Coil spring (also called innerspring) mattresses use metal coils to provide resistance and support. Contemporary bedding use pocket coil systems that are entirely independent from each other so there are less pressure points. The rule of these new pocket coil systems is the more coils that are used, the more independent movement and response is in mattress.
Older coil spring mattresses, however, have one frame with coils interconnected to one another. Although this provides good support across the entire surface, and a longer durability life, there are comfort concerns about these mattresses.
Additionally, most coil spring mattresses have memory foam, latex, or some other type of bedding to provide a soft surface to sleep on.
Pros: Durable materials, and newer pocket coil systems provide comfortable support.
Cons: Older coil spring mattresses can cause more back pain and irritate pressure points.
Innerspring systems describe mattresses made with coil systems. Traditional innerspring mattresses were made with interconnected coils, providing structure to the bed. In recent years, some have used 'innerspring' to describe newer pocket spring systems that are independent and offer greater comfort.
In general, most use 'innerspring' to describe the traditional mattress styles and those that purchased a mattress in the 20th century are very used to these types of beds.
The interconnected spring systems offer a high amount of durability and support, but there are complaints of aggravated pressure points and discomfort despite comfort layers of foams on the surface.
Pros: Durable materials and traditional even feel.
Cons: Pressure point discomfort and motion transfer issues.
