What is an Innerspring Mattress? Invented in 1871, the innerspring is what most people think of when they think “traditional mattress.” Think of brands like Serta Simmons, and other long-standing brands available in most brick and mortar stores. They are a mattress constructed with a layer of coils as their support and do not have a lot of material on top of those coils, making them very firm options.
Are innerspring mattresses firm? In short, yes. They tend to be some of the firmest options on the market since they typically do not have a comfort layer overtop the coil base. While there have been many improvements to innerspring mattresses since their creation, they are still not hailed as the most comfortable or pressure-relieving models.
