An innerspring mattress is a type of mattress that uses coils (springs) inside its construction to provide support. These coils are typically made from steel and are the primary support structure, with layers of padding or foam placed on top to add comfort. Innerspring mattresses are known for their durability, support, and responsiveness. The coils are usually arranged in a grid pattern, and there are different types of coil systems such as Bonnell coils, continuous coils, and pocketed coils. Pros of innerspring mattresses: Good support for back and spine alignment. Typically cooler due to airflow between the coils. Available in a wide range of firmness options. Generally more affordable than memory foam or hybrid mattresses. Cons: Can be noisy due to coil movement over time. Less durable than memory foam or hybrid mattresses (with sagging occurring more quickly). May not provide as much pressure relief for people with specific comfort needs.
