A vital component of a spring mattress is the coils. These metal springs provide the support and structure to the mattress, allowing it to contour to your body and relieve pressure points. The quality and quantity of coils can greatly affect the comfort and durability of a spring mattress. Most spring mattresses use either bonnell coils or pocketed coils. Bonnell coils are hourglass-shaped and connected together with spiral wires, while pocketed coils are individually wrapped in fabric pockets. Pocketed coils provide better motion isolation and support compared to bonnell coils.Coils
The support system of a spring mattress refers to the layer of coils or springs that provide the main support for your body. This layer is responsible for distributing your weight evenly and maintaining proper spinal alignment while you sleep. Some mattresses use a zoned support system, where the coils are arranged in different zones to provide varying levels of support for different areas of the body. This can be especially beneficial for those who experience back pain or other body aches.Support System
The term "innerspring" refers to the type of coils used in a spring mattress. These coils are typically made from tempered steel and are designed to provide support and durability. Innerspring mattresses are known for their bouncy and responsive feel, making them a popular choice for those who prefer a more traditional mattress. There are different types of innerspring coils, including continuous coils and offset coils. Continuous coils are connected in a single piece, while offset coils are hourglass-shaped and connected with helical wires. Both types offer good support and motion isolation, but offset coils may be better at contouring to the body.Innerspring
The border rod is a supportive metal rod that runs around the edge of the mattress. This serves as a reinforcement, preventing the mattress from sagging and providing a stable edge for sitting or getting in and out of bed. The border rod is especially important for larger or heavier individuals, as it helps to distribute their weight evenly and prevent the edges of the mattress from collapsing or sinking.Border Rod
Edge support refers to the reinforcement around the edges of the mattress, which helps to maintain the overall shape and structure of the mattress. This is particularly important for spring mattresses, as they can be prone to sagging and losing their shape over time. Some mattresses have enhanced edge support, such as foam encasement, which utilizes a layer of foam around the perimeter of the mattress for added stability and support.Edge Support
The foundation, also known as the box spring, is the base of the mattress that provides additional support and stability. It is typically made from wood or metal and is designed to absorb shock and reduce wear and tear on the mattress. The foundation also helps to distribute weight evenly, preventing excessive pressure on certain areas of the mattress and extending its lifespan.Foundation
The comfort layer is the top layer of the mattress, providing cushioning and contouring to the body for a comfortable sleep surface. In a spring mattress, the comfort layer is usually made from materials such as foam, latex, or fiberfill. The type and thickness of the comfort layer can greatly affect the overall feel of the mattress, with thicker and softer layers providing a more plush and luxurious feel.Comfort Layer
The insulator pad is a layer of material that sits between the comfort layer and the coils, preventing them from poking through or causing discomfort. This layer can also help to reduce noise and motion transfer, making for a more peaceful and undisturbed sleep. The insulator pad is typically made from materials such as cotton, wool, or synthetic fibers.Insulator Pad
The quilted cover is the top layer of the mattress, providing a soft and comfortable surface for sleep. It is typically made from a combination of materials, such as cotton, polyester, or rayon, and is quilted to create a plush and even surface. Some mattresses have a tufted cover, where the layers of the mattress are held together with buttons or stitches, creating a firmer and more supportive feel.Quilted Cover
A pillow top is an additional layer of cushioning added to the top of the mattress, providing extra comfort and plushness. It can be made from various materials, such as memory foam, latex, or fiberfill, and is designed to give the mattress a softer and more luxurious feel. The pillow top can vary in thickness and can be found on both innerspring and hybrid mattresses.Pillow Top
