How the five categories compare
| Category | Helix Midnight | Purple Mattress | Gap |
|---|---|---|---|
| Support | 84 | 80 | 4 |
| Cooling widest gap | 80 | 96 | 16 |
| Motion isolation | 82 | 76 | 6 |

How the scoring works. All five categories count equally, at ×3 each, and the winner is whichever bed has the higher weighted total. The category marked widest gap is where these two differ most, at 16 points - it is the clearest explanation of the result, not the thing that produced it. Scores run 0 to 100 and come from our review scorecards.
Category by category, in detail
Cooling — Purple Mattress, the widest gap between them
Purple Mattress takes cooling at 96 against 80, a clear gap of 16 points. Cooling governs whether you wake up warm at three in the morning, which puts this column in front of hot sleepers above all, and couples second.
That comes straight off the build. Purple Mattress uses a GelFlex Grid, backed by soft flex knit cover.
In practice, a 16-point gap here is the strongest single argument for Purple Mattress on this page, and it is most of what you are paying the extra $200 for.
Support — Helix Midnight
Here Helix Midnight leads 84 to 80, negligible at 4 points. Because support governs whether the spine stays in line once your hips and shoulders sink in, the gap lands hardest on anyone who sleeps on their back or front, and heavier bodies most of all.
You can see why in the layers. Helix Midnight uses a pocketed coil support core, up to 1,000 individually wrapped coils, with firmer coils along the perimeter, backed by responsive transition foam and DuraDense foam base.
Motion isolation — Helix Midnight
Motion isolation goes to Helix Midnight, 82 against 76 - a modest 6-point gap. What it decides is whether someone else getting up wakes you, and the people it decides it for are couples, dog owners, and anyone who wakes at the smallest thing.
That follows from what is inside. Helix Midnight uses a pocketed coil support core, up to 1,000 individually wrapped coils, with firmer coils along the perimeter, backed by Memory-Plus foam comfort layer and responsive transition foam.
Edge support — Helix Midnight
Edge support goes to Helix Midnight, 80 against 72 - a modest 8-point gap. What it decides is whether the sides hold firm or roll away under you, and the people it decides it for are couples using the full width of a queen, anyone who sits on the edge to dress, and heavier sleepers.
That is a construction difference. Helix Midnight uses a pocketed coil support core, up to 1,000 individually wrapped coils, with firmer coils along the perimeter.
Value — Helix Midnight
Value goes to Helix Midnight, 86 against 78 - a modest 8-point gap. What it decides is how much bed the price actually buys, and the people it decides it for are anyone cross-shopping on price instead of on a single feature.
That tracks the price directly: $999 for a queen Helix Midnight against $1,199 for Purple Mattress, 20% more. Value scores what you get back per dollar, not how good the bed is outright, so a cheaper bed can win this column and still lose the matchup.
Construction and materials
Helix Midnight is an entry-level Core Collection pocketed-coil hybrid at 11.5 or 12 inches tall, built from 5 layers. Purple Mattress is an all-foam bed with a hyper-elastic polymer grid on top at 9.25 or 9.5 inches, built from 5.
That is the root difference between them, and most of the scorecard follows from it. A hybrid and a memory foam bed do not fail in the same places: with Helix Midnight, foam sits on top of a coil core, so it splits the difference - contour at the surface, airflow and edge strength underneath. With Purple Mattress, every layer is foam, so movement dies where it starts, but there is no coil unit to move air or stiffen the perimeter.
Helix Midnight has a coil unit - up to 1,000 individually wrapped coils in a roughly 8-inch layer, firmer along the perimeter - and Purple Mattress has none, which is the cleanest single explanation for the bounce, airflow and edge differences between them.
Both carry CertiPUR-US. Helix Midnight additionally carries Greenguard Gold.
Helix Midnight is Assembled in the Helix Arizona factory. Purple Mattress does not publish where it is made.

Firmness and feel, by sleeper
Helix Midnight is published at 6.0 out of 10 and Purple Mattress at 6.0. That is 0.0 of a point apart, which is less than the difference body weight alone makes, so neither will feel categorically softer to everyone.
Side sleepers: both land in the usual window, Helix Midnight for average and heavy builds and Purple Mattress for average and heavy. Support scores are close too, so this position is not where the decision gets made.
Back sleepers: both land in the usual window, Helix Midnight for light, average and heavy builds and Purple Mattress for light, average and heavy. Support scores are close too, so this position is not where the decision gets made.
Stomach sleepers: both land in the usual window, Helix Midnight for light and average builds and Purple Mattress for light and average. Support scores are close too, so this position is not where the decision gets made.
| Position | Body weight | Usual window | Helix Midnight (6.0) | Purple Mattress (6.0) |
|---|---|---|---|---|
| Side | Light | 3.0-5.5 | Too firm | Too firm |
| Side | Average | 4.0-6.5 | In range | In range |

Where each one wins and loses
Helix Midnight
- Motion isolation, 82 against 76. The pocketed coil support core is the reason: up to 1,000 individually wrapped coils, with firmer coils along the perimeter.
- Edge support, 80 against 72. The pocketed coil support core is the reason: up to 1,000 individually wrapped coils, with firmer coils along the perimeter.
- Value, 86 against 78. A 8-point lead on a 100-point scale.
- Cheaper by $200 on a queen. $999 against $1,199, 17% less for the same size.
- Also certified Greenguard Gold. Certification the other bed does not publish.
- Cooling, 80 against 96. Purple Mattress leads by 16 points here, which is the gap you would be accepting.
Purple Mattress
- Cooling, 96 against 80. The GelFlex Grid is the reason: a hyper-elastic polymer moulded into a grid of buckling columns with well over 1,400 air channels, which collapses under pressure points and springs back instantly.
- Motion isolation, 76 against 82. Helix Midnight leads by 6 points here, which is the gap you would be accepting.
- Edge support, 72 against 80. Helix Midnight leads by 8 points here, which is the gap you would be accepting.
- Value, 78 against 86. Helix Midnight leads by 8 points here, which is the gap you would be accepting.
- Dearer by $200 on a queen. $1,199 against $999, which the scorecard has to justify.
Who should pick which

FAQ
Which is better overall, the Helix Midnight or the Purple Mattress?
Helix Midnight wins on points by 2 points, scoring every category at equal weight. The clearest difference between them is cooling, where it scores 80 against 96 - the widest gap on the card, and the best short explanation of the result rather than the thing that produced it.
That does not make it the better bed for everyone. If your priority happens to be a category Purple Mattress leads, the honest answer flips, which is why the full scorecard is published above and not just the verdict.
Is the Purple Mattress worth $200 more than the Helix Midnight?
A queen Purple Mattress is $1,199 against $999, 20% more. It earns some of that back: it leads on cooling. Helix Midnight scores 86 on value against 78, and that column exists precisely to answer this question.
Which is firmer, the Helix Midnight or the Purple Mattress?
Helix Midnight is published at 6.0 out of 10, Purple Mattress at 6.0. That is close enough that your body weight will change the felt firmness more than the difference between the two beds does - a heavier sleeper compresses both further and will read both as softer than a lighter sleeper does.
Both ship in a single firmness, so what you read is what arrives.
Which has the better trial and return policy?
Helix Midnight gives 100 nights, Purple Mattress gives 100. The trials are identical. Neither publishes a return fee on its specification, so confirm that with the retailer before you buy - it is the one cost that only appears when things go wrong.
What is the real difference between a hybrid and a memory foam here?
Helix Midnight is an entry-level Core Collection pocketed-coil hybrid at 11.5 or 12 inches. Purple Mattress is an all-foam bed with a hyper-elastic polymer grid on top at 9.25 or 9.5. With helix midnight, foam sits on top of a coil core, so it splits the difference - contour at the surface, airflow and edge strength underneath.
with purple mattress, every layer is foam, so movement dies where it starts, but there is no coil unit to move air or stiffen the perimeter. That is what the scorecard above is measuring when it separates them by 2 points.
Does the cooling difference actually matter day to day?
It is a 16-point gap on a 100-point scale, 80 against 96, the widest on the card. Cooling governs whether you wake up warm at three in the morning, and the people who feel it are hot sleepers above all, and couples second. If none of that describes you, this is the wrong page to decide on: the two beds are closer everywhere else, and you should weight whichever column does describe you.
The scorecard is published in full for that reason, and no category is weighted above another.
