If you’re looking To buy a mattress, I don’t need to tell you that the research process is complicated. To assist with this, we have a whole guide (not intended… OK, partially intended) where to start. But now, I’m going to browse all kinds of mattresses Material. My hope is that when you read this article you will have a better understanding of the mattress you want, which will make your final decision easier.
For peace of mind, let me allow you to qualify: I am a certified sleep science coach and mattress tester for over five years. I can dissect the mattress blueprint faster than pouring morning coffee, and I have perfected my unboxing form (because the mattress is Heavy), I can recite the manufacturing process of the main mattress material at any given moment. It’s a fun party trick, but it makes me think about being the ultimate boss of the mattress test. My teammates also know their stuff (we slept on mattresses for a week or more and then reported our findings), which helped us compile this list of the best mattresses of 2025.
So, go back to picking a mattress: While the mattress in the box and its images projected in our minds are popular, it’s much more than the rectangular foam you’re sleeping with. There are four main types of mattresses: internal springs, hybrids, memory foam and latex. To help me explain the material more, I asked John Merwin, CEO of 3Z Brands (parent company of Helix, Birch, Bear, Nolah and Leesa), who is also the founder of Brooklyn Bedding, to join the weight.
Innerspring
To be honest, it’s more of a history class than a mattress to buy (unless you really like this one; everyone will do it themselves). The “traditional” interior spring mattress is a solid bed you might have for early memories, as the makeup is just an internal spring coil wrapped around the cover. It’s just as squeaky as you might remember, as the type of coil used involves connecting each coil to a unit.
These are Bonnell coils, which are connected transversely and vertically. All said that when you lie down and press the weight into the mattress, all of these coils act as “all, one person for all” and compress at the same time. It doesn’t do the miracle of stress relief like a modern hybrid, but it responds quickly, meaning it pops out of its original shape as you move. So if you are a sleeper walking around between sleeping positions, the coil is a great feature, so you get nearly practical support.
Why are there no traditional coils on mattresses today? According to Melwin, upgraded bagged coils far outweigh traditional coils.
“Joined together with traditional coils and moved as a unit, the bagged coils are wrapped individually, which allows each coil to respond independently to motion and pressure,” he said. “This design minimizes movement transfer, so when a person moves or gets up, their partner feels much more disruptive. It also provides more targeted support in a way that improves spinal alignment and overall comfort to the body.” While you can still find internal spring mattresses with traditional coils, they are often phased out to support hybrids. To be honest, I’ve only conducted less than a few tests over the years. If you’ve been on this mattress type, that’s all your power and have fun in your personal mattress treasure hunt.
Hybrid
Traditional coil mattresses have evolved into hybrids, which you might encounter in today’s mattress market (apart from latex and foam options). The hybrid mattress is highly customizable and allows you to choose what you want in your bed, whether it’s a combination of foam and coil, latex and coil, or a mixture of three. Many mattress reviews will use the term “the best of both worlds” to describe hybrid power, as this mattress allows you to taste the design aspects of the materials involved. You can get the required pressure relief from the top memory foam or latex, but the coil core is enough to support (not to mention the above responsiveness the coil contains).
Speaking of coils and back to traditional mattress designs, the type of coil used in hybrid mattresses is also important because it improves on the design of the Bonnell Coil. The keywords to be found are “bagged coils” or “single-wrapped coils”, which form the main support mechanism of the mattress. Each coil stays on its own lane (actually a pocket) and is not interconnected, but is compressed by other coils around it. In other words, if you weigh more, the bed will feel stronger.
This is especially suitable for areas where weight is concentrated when lying down, especially on the hips and shoulders. The coils of the pocket are also designed to go beyond the traditional coils in the field of motion isolation, which means that when you move around, a single coil takes heat movement and prevents the bed from remaking small earthquakes. With the interconnectivity of traditional coils, there is not much motion feeling when traveling along the entire bed surface.
