Memory foam has come a long way from the ’70s. With advancements in both sleep science and production processes, mattress experts have found new and innovative ways to hone in on memory foam benefits for a wide range of sleepers. It can be divided chiefly into three main categories:Traditional Memory Foam: Original foam contains a closed-cell structure, which can result in stuffy sleep if you’re a hot sleeper. The feel of traditional memory foam is often compared to that of a pillow, and it has all the body-contouring properties that make it a great choice for sleepers with chronic pain.Open-Cell Memory Foam: One way to think of open-cell foam is by comparing it to the cross-section of a sponge - there are many tiny passageways that ensure air is circulated properly, making sure your mattress remains well-ventilated. This type of foam is usually less dense than its traditional counterpart, so they’re often used on softer-feeling mattresses.Gel-Infused Memory Foam: An innovative solution to the problem of temperature, gel-infused memory foam involves pumping microbeads into the polyurethane, thereby enabling pockets that are similar to the ones in open-cell foam. These microbeads actively work to absorb and release heat from your body, keeping you cool through the night.The mattress industry is fast-evolving and constantly improving upon itself. From copper-infused foam that is made to dissipate heat, to eco-friendly foams that incorporate plant-based materials, there’s no shortage of options out there in the market.This makes it all the more important to assess the quality of your mattress provider properly and ensure you’re getting as much as you can when you invest in a mattress.
