Innerspring vs. Polyurethane Foam

Innerspring

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.

Polyurethane Foam

Polyurethane foam is a blanket term that includes any foam that is synthesized using polyol and diisocyanate. These include but are not limited to: memory foam, high resilience foam, and high density foam. Since polyurethane foam can contain additives, a manufacturer that comes up with a new formula can name the new foam whatever they like.

Many memory foam mattresses are a combination of polyurethane foams, layered from dense on the bottom to less dense on the surface layers.

Polyurethane is a synthetic blend of organic compounds and has a tendency to off-gas. If you are susceptible to lung issues, please do additional research on the quality of foams before purchasing.

Pros: Many different types of foams exist under the polyurethane umbrella -- some are excellent for bedding and offer different firmness varieties!

Cons: Off-gassing and durability problems with lower quality foams.
