Fun fact: You do not need a box spring with a hybrid mattress. This is a recurring question I see, and pocketed coils in hybrids eliminate the need for one. Box springs were designed to give more support and elevate performance to traditional coil beds, which would align certain sections of coils to yield more support. Nowadays, you may actually void your warranty if you use a box spring with a hybrid mattress—be sure to check that fine print.
Our favorite hybrid we've tested is the Helix Midnight Luxe, which happens to be our top overall pick in our best mattresses guide. It also utilizes pressure-relieving foams and pocketed coils to provide targeted lumbar support.
Another awesome hybrid mattress, the Nolah Evolution, seamlessly puts together some superb memory foam and pocketed coils, both of which counteract tension buildup for pressure points. I love it as an option for side sleepers for this reason, but it also works for back and stomach sleepers. The coils also make it easy to move around on, which is helpful for co-sleepers.
Innerspring
This is more of a history lesson than a type of mattress you want to shop for (unless you really love this kind of mattress; to each their own). “Traditional” innerspring mattresses are the firm-feeling beds you probably have early memories of, given that the makeup is just innerspring coils wrapped in a cover. It’s just as squeaky as you probably remember, too, as the coil type used involves connecting every coil to work as one unit.
These are Bonnell coils, and they connect both laterally and vertically. All to say, when you lie down and your weight is pressed into the mattress, all those coils act as “one for all and all for one” and simultaneously compress down. It’s not going to work wonders for pressure relief like modern hybrids will, but it is highly responsive, which means it’ll pop back into its original shape as you move around. So if you’re a sleeper who moves around between sleeping positions, coils are a good feature to have, so you’re getting near-instantaneous support.
Why aren't traditional coils in the works with mattresses nowadays? According to Merwin, upgraded pocketed coils far outperform traditional ones. “Unlike traditional coils that are wired together and move as a unit, pocketed coils are encased individually, which allows each coil to respond independently to movement and pressure," he said. "This design minimizes motion transfer, so when one person moves or gets out of bed, their partner feels far less disruption. It also provides more targeted support, contouring to the body in a way that improves spinal alignment and overall comfort.” While you can still find innerspring mattresses with traditional coils out there, they're typically getting phased out in favor of hybrids. Truth be told, I've only tested less than a handful of them over the years. If you're dead set on this mattress type, all power to you, and have fun on your personal mattress treasure hunt.
The Saatva Classic is one of those modern, rarer beds that rely on traditional coils in the secondary coil layer on the very bottom of the bed. This is to help with overall durability and support, which WIRED tester Nena Farrell has mentioned could be beneficial for those with back pain.
Memory Foam
We actually have NASA to thank for this one. If you google images of those early space missions, it’s no wonder that something was needed to keep astronauts from being jostled around inside rockets; hence, memory foam was born. It’s evolved quite a bit from those initial iterations, especially when Tempur-Pedic came onto the scene in the ’80s with a vision for it to become the basis of sleep products. Today, memory foam stands in a league of its own when it comes to the unique, compressive feel.
