If you have the space, a king-sizeis a no-brainer, especially if you have to share your bed with someone else (or your pets). Of course, king-size mattresses give you extra room to move around freely, but the additional space is also beneficial for helping to relieve pressure on your body and allowing you to sleep comfortably.
Whether you're looking to upgrade to a king-size mattress, or you need to swap out your current model for something with more modern advancements, I've got you covered. I tried more than two dozen mattresses to find the best king mattresses out there. From hybrid mattresses to polymer grids to advanced gel technology, these are my favorites.
The Nectar Lush is my top pick for pressure relief and edge-to-edge support. It's made of five layers -- including a dense foam base, a high-density memory foam, a gel-coated memory foam and a cooling cover -- that really work well together. As soon as I laid down on the mattress, the foam layers started to adapt to my body and "hug" it in a way that made me feel fully supported and properly aligned. After sleeping on the Nectar Lush for a few weeks, I felt a noticeable difference in my pain levels, immediately upon waking up and throughout the day.
And this was true no matter how close to the edge I got -- there was no sagging or dipping at all. The memory foam was also really responsive and didn't have that slow sinking feeling that's common with many memory foam mattresses. When I changed sleeping positions at night, the mattress was quick to react and adapt to my body so that I felt comfortable right away and could quickly drift back off to sleep.
The Helix Midnight Luxe mattress is one of Helix's most popular models and, after testing, it's apparent why. The mattress is made from a combination of high-density memory foam, gel visco and support pocketed coils wrapped up in a breathable, quilted pillow-top cover, making it a true hybrid model. Out of all the mattresses I tested, the Helix Midnight Luxe had the most lumbar support, which really provided some relief for my boyfriend's chronic lower back pain. It also took the least amount of getting used to. It felt comfortable almost immediately.
Although this particular mattress is marketed toward the side sleeper, it's comfortable for all sleep positions -- I often sleep on my back too. There's almost no motion transfer and it falls smack in the middle of the mattress firmness scale -- Helix rates it a 4 to 7 out of 10 -- so it's designed to please everybody, or at least serve as a really great compromise if you're sleeping with someone else and can't agree on firmness level.
Rather than varying layers of memory foam, the Purple Hybrid Premier 4 has a hyperelastic polymer grid formation that's meant to absorb and relieve pressure, no matter how you sleep. It seemed to have this magic ability to form around my body and perfectly cradle my pressure points, which not only made it immediately comfortable, but also had me waking up totally pain-free.
The Purple also had the most bounce out of all of the mattresses, so if you're looking for something that's more reminiscent of a traditional spring bed, but without the noisiness and eventual breakdown, this is an excellent option. Coming from memory foam, the grid did take a little while to get used to. It wasn't uncomfortable, but it was definitely different, so keep that in mind. There's an adjustment period with any new mattress, though, so it's not something that was totally unexpected.
The Leesa Legend was designed for all types of sleeping positions, but it's a standout pick for back sleepers. The mattress is categorized as medium-firm, but it felt plush enough to appease soft mattress lovers too. Sometimes I find memory foam too firm, but I sank into the Leesa Legend in all of the best ways. And since it has two layers of springs in addition to two layers of memory foam, it provided the right balance of body contour and support to keep my spine aligned without any sinking. Like the Nectar Lush, it also had excellent edge-to-edge support and minimal motion transfer.
The 100% organic cotton and Merino wool cover was also a really nice touch. Not only did it feel soft and inviting, it's designed to wick away moisture, so you stay cool and dry while you sleep. And it's made from recycled water bottles, which is really cool.
The Saatva Classic combines innerspring coils with latex foam, making it a true hybrid mattress, but it has enhancements that are designed to reduce stress and tension in your back. The middle portion of the mattress has "lumbar zone technology," or a series of wires that add extra support for the memory foam to keep your spine properly aligned, especially when you're sleeping on your side.
Although I didn't love this mattress initially, after sleeping on it for a few nights, it quickly became one of my favorites. It was firm enough that I felt properly supported, but, thanks to some extra plushness and thickness from the pillow top, it also felt softer than other similar mattresses. The only knock is that this mattress has more motion transfer than the others, so if you sleep with someone who moves around during the night, there's a good chance you're going to feel it.
Let's address the elephant in the room right away: This mattress is expensive. But if you have the budget and you're looking for a way to invest in your quality of life, you won't be disappointed. The Intellibed Signature Matrix Grand is constructed of several layers, including latex and foam, but the real star of the show here is the Gel Matrix technology -- something that was originally used in the beds in burn units to help alleviate pain while patients recovered.
Without getting too technical, the Gel Matrix is an elastic gel that flexes and moves so that it's somehow firm and soft at the same time, giving you the best of both worlds. The firmness provides the support your body needs and keeps your spine in the proper alignment, while the softness allows some give to relieve your pressure points without sagging. And it truly does work.
When lying on the mattress, I felt it give to my pressure points -- namely, my shoulders and hips -- while still keeping my body properly aligned, no matter which position I was in. As soon as I got comfortable in it, I could feel the pressure lifting away, almost as if I was in a zero gravity situation and, after a few weeks with it, I realized I was sleeping through the night consistently.
It's also the first mattress that my boyfriend and I wholeheartedly agreed on. There were others that we both really liked, like the Helix Midnight Luxe and the Purple Hybrid Premier 4, but the Intellibed Signature Matrix Grand has completely squashed all mattress discussions and, to me, that alone is worth the price.
