the offset coil, and the pocket coil. The Bonnell coil is the most common type of coil, and it features an hourglass shape that is connected at the top and bottom. The offset coil is similar to the Bonnell coil, but it is offset at the top and bottom to provide extra support. The pocket coil is a newer coil design, and it is made up of individual coils that are encased in fabric pockets.
Foam
Foam is often used in innerspring mattresses to provide additional comfort and support. Foam is a soft, cushioning material that is made from polyurethane, memory foam, or latex. Memory foam is a popular choice for innerspring mattresses because it conforms to the shape of the body and provides pressure relief. Latex foam is another popular choice because it is naturally breathable and hypoallergenic.
Cotton
Cotton is a natural material that is often used in innerspring mattresses to provide a soft and comfortable sleeping surface. Cotton is breathable and hypoallergenic, and it helps to regulate body temperature. It is also resistant to dust mites and other allergens, making it a popular choice for allergy sufferers.
Edge Support
Edge support is an important feature of an innerspring mattress because it helps to support the edges of the mattress and prevents sagging. Edge support is usually made from foam or a combination of foam and steel. Some mattresses also have reinforced edges that are designed to provide extra support.
Innerspring mattresses are a great choice for anyone looking for comfort and support. They are available in a variety of sizes and firmness levels, and they are made from a combination of steel coils, foam, cotton, and latex. Innerspring Mattresses are also known for their edge support, which helps to prevent sagging and provide a more comfortable sleeping surface.
