To put your mind at ease, let me guide you through my credentials: they are a Coach of Certified Sleep Sciences and Tester mattress of over five years. I can dissect a mattress project faster than pouring your cup of morning coffee, I have perfected my form of unboxing (because the mattresses are heavy) and I can recite the production process of the main materials of the mattress at any time. It’s a funny festive trick, but it makes me what I like to think like the final boss of the mattress tests. My teammates also know their things (we sleep on the mattresses that we test for a week or more, so they report on our results), which helped us to fill in this list of the best mattresses of 2025.
So, returning to choose a type of mattress: despite the popularity of the mattresses in a box and the image they project in our heads, it is much more than a piece of rectangular foam on which you sleep. There are four main types of mattresses: hole, hybrid, memory foam and latex. To help me explain these materials even more, I asked John Merwin, CEO of 3z Brands (Madre of Helix, Birch, Bear, Nolah and Leesa) and founder of Brooklyn Letting Handing, to weigh.

To tell the truth, this is more a history lesson than a type of mattress for which you want to buy (unless you really love this type of mattress; to each one). The “traditional” hole mattresses are the beds that probably have the first memories, given that the makeup is only coils for injunations wrapped in a cover. It is equally creaking as it probably also remember how the type of coil used involves the connection of each coil to work as a unit.
These are bobins Bonnell and connect both laterally and vertically. All to say, when you lie down and your weight is pressed in the mattress, all those coils behave like “one for all for one” and at the same time compresses. It will not make miracles for a relief with pressure as modern hybrids will do, but it is highly reactive, which means that it will return to its original form while you move. So, if you are a sleeping that moves between sleep positions, the coils are a good feature to have, so you are getting an almost instant support.
Why are traditional coils nowadays now in work with mattresses? According to Merwin, the updated coils far exceed the traditional ones.
“Unlike the traditional coils that are wired together and move as unit, the coats Intascarano are enclosed individually, which allows each coil to respond independently to movement and pressure,” he said. “This design minimizes the transfer of movement, so when a person moves or gets up from the bed, their partner feels much less interruption. It also provides a more targeted support, the outline of the body in order to improve spinal alignment and general comfort.” While still can find hole mattresses with traditional coils out there, they are generally eliminated in favor of hybrids. To tell the truth, I only tested less than a handful over the years. If you died on this type of mattress, all the power for you and have fun on your treasure hunt for the personal mattress.
Hybrid
Traditional coil mattresses have evolved into hybrids, which is what you probably meet on the market of today’s mattresses (apart from latex and foam options). The hybrid mattresses are highly customizable, allowing you to choose what you want in your bed, whether it is a combination of foam and coils, latex and coils or even a mix of three. Many mattress reviews will use the “Best of Exclue Worlds” phrase to describe hybrids, since this mattress allows you to taste the aspects of the design of the materials involved. You can get relief from the pressure you need from the memory foam or latex to the top, but a broad support from the nucleus of the coil (not to mention the aforementioned reactivity from the inclusion of the coil).
Speaking of coils and returning to the traditional mattress design, the type of coil used in hybrid mattresses is also important, since it improves the design of the Bonnell coil. The keywords to look for are “pocket coils” or “individually enveloped coils”, which constitute the main support mechanism of a mattress. Instead of being interconnected, each coil remains in its own lane (pocket, really) and will compress uninhibited by the other coils that surround it. In other words, where there is more weight, the bed will feel more solid.
This is particularly applicable for areas where body weight is centralized when you are lying down, in particular around the hips and shoulders. The coils in your pocket are also designed to overperform traditional ones in the arena areolation of the movement, which means that when you move, the single coil takes the heat and prevents the bed from recalling a small earthquake. With the interconnectivity of traditional coils, it does not take much so that the feeling of travel movement along the entire surface of the bed.
