Helix builds pocketed-coil hybrids you pick by sleep position. Purple builds around a buckling-column gel grid. Here is how the two feels differ, where each falls short, and which sleeper each one suits.
These two get compared constantly, and it makes sense: both are online-native brands, both are pitched at people who want something other than a traditional innerspring, and both have loud fan bases. What gets lost in the noise is that they rest on completely different ideas about how a mattress should hold you up. Helix builds pocketed-coil hybrids and sorts you into a specific model based on how you sleep. Purple builds around a flexible polymer grid that buckles under pressure points and stays firm everywhere else. Neither approach is better in the abstract. Here is how they differ, where each falls short, and how to tell which side you land on.
Pick Helix if you want a familiar hybrid feel with pocketed coils, you sleep with a partner and want the bed matched to your body type and sleep position, or you want a firmness you can pick rather than a single feel you have to adapt to. Pick Purple if you run hot, dislike the sinking sensation of memory foam, and want strong pressure relief without a slow-contouring foam layer. If you are a heavier sleeper or a strict side sleeper with shoulder pain, both can work, but the model you choose matters far more than the brand.
| Helix | Purple | |
|---|---|---|
| Construction | Hybrid: foam comfort layers over individually pocketed coils | Buckling-column gel grid over foam, with hybrid versions adding pocketed coils |
| Feel and firmness range | Multiple named models spanning soft to firm; you choose the firmness | A distinctive grid feel with a narrower firmness range across the lineup |
| Best-suited sleeper | Anyone who wants a specific firmness matched to position and body type | Hot sleepers and people who want pressure relief without foam sink |
| Motion isolation | Good; pocketed coils move independently, foam layers absorb the rest | Good on all-foam grid models, slightly livelier on hybrid versions |
| Cooling | Good; coil layer allows airflow, upper-tier models add cooling covers | Excellent; the open grid structure is one of the most breathable surfaces made |
| Edge support | Solid on hybrid models, stronger on the thicker Luxe and Elite tiers | Weaker on all-foam grid models, better on the hybrid versions |
| Typical price tier | Mid-range to premium depending on tier | Mid-range to premium depending on model |
| Trial and warranty | Both brands offer a sleep trial and a multi-year warranty; check current terms at purchase | Both brands offer a sleep trial and a multi-year warranty; check current terms at purchase |

Helix's real advantage is that it does not sell one mattress. The lineup is split into models aimed at different sleep positions and body types, then split again into thickness tiers. A side sleeper who wants pressure relief and a back sleeper who wants a firm, flat surface are not being pushed toward the same bed with a "medium works for everyone" argument.
The construction is a conventional hybrid, a point in its favor if you have slept on innerspring beds your whole life. Individually pocketed coils mean the support layer responds locally rather than as one sheet, so a partner shifting position does not translate across the bed. The coil layer also lets air move through, which matters in a Los Angeles bedroom that stays warm from June into October.
Where it falls short: the model naming takes effort to decode, and picking wrong is expensive to unwind by mail. The entry-level tiers use thinner comfort layers, so a heavier sleeper or a side sleeper with a sharp shoulder can bottom out on them and write off the whole brand as too firm when a thicker tier would have been right. And if you want the deep, slow, cradling sink of high-density memory foam, a hybrid will not give it to you. That feel lives in memory foam mattresses instead.
The grid is not marketing. It is a genuinely unusual piece of engineering: a flexible polymer formed into a hollow column structure that stays rigid under light, distributed load and collapses under concentrated pressure. In practice that means your hips and shoulders sink in while your lower back stays supported, without the delayed rebound you get from memory foam. If you have ever felt trapped in a foam mattress, this is the closest thing to an answer.
Cooling is the other genuine win. Air moves straight through the open grid, and the polymer itself does not soften and trap heat the way viscoelastic foam does. For a hot sleeper, this is the single strongest reason to consider Purple over almost anything else.
Where it falls short: the feel is polarizing in a way that is hard to predict from a description. Some people describe it as floating; others find it oddly firm and squishy at once and never adjust. The all-foam grid models have noticeably softer edges, so if you sit on the side of the bed to put shoes on, look at the hybrid versions instead. The beds are also heavy and awkward to move.
Both can work, but go thicker than you think. Side sleeping concentrates load on the shoulder and hip, so you want enough comfort layer above the support core to let those points drop in. On the Helix side that means a Luxe or Elite tier rather than the base model. On the Purple side the grid handles this well by design, since it collapses exactly where pressure concentrates. Our guide to the best mattress for side sleepers covers what to check for.
Purple has the edge here, and it is not close on the all-foam grid models. Helix hybrids are still cooler than an all-foam bed because of the coil layer, and the upper tiers add cooling covers, but the open grid is a different category of breathable. See our hot sleeper guide for the other factors that matter here.
Helix's model-matching is genuinely useful for couples, because you can pick a firmness that splits the difference rather than one person surrendering. Motion isolation is good on both. The tiebreaker is usually edge support: if two people spread out, a hybrid with reinforced edges gives you more usable surface than a soft-edged all-foam bed. Our note on why edge support matters explains what to press on when you test.
Neither brand is a treatment, and be skeptical of any mattress marketed as one. What helps is a surface that keeps your spine roughly in the alignment it holds when you stand. For most back-pain sleepers that means medium-firm support with enough give at the hips. Both brands can hit that; the specific model matters more than the logo.
Compare like tiers, not brand to brand. An entry-level bed from either company is a different product from that company's premium tier, so comparing a base Helix to a premium Purple tells you nothing useful. Also weigh what a bed costs to keep: one that holds its support for eight years is cheaper than two that sag in four. Our guide on how long mattresses last gets into that math.
We stock Helix in our showrooms, which is the part most comparison articles cannot offer you. Helix is an online-native brand, so the usual advice is to order one, sleep on it, and mail it back if it is wrong. You can skip that entirely: come lie on the Midnight, the Twilight, and the Luxe and Elite tiers back to back and find out in twenty minutes what a trial period would take you three weeks to learn. We also carry Brooklyn Bedding and Birch, two more bed-in-a-box brands you can test in person rather than guess at.
We do not carry Purple. If the grid feel is specifically what you are after, buy it from Purple. But if what you actually want is pressure relief without the sinking, cool sleep, and a responsive surface, that description also fits a well-chosen hybrid, and you can confirm it with your own body instead of a return window. For deep contouring at the premium end, Tempur-Pedic and Stearns & Foster are the beds to lie on. Every mattress we sell comes with our free 120-night comfort guarantee, so a decision made in the store is not one you are stuck with.
Neither is better outright; they solve different problems. Helix gives you a conventional hybrid feel with a firmness you select, which suits people who know roughly what they like. Purple gives you a grid surface that relieves pressure without the sink of memory foam and sleeps unusually cool, which suits hot sleepers and people who dislike foam. The right answer depends on which of those descriptions sounds like your problem.
Yes, in select retail showrooms, including all five of ours in Los Angeles. Helix started as a direct-to-consumer brand, so many people assume online is the only option, but you can lie on the Midnight, Twilight, and the Luxe and Elite tiers in person before you commit.
If you are in the Los Angeles area, any of our showrooms carries the Helix lineup on the floor. Spend at least ten minutes on a bed in your normal sleeping position rather than sitting on the edge for thirty seconds. Our guide on how to test a mattress in store covers what to actually pay attention to.
For the right sleeper, yes. The grid is a real innovation and the cooling performance is among the best available. The catch is that the feel is polarizing and hard to predict from reading about it, and edge support on the all-foam models is soft. If you can, lie on one before deciding rather than relying on reviews.
Purple, like most quality mattresses, is generally expected to last somewhere in the range of seven to ten years with proper support underneath, though how long any mattress lasts depends heavily on body weight, base type, and how well it is maintained. The polymer grid itself is durable; the foam layers beneath it are usually what softens first. Using a proper foundation and rotating the mattress as the manufacturer directs helps either brand reach the top of its range.
Purple, on the strength of the open grid. Air passes straight through the columns instead of being trapped in foam. Helix hybrids are still much cooler than an all-foam mattress thanks to the coil layer, and the higher tiers add cooling covers, so if you want a hybrid feel and run warm, a Helix Luxe or Elite is a reasonable middle ground.
Comparison articles, ours included, can only get you so far. Bodies disagree with descriptions all the time. Take our sleep quiz for a starting point matched to how you actually sleep, or come test the hybrid mattresses we stock in person at any of our five LA showrooms and settle it in an afternoon.
