Innerspring mattresses are a traditional and widely recognized type of mattress that feature a core support system made up of metal coils or springs. These coils provide a supportive foundation for the mattress, promoting proper spinal alignment and distributing body weight evenly. Innerspring mattresses often have additional layers of padding, such as foam or fiberfill, to enhance comfort and cushioning. One of the key advantages of innerspring mattresses is their excellent breathability, allowing for increased airflow that helps regulate temperature during sleep. The coil system also provides a responsive feel, offering a bouncy surface and good edge support. Innerspring mattresses are available in a range of firmness levels, making them suitable for various sleep preferences. They have a longstanding reputation for durability, as well as affordability compared to some other mattress types. Innerspring mattresses are a popular choice for individuals who prefer a more traditional sleep surface with reliable support and responsiveness.
