Our Verdict
Both Purple and Helix make great mattresses, but they each take a unique approach. Helix creates more typical hybrid mattresses, whereas Purple’s use of their patented gel grid creates a more unique feel.
In our tests, both Helix and Purple had some good scores, some okay scores, and some great scores, depending on the model. On average, Helix mattresses scored better and were also less expensive compared to Purple.
In our view, the Helix mattress line is a far better value than Purple mattresses.
That said, the Purple gel grid is a unique material that is not emulated by any Helix model. If you’ve laid on the Purple grid and simply love that feel then there really is no other choice than Purple.
However, for most people, the huge range of firmnesses and affordability of Helix makes it the clear choice over Purple.

Which Mattresses Are We Comparing?
Helix offers a mix of hybrids in varying firmnesses and with varying comfort materials and covers. Most all of their mattresses come in three varieties—Standard, Luxe, and Elite.
For this comparison, we’ll be looking at the:
- Helix Midnight (budget-friendly)
- Helix Midnight Luxe (great value)
- Helix Midnight Elite (luxury pick)
The Midnight collection is a well-rounded mattress that is suitable for a wide range of sleepers in any sleeping position.
Purple manufactures a mix of foam and hybrid options, all of which include their patented Purple gel pad. In this comparison, we’ll be looking at the following models:
- Purple Original (foam + Purple gel pad)
- Purple Restore Plus (hybrid + Purple gel pad)
- Purple Restore Premier (hybrid + Purple gel pad)
The Purple Original is a foam + Purple gel pad mattress and the Restore mattresses are both hybrids.
Lower-scoring mattresses including the Purple Plus, Purple Restore, and Purple Newday were excluded based on their lower overall performance scores.
So with that context in mind, let’s get started.
Cooling Test
Both Helix and Purple had identical average cooling performance scores—an average of 9.00 out of 10. Both brands had limited heat retention and great breathability.
Cooling Test | Score | Baseline | Max Temp | Ending Temp |
---|---|---|---|---|
Helix Midnight | 9.0 | 83.6° | 90.7° | 85.5° |
Helix Midnight Elite | 10 | 80.1° | 91.3° | 84.0° |
Helix Midnight Luxe | 9.0 | 83.8° | 91.0° | 86.6° |
Purple | 10 | 79.7° | 89.2° | 84.0° |
Purple Restore Plus | 9.0 | 81.7° | 91.7° | 84.7° |
Purple Restore Premier | 9.0 | 83.0° | 91.3° | 86.2° |
- Baseline Temperature – the temperature of the mattress before anyone lies on it
- Maximum Temperature (0 minute) – the temperature of the mattress after lying on it for 15 minutes
- Ending Temperature (after 5 minutes) – the temperature of the mattress after being lied upon and having no one on it for 5 minutes
One mattress from each brand earned a perfect 10 out of 10 score—the Helix Midnight Elite and the Purple Original.
Below, you can watch a video of how the heat dissipates on each mattress during our cooling test. For this test, we lie on the mattress for 15 minutes, get off the mattress, and then take periodic surface-level temperature measurements.

Sinkage Test
On average, Helix had deeper sinkage than Purple. Helix mattresses had a range of Minimal to Very Deep sinkage, with an average sinkage of 2.25″. Purple sinkage was more restrictive—Minimal to Moderate sinkage, with an average sinkage of 2.03″.
For reference, the average level of sinkage across all mattresses tested to date is 2.18″.
Sinkage Test | Sinkage Feel | Sinkage Depth |
---|---|---|
Helix Midnight | Minimal | 1.98″ |
Helix Midnight Elite | Very Deep | 2.64″ |
Helix Midnight Luxe | Moderate | 2.15″ |
Purple | Moderate | 2.24″ |
Purple Restore Plus | Minimal | 1.99″ |
Purple Restore Premier | Minimal | 1.82″ |
For the deepest sinkage, opt for the Helix Midnight Elite (2.64″), or for minimal sinkage, the Purple Restore Premier (1.82″) is a great pick.
The level of sinkage for each mattress is documented in the images below.

Deeper sinkage can be beneficial for side sleepers or those looking for a bit more contour and dramatic hug.
Motion Transfer Test
Motion transfer levels are lower on Helix mattresses compared to Purple mattresses. The average motion transfer level on Helix is 7.16 m/s² and the Purple average is 8.62 m/s².
Across all mattresses we’ve tested to date, the average motion transfer is 8.50 m/s². Anything below 5.00 m/s² could be considered low motion, but that doesn’t mean that a lower number wouldn’t be better.
Motion Transfer Test | Score | Acc. Range |
---|---|---|
Helix Midnight | 9.0 | 7.25 m/s² |
Helix Midnight Elite | 7.7 | 10.21 m/s² |
Helix Midnight Luxe | 10 | 4.03 m/s² |
Purple | 10 | 2.23 m/s² |
Purple Restore Plus | 7.2 | 11.27 m/s² |
Purple Restore Premier | 6.7 | 12.36 m/s² |
That being said, the Purple Original had the lowest levels of motion transfer among all mattresses in this comparison (2.23 m/s²) with the Helix Midnight Luxe close behind at 4.03 m/s².
The mattress with the highest motion transfer is the Purple Restore Premier at 12.36 m/s².
The level of motion transfer on the Helix vs. Purple mattresses is shown in the videos below.

Response Test
Regarding response time, Purple mattresses are the only mattresses with perfect 10 out of 10s. The majority of these mattresses are mostly recovered by 0.2 seconds and fully recovered by 0.3 seconds—incredibly fast.
Response Test | Score | Mostly Recovered | Completely Recovered |
---|---|---|---|
Helix Midnight | 5.7 | 1.0 seconds | 1.2 seconds |
Helix Midnight Elite | 9.0 | 0.3 seconds | 1.0 seconds |
Helix Midnight Luxe | 9.5 | 0.3 seconds | 0.4 seconds |
Purple | 10 | 0.2 seconds | 0.3 seconds |
Purple Restore Plus | 10 | 0.2 seconds | 0.3 seconds |
Purple Restore Premier | 10 | 0.2 seconds | 0.3 seconds |
The Helix Midnight, Helix Midnight Luxe, and Helix Midnight Elite had response scores below 10, with the Midnight being the worst at a 5.7.
On average, we see a mostly recovered response time of 0.4 seconds and a fully recovered time of 0.8 seconds.
All Purple mattresses in this comparison are significantly better than the average (as well as the Helix Midnight Luxe).
A closer visual of the level of responsiveness for each mattress is documented in the videos below.

Bounce Test
Talking through bounce, it’s important to mention that bounce is largely preferential. Some sleepers will enjoy higher levels of bounce while others are looking for more subdued bounce. There is no right or wrong answer here.
Bounce Test | Bounce Feel | Bounce Height |
---|---|---|
Helix Midnight | High | 10.19″ |
Helix Midnight Elite | Moderate | 8.08″ |
Helix Midnight Luxe | Low | 7.47″ |
Purple | Very High | 12.79″ |
Purple Restore Plus | Very High | 12.20″ |
Purple Restore Premier | Moderate | 9.46″ |
Comparing Helix to Purple, Purple has a wider range of bounce (3.33″) compared to Helix’s range of bounce (2.72″).
The videos below illustrate bounce levels via a ball bouncing on the mattress.

The average level of bounce across all mattresses tested to date is 9.61″.
The Helix Midnight Luxe has the lowest level of bounce at 7.47″ with the Helix Midnight Elite close behind at 8.08″. Both of these mattresses have less bounce than average.
The Purple Restore Premier (9.46″) and Helix Midnight (10.19″) are just slightly more bounce than average.
And the Purple Original (12.79″) and Purple Restore Plus (12.20″) have significantly higher levels of bounce than average.
Edge Support Test
Between Helix and Purple, Helix had better edge support on average.
Helix’s average edge support sinkage was 4.0″, while Purple’s average sinkage came in at 5.17″. This is compared to the average edge support sinkage on all mattresses we’ve tested to date, which is 4.10″.
When it comes to edge support, being average isn’t where you want to be. 4.0″ or less is what I would call great edge support. Much worse than that and it starts to feel less than great when it comes to both support and comfort.
Check out the table below for a full rundown of edge support on the complete collection:
Edge Support Test | Score | Sitting Sinkage | Lying Support |
---|---|---|---|
Helix Midnight | 7.8 | 5.00″ | Good |
Helix Midnight Elite | 9.5 | 3.00″ | Excellent |
Helix Midnight Luxe | 8.9 | 4.00″ | Excellent |
Purple | 5.1 | 7.75″ | Mediocre |
Purple Restore Plus | 10 | 2.75″ | Outstanding |
Purple Restore Premier | 9.9 | 3.25″ | Outstanding |
The best performers here are the Helix Midnight Elite, Purple Restore Plus and the Purple Restore Premier. All three of these mattresses have less edge sinkage than average.
Check out the images below for a visual of edge support when seated on each mattress.

Sex Test
This part of our scoring looks at the expected sex performance based on several performance factors.
The best mattresses for sex have high bounce, good edge support, quiet materials, and good pressure relief and cooling.
These 5 factors make up the NapLab sex performance score and from these factors, we can generate a sex score for each mattress.
The table below shows how sex performance varies between these two brands, with Purple outperforming Helix and being the better mattress choice for sex.
Sex Test | Sex Score | Bounce | Edge Support | Noise | Pressure Relief | Cooling |
---|---|---|---|---|---|---|
Helix Midnight | 8.6 | 8.9 | 7.5 | 8.0 | 9.0 | 9.0 |
Helix Midnight Elite | 8.4 | 7.5 | 10 | 10 | 10 | 10 |
Helix Midnight Luxe | 7.7 | 7.1 | 8.8 | 8.0 | 10 | 9.0 |
Purple | 8.8 | 10 | 4.1 | 10 | 9.0 | 10 |
Purple Restore Plus | 9.9 | 10 | 10 | 10 | 9.0 | 9.0 |
Purple Restore Premier | 8.8 | 8.4 | 9.7 | 10 | 9.0 | 9.0 |
Helix has a sex average of 8.55 and Purple has an average of 9.21 out of 10.
Helix is not a bad performer, but certain mattresses do lose points for lower bounce levels and lacking edge support.
The only mattress in this comparison to nearly earn a perfect sex score is the Purple Restore Plus with a 9.9 out of 10.
Pressure Relief Test
Pressure relief is good on all of these mattresses in this comparison, with consistent scores between 9.0 – 10 out of 10. That being said, the average pressure relief for Helix mattresses is better (9.09) than the average on Purple mattresses (8.33).
Pressure Relief Test | Score | Comfort Layer | Support Layer |
---|---|---|---|
Helix Midnight | 9.0 | 3.0″ | 9.0″ |
Helix Midnight Elite | 10 | 6.0″ | 10.0″ |
Helix Midnight Luxe | 10 | 5.0″ | 9.0″ |
Purple | 9.0 | 5.5″ | 4.0″ |
Purple Restore Plus | 9.0 | 5.0″ | 8.0″ |
Purple Restore Premier | 9.0 | 3.0″ | 10.0″ |
When thinking about the overall pressure relief of a mattress, we mainly consider the thickness of the comfort layer compared to the total thickness of the mattress.

Generally, we want to see at least 3.0″ of comfort material and at least 9-10″ of mattress thickness (for adults). Mattresses with a thicker comfort layer (like the Purple Original) can sometimes get away with a thinner total thickness without it significantly negatively affecting pressure relief.
But for fantastic pressure relief, you will usually need to opt for thicker options like the Helix Midnight Luxe or Helix Midnight Elite, both of which scored a perfect 10 out of 10.

The amount of comfort material and total mattress thickness are two of the most important factors when considering pressure relief.
Off-Gassing Test
Off-gassing is less strong with the Helix Midnight and Helix Midnight Luxe than it was on the Helix Midnight Elite as well as all Purple mattresses.
Off-Gassing Test | Score | Initial Smell | Smell Duration |
---|---|---|---|
Helix Midnight | 9.4 | Moderate | 2 days |
Helix Midnight Elite | 8.3 | Strong | 6 days |
Helix Midnight Luxe | 9.2 | Moderate | 3 days |
Purple | 8.9 | Strong | 4 days |
Purple Restore Plus | 7.2 | Strong | 10 days |
Purple Restore Premier | 2.8 | Strong | 26 days |
All Helix mattresses in this comparison off-gas between 3-6 days. Purple mattresses range from 4-26 days to fully dissipate any odors.
For reference, the average off-gassing period is 5 days. If you’re sensitive to strong odors, this could be an issue for you.
Company
When it comes to company policy, Helix standard mattresses and all Purple mattresses are similar. They both have the same length of trial and a 10-year warranty.
Shipping and returns are both free as well and both brands manufacture mattresses from within the US.
Company | Helix | Purple |

Use the table below to better determine the firmness range that may be best suited for you, based on your personal weight and preferred sleeping position.

Support & Sleeping Positions
Depending on your sleeping position, body weight, and other personal preferences, you may find any of the mattresses above to be best for you.
Check the following sleeper profile charts below. This table would be accurate for any sleeper looking primarily at the 6 main mattresses we’re highlighting in this comparison.
Sleeper Weight | Stomach Sleepers | Side Sleepers | Back Sleepers |
---|---|---|---|
Under 150 lbs. | Yes | Yes | Yes |
150-250 lbs. | Yes | Yes | Yes |
250-300 lbs. | Yes | Yes | Yes |
People who may not like this firmness include:
- Lightweight side sleepers: If you are a lightweight side sleeper the Purple Original is likely the best option from Purple. The Helix Moonlight or Helix Sunset are also very supportive and comfortable. To a lighter sleeper, the slightly softer feel allows for easier contour that better supports your body on its side.
- Heavy weight back or stomach sleepers: If you are a heavier-weighted back or stomach sleeper the best models are going to be the Purple Restore, Purple Restore Plus, Helix Twilight or Helix Dawn. These have a medium to firm feel, which has the best chance of creating the ideal support dynamic.
- Plus sleepers: Plus-sized sleepers would be best with the Helix Plus.
Design
Both Helix and Purple offer a mix of hybrids, although Purple is the only brand to include the Purple gel pad.
That being said, the Purple gel pad doesn’t always necessarily mean better performance. The average Purple overall score is 9.38, lower than Helix’s average overall score of 9.53.
