Beds didn’t used to be this complicated. But these days, there are mattresses built for all shapes and sizes, and thanks to the wide variety of materials, manufacturing methods, and philosophies, there are so many more options beyond the bed you grew up with.
Helix and Purple are two very good examples of how different a mattress can be. One feels very familiar, with contouring foam, supportive coils, and predictable comfort. The other is starkly bouncy, floaty, and oddly supportive in spots you didn’t expect.
Helix is built around getting your comfort right from the start. You take a quiz, pick a model, and land on something that matches your sleep style. It’s very much about dialing in that classic support and cushion balance most people expect from a mattress.
Purple comes at it from the opposite direction. It assumes that maybe the traditional mattress feel isn’t actually perfect, and it tries to solve pressure relief, airflow, and movement in a completely new way.
So the real question becomes: Are you trying to improve something you already understand and like the feel of, or are you looking for something entirely new?
At a Glance
| Helix | Purple | |
| Overall feel | Traditional hybrid (foam and coils) | Unique Grid (GelFlex polymer) |
| Pressure relief | Deep contouring, especially for side sleepers | Instant, targeted relief without the sink of memory foam |
| Support | Zoned coils, balanced support | Grid adapts dynamically to pressure points |
| Cooling | Good airflow, optional cooling upgrades | Naturally cool, doesn’t trap heat |
| Motion isolation | Very solid | Good, but slightly more responsive |
| Adjustment period | Minimal | A few nights to weeks |
| Best for | People who want familiar comfort | People who want something completely different |
Comfort and Feel
Helix is all about getting that “just right” feel. The foam layers contour around your body while the coils underneath keep everything supported, so you don’t sink too far. You lie down, and your body just settles without needing to think about it.
Purple feels completely different from the first second. Its Grid doesn’t hug your body the way foam does; it gives under pressure points like your shoulders and hips while staying firm elsewhere. It almost feels like the mattress is adjusting in sections instead of as one surface.
In practice, Helix is easier to like right away. But once the Purple clicks, some people find it hard to go back.
Pressure Relief and Support
Helix handles pressure relief in the traditional way: its foam compresses under the weight of your body (especially around your shoulders and hips), while coils push back to keep your spine aligned. It’s predictable and works well, especially for side sleepers.
Purple approaches pressure relief differently. Its Grid collapses only where pressure is applied, which means your shoulders and hips sink in, but your lower back stays lifted. That creates a more floaty feeling rather than a deep cradle.
The difference shows up most if your pressure points are particularly sensitive. Helix softens them, but Purple more or less removes the pressure entirely.
Temperature and Cooling
Helix does what good hybrid mattresses are supposed to do: its coil system allows airflow, and upgraded models add cooling covers to help manage heat. It’s noticeably better than older, all-foam mattresses, but Purple has the edge here.
Purple’s Grid structure is open and lets air move freely through it. The material doesn’t hold heat the same way foam does, which means the bed stays consistently temperature-neutral without needing extra layers.
Motion Isolation
Helix handles motion better than the average mattress. The foam layers absorb movement well, so if your partner shifts, gets up, or has a completely different sleep schedule, you’re less likely to feel it.
Purple isolates motion decently, but because the Grid is more responsive, you’ll feel a bit more bounce compared to Helix.
If one of you is a light sleeper, Helix is usually the safer choice.
Movement and Responsiveness
Helix leans more toward the classic memory foam feel. This is great for the aforementioned motion isolation, but it also means you feel a bit of resistance when changing positions.
Purple is much more responsive. Its Grid springs back instantly, so you can move around more easily without feeling stuck. For combination sleepers, this tends to matter more than expected.
Ease of Setup and Adjustment
Helix is straightforward. You order it, unbox it, and you’re done. There’s very little time needed to adjust, and most people adapt within a night or two. The 120-night trial also gives you plenty of time to make sure it’s the right fit.
Purple is also easy to set up physically, but it comes with a distinct kind of adjustment period. The feel is unique enough that your body might take a few nights (or longer) to settle into it.
Long-Term Comfort
Helix focuses more on getting the right match up front. Once you find it, the experience stays consistent, and it’s reliable in that you know what you’re getting every night.
Purple feels more dynamic. Because of how its Grid responds to pressure and movement, the experience can feel slightly different depending on how you sleep that night. Some people love that adaptability, while others prefer the predictability of foam.
Materials
Helix uses high-quality foams and individually wrapped coils, which give it a stable, consistent feel. The structure holds up well, especially if you choose the right firmness for your body type.
Purple’s Grid is a different material entirely: a hyper-elastic polymer designed to flex and snap back repeatedly without breaking down the way foam can. In practice, that means it’s less prone to forming body impressions, but it also contributes to the mattress’ very distinct feel.
Who Each Mattress Works Better For
Side Sleepers
Helix is the more reliable pick here. The foam layers compress in a way that cushions your shoulders and hips without much effort on your part. It’s that classic “sink just enough” feeling that side sleepers usually need to avoid pressure buildup.
Purple can work, especially in thicker Grid models, but it’s more dependent on your body weight and sensitivity. The Grid relieves pressure differently, and while some side sleepers love that floaty feeling, others miss the deeper cushioning.
If you don’t want to think too hard about it, Helix is the safer bet.
Back Sleepers
Helix gives you that balanced support that most back sleepers expect. Your hips stay lifted, your spine stays aligned, and everything feels stable. It’s predictable in a way that works for a wide range of body types.
Purple does something interesting here. Its Grid stays firm under your lower back while still relieving pressure elsewhere. That creates a flatter, more “on top of the bed” feel that some back sleepers end up preferring.
If you like a bit of contour, Helix wins. But if you like a more neutral, supported feel, Purple can surprise you.
Stomach Sleepers
Helix tends to win for stomach sleepers, especially with its firmer models. Stomach sleepers need strong support to keep their hips from dipping too far, and Helix’s coil system handles that more traditionally. You get that firmer, stable base that keeps your body aligned.
Purple can work here, but it depends on the model and your body weight. The Grid’s flexibility can sometimes feel a bit too forgiving here if you need firmer support.
Combination Sleepers
Purple has the advantage for combination sleepers. Because its Grid is so responsive, it makes it easier to move around without resistance. You don’t feel like you’re pushing against the mattress when switching positions.
Helix is still good, but you’ll notice a bit more of that foam “drag,” especially if you shift positions frequently during the night.
What I’d Tell a Friend Choosing Between Helix and Purple Mattresses
Helix is refining a system that already works for most people. It’s comfortable, predictable, and easy to live with. Purple is doing something else entirely since it’s not trying to feel like every other mattress. When it works for you, it can feel like an upgrade you didn’t know existed. When it doesn’t, you’ll know pretty quickly.
Here’s the short version.
Go with Helix if:
- You want something that feels good immediately
- You like a traditional mattress feel
- You want a safe, reliable choice for couples
- You don’t want an adjustment period
Go with Purple if:
- You’re open to a completely different feel
- You sleep hot and want better airflow
- You move around a lot at night
- You’ve tried traditional mattresses and felt underwhelmed
If you’re stuck deciding, don’t overthink the features. Ask yourself one question: Do you want your mattress to feel familiar but better, or do you want it to feel different?
That answer will tell you everything you need to know.
