Our Verdict
When considering Helix vs. Saatva, both offer a wide selection of high-quality mattresses. In addition, both also have a wide range of firmnesses from 3.5 (soft) up to 8 (firm).
Helix mattresses are hybrids (foam + coil) and Saatva mattresses offer an all-coil or hybrid configuration. There are also differences in the feel. Loom & Leaf has the classic memory foam feel, Helix is a bit more balanced, and Saatva offers a more traditional feel.

Among these six models, here are the categories where each mattress excelled.
The Helix Midnight Luxe had the lowest motion transfer and tied for the best pressure relief.
The Helix Plus had the least sinkage, fastest response time, and tied for best edge support. It’s also the best for sleepers over 300 pounds.
The Loom & Leaf mattress had the least amount of bounce, most sinkage, and tied for the least off-gassing.
The Saatva Classic scored the best overall, as well as had the best cooling, most bounce, tied for best edge support, tied for best pressure relief, tied for the least amount of off-gassing, and Saatva also had the best company score.
The Saatva Memory Foam Hybrid scored the best for cooling as well as being tied for the least amount of off-gassing, and Saatva also had the best company score.
Cooling Test
The cooling performances of these mattresses were all pretty good, with the Saatva Classic having the top score.
Cooling Test | Score | Baseline | Max Temp | Ending Temp |
---|---|---|---|---|
Helix Midnight | 9.0 | 83.6° | 90.7° | 85.5° |
Helix Midnight Luxe | 9.0 | 83.8° | 91.0° | 86.6° |
Helix Plus | 9.0 | 86.2° | 91.8° | 85.5° |
Saatva Classic | 10 | 81.4° | 94.0° | 90.1° |
Saatva Memory Foam Hybrid | 10 | 78.0° | 89.4° | 81.3° |
Loom & Leaf | 9.0 | 79.1° | 87.6° | 80.8° |
- 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
All of these mattresses did a good job of dissipating heat, preventing build-up, and feeling comfortable when lying on the mattress during our tests.
The top-performing mattress was the Saatva Classic, which makes sense in that this mattress is a coil-on-coil mattress, having more room for airflow than any other mattress we tested in this review.
Videos below show exactly how the heat dissipates off of the mattress during our tests.

Sinkage Test
The sinkage levels vary pretty widely between Helix and Saatva. Helix ranges between very minimal to moderate. Saatva ranges from moderate to extremely deep.
Sinkage Test | Sinkage Feel | Sinkage Depth |
---|---|---|
Helix Midnight | Minimal | 1.98″ |
Helix Midnight Luxe | Moderate | 2.15″ |
Helix Plus | Very Minimal | 1.50″ |
Saatva Classic | Deep | 2.40″ |
Saatva Memory Foam Hybrid | Minimal | 1.88″ |
Loom & Leaf | Extremely Deep | 3.09″ |
The average level of sinkage across all mattresses tested to date is 2.2″.
Based on these numbers, all of the mattresses tested here are less than average except for the Saatva Classic and Loom & Leaf.
Images below show the level of sinkage for each mattress.

Motion Transfer
Motion transfer was best on the Helix Midnight Luxe and Loom & Leaf, but still good on all of these models.
Motion Transfer Test | Score | Acc. Range |
---|---|---|
Helix Midnight | 9.0 | 7.25 m/s² |
Helix Midnight Luxe | 10 | 4.03 m/s² |
Helix Plus | 9.4 | 6.31 m/s² |
Saatva Classic | 9.6 | 5.86 m/s² |
Saatva Memory Foam Hybrid | 7.7 | 10.11 m/s² |
Loom & Leaf | 10 | 5.02 m/s² |
The average amount of motion transfer is 5.83 m/s² (based on all of our tests to date).
As you can see, the Saatva Classic falls about at the average and the Helix Plus is just slightly beyond the average.
The Helix Midnight had quite a bit more motion transfer than average and the Saatva Memory Foam Hybrid has the most motion transfer of all.
The level of motion transfer is documented in the video below. The graphs that follow each video show a quantifiable version of motion transfer based on accelerometer data.
Helix Midnight Motion Transfer Test

The Helix Midnight had the highest level of motion transfer, as you can see in the graphic above. Motion translated across the mattress well past 1 full second.
Helix Midnight Luxe Motion Transfer Test

The Helix Midnight Luxe had great motion transfer, about 1/2 the amount of motion from the initial drop compared to the Helix Midnight, and that energy dissipated quicker as well.
Helix Plus Motion Transfer Test

The Helix Plus mattress had slightly more motion transfer than average with a relatively fast energy absorption rate.
Loom & Leaf Motion Transfer Test

The Loom & Leaf is the only mattress in this comparison that is coil-free. The energy from the initial ball drop is absorbed very quickly into the mattress. As you can see, basically all of the energy is gone before even a full second has elapsed.
Saatva Classic Motion Transfer Test

The Saatva Classic is the only mattress in this comparison with a coil-on-coil system. This obviously generates a lot more bounce initially, but I will say that the bounce dissipates fairly quickly and the overall motion transfer level was about average (compared to all other mattresses we’ve tested to date).
Saatva Memory Foam Hybrid Motion Transfer Test

The Saatva Memory Foam Hybrid Foam mattress has the most motion transfer of all the mattresses in this comparison. You can see the high energy levels from the initial ball drop and then the mattress struggles to control this motion for well over 1 full second.
Response Test
The response time is excellent for most of these mattresses, excluding the Helix Midnight, which both have top layers of memory foam and are a bit slower because of it.
Response Test | Score | Mostly Recovered | Completely Recovered |
---|---|---|---|
Helix Midnight | 5.7 | 1.0 seconds | 1.2 seconds |
Helix Midnight Luxe | 9.5 | 0.3 seconds | 0.4 seconds |
Helix Plus | 10 | 0.2 seconds | 0.3 seconds |
Saatva Classic | 8.7 | 0.4 seconds | 0.8 seconds |
Saatva Memory Foam Hybrid | 9.0 | 0.3 seconds | 1.0 seconds |
Loom & Leaf | 7.1 | 0.6 seconds | 1.6 seconds |
The average response time across all mattresses that we’ve tested to date is 0.56 seconds to be mostly recovered and 0.94 seconds to be fully recovered.
The Helix Midnight Luxe, Helix Plus, Saatva Classic, and Saatva Memory Foam Hybrid all have faster response times than average.
You can see these material responses in real-time in the video below.
Helix Midnight Response Test
Helix Midnight Luxe Response Test
Helix Plus Response Test
The Helix Midnight and Loom & Leaf both have thicker memory foam layers towards the top of the mattress. This definitely slows response time and provides a deeper hug and contour when lying on the mattress.

Bounce Test
The level of bounce varies greatly between these six mattresses, as you can see in the table below.
Bounce Test | Bounce Feel | Bounce Height |
---|---|---|
Helix Midnight | High | 10.19″ |
Helix Midnight Luxe | Low | 7.47″ |
Helix Plus | Moderate | 9.38″ |
Saatva Classic | Extremely High | 14.67″ |
Saatva Memory Foam Hybrid | Extremely High | 14.06″ |
Loom & Leaf | Very Low | 4.72″ |
The mattresses with memory foam have the lowest levels of bounce—Loom & Leaf and Helix Midnight Luxe. The Loom & Leaf has the lowest at 4.72″ and the Helix Midnight Luxe has the second-lowest, at 7.47″.
For comparison, the average amount of bounce across all mattresses tested to date is 9.35″.
The Helix Plus has slightly more bounce than average, 9.38″.
The Helix Midnight, Saatva Memory Foam Hybrid, and Saatva Classic all have progressively more bounce than the preceding mattress. Ranging from 9.38 to 14.67″.
Bounce levels can also be viewed in real-time via the short video clips below.

Edge Support Test
Concerning edge support, there are definitely some of these mattresses that stand out from the others.
Edge Support Test | Score | Sitting Sinkage | Lying Support |
---|---|---|---|
Helix Midnight | 7.8 | 5.00″ | Good |
Helix Midnight Luxe | 8.9 | 4.00″ | Excellent |
Helix Plus | 10 | 3.00″ | Outstanding |
Saatva Classic | 10 | 3.00″ | Outstanding |
Saatva Memory Foam Hybrid | 9.7 | 3.50″ | Outstanding |
Loom & Leaf | 7.5 | 6.25″ | Excellent |
The average level of sinkage (when sitting right at the edge of the mattress) is 4.67″ (based on all of our mattress tests to date).
The Helix Midnight Luxe, Helix Plus, Saatva Classic, and Saatva Memory Foam Hybrid all have less edge sinkage than average.

Sex Test
Our sex rating formula looks at 5 different factors weighted based on their importance.

All factors are not equal in terms of significance, but each plays an important role.
Through our tests, we subjectively assigned the following percentages to each category within the overall sex score:
- Bounce: 60%
- Edge Support: 20%
- Noise: 10%
- Pressure Relief: 5%
- Cooling: 5%
Using this method, we generated the following scores below:
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 Luxe | 7.7 | 7.1 | 8.8 | 8.0 | 10 | 9.0 |
Helix Plus | 8.6 | 8.3 | 10 | 6.0 | 9.0 | 9.0 |
Saatva Classic | 9.9 | 10 | 10 | 8.0 | 10 | 10 |
Saatva Memory Foam Hybrid | 9.7 | 10 | 9.4 | 8.0 | 9.0 | 10 |
Loom & Leaf | 6.1 | 5.4 | 5.9 | 10 | 10 | 9.0 |
The sex performance of all of these mattresses is fantastic for all models excluding the Helix Midnight Luxe (7.7) and the Loom & Leaf (6.1).
Being that these two mattresses include a rather thick top layer of memory foam, the poorer sex performance makes sense, as memory foams have less bounce than a poly foam and certainly less than coils.

The top-scoring mattress for sex performance is the Saatva Classic (9.9), closely followed by the Saatva Memory Foam Hybrid (9.7). Both of these mattresses have excellent bounce paired with fantastic edge support.
The Helix Plus (8.6) and Helix Midnight (8.6) scored well in this category as well and are good options for well-balanced, high-performing mattresses for sex.
Pressure Relief Test
Pressure relief on all of these mattresses was quite good. Good pressure relief on a mattress oftentimes comes from a thicker comfort layer and sufficiently thick support layer.
Pressure Relief Test | Score | Comfort Layer | Support Layer |
---|---|---|---|
Helix Midnight | 9.0 | 3.0″ | 9.0″ |
Helix Midnight Luxe | 10 | 5.0″ | 9.0″ |
Helix Plus | 9.0 | 5.0″ | 8.0″ |
Saatva Classic | 10 | 4.5″ | 7.0″ |
Saatva Memory Foam Hybrid | 9.0 | 2.5″ | 9.0″ |
Loom & Leaf | 10 | 4.5″ | 7.5″ |
Looking at the six mattresses in this comparison, we see the best scores from the Helix Midnight Luxe, Loom & Leaf, and the Saatva Classic. All of these mattresses have between a 4.5-5″ thick comfort layer with a plush cover.

The Helix Midnight, Helix Plus, and Saatva Memory Foam Hybrid are just slightly behind the others with a score of 9.0 out of 10.
The Helix Midnight has a comfort layer of only 3.0″ and a thinner cover, compared to the others.
Off-Gassing Test
Moving right along, let’s talk about off-gassing. The performance here was very good and a little faster than average.
On average, most mattresses take around 2.8 days to off-gas. Every mattress that we tested here was faster than that with one exception being the Helix Midnight Luxe, which took about 3 full days to fully off-gas.
Off-Gassing Test | Score | Initial Smell | Smell Duration |
---|---|---|---|
Helix Midnight | 9.4 | Moderate | 2 days |
Helix Midnight Luxe | 9.2 | Moderate | 3 days |
Helix Plus | 9.4 | Moderate | 2 days |
Saatva Classic | 10 | None | 0 days |
Saatva Memory Foam Hybrid | 10 | None | 0 days |
Loom & Leaf | 10 | None | 0 days |
Company
The company analysis of Helix vs. Saatva shows that Saatva has a bit better company policies. It offers a longer trial period as well as a longer warranty.
Company | Helix | Saatva |
---|---|---|

3.5 out of 10
The Helix Moonlight is the softest Helix mattress we’ve tested and can be a good option for lightweight side sleepers.
The Saatva Classic (plush soft version) comes in three firmnesses, one being a “plush soft” firmness, which is also a 3.5 out of 10.

4 out of 10
The Helix Sunset is just a touch firmer than the Helix Moonlight and soft Saatva Classic, coming in at a 4 out of 10.

5.5 out of 10
If you’re looking for a touch softer, check out the Loom & Leaf or the Saatva Classic. These two mattresses are a 5.5 out of 10 on the firmness scale and have a plush feel to them, perfect for side sleepers or lighter sleepers especially.

6 out of 10
If you’re looking for a mattress that is likely to be enjoyed by the widest range of sleepers, you may want to consider something in the 6 out of 10 firmness range.
This would include Helix Dusk, Helix Midnight, Helix Midnight Luxe, Saatva Classic, or the Saatva Memory Foam Hybrid.

7 out of 10
If you’re looking for something that is a little firmer consider the Helix Plus. This mattress is specifically designed for heavier sleepers as well as back or stomach sleepers.

The Helix Kids is a flippable mattress with one side being 7 out of 10 and the other side slightly firmer at 8 out of 10. But one note, this mattress is designed for kids 12 and under.
8 out of 10
The Helix Dawn, Helix Twilight, firm version of the Saatva Classic, or firm version of the Loom & Leaf are all firmer options that are an 8 out of 10.
An 8 out of 10 would be more ideal for back or stomach sleepers, as well as heavier sleepers.

As you can see, not all firmnesses are suitable for all sleepers. It’s important to know your ideal firmness prior to purchasing a new mattress.
Design
The design of each of these mattresses is very different and we use the table below to outline the details of each mattress.
Design | Type | Mattress Thickness |
---|---|---|
Helix Midnight | Hybrid | 12.0″ |
Helix Midnight Luxe | Hybrid | 14.0″ |
Helix Plus | Plus-Sized | 13.0″ |
Saatva Classic | Coil | 11.5″ |
Saatva Memory Foam Hybrid | Memory Foam Hybrid | 11.5″ |
Loom & Leaf | Memory Foam | 12.0″ |
The Loom & Leaf is the only 100% foam mattress and doesn’t contain any coils.
The Helix collection is all hybrids, meaning that they are a combination of comfort foams and support coils. The Saatva Memory Foam Hybrid is also a hybrid, like Helix.
The Saatva Classic is primarily a coil mattress. It has a double layer of coils with a plush Euro-style cover. This mattress is the only one in this comparison that comes in two different firmness options—11.5″ or 14.5″.
If you’re specifically looking for a high-profile mattress, the Helix Midnight Luxe or the thicker version of the Saatva Classic are both 14″ or more.

Should You Buy the Helix Midnight Luxe?
I would recommend the Helix Midnight Luxe if you’re looking for:
- Low motion transfer. The Midnight Luxe has the lowest motion transfer among all mattresses tested in this comparison. If you are easily disturbed by your partner (or yourself), low motion transfer can be an important issue.
- Fantastic pressure relief. This mattress has a thick pillow top cover, thick layer of comfort foams, and a supportive coil base. These separate factors combined provide excellent pressure relief for all sleeping positions, but would be especially beneficial for side sleepers.

Should You Buy the Helix Plus?
I would recommend the Helix Plus if you’re looking for:
- Support for heavier sleepers. The Helix Plus has a 13″ thick profile, thicker comfort layers, and tied for the best edge support. These factors combined with the firmer feel make this mattress a good option for heavier sleepers (especially 300+ pounds).
- Fast response. This mattress also has the least amount of sinkage and the fastest response time among all mattresses tested in this review.

Should You Buy the Loom & Leaf?
I would recommend the Loom & Leaf if you’re looking for:
- Classic memory foam feel. The Loom and Leaf has a fast (but still relatively slower) response time, fantastic hug, excellent body contouring, and among the very best pressure relief out of all mattresses I’ve tested to date. If you like the feel of memory foam then you’ll love Loom and Leaf.
- Great pressure relief. If you’re looking for good hug and contour, the sleeping surface of the Loom & Leaf is one of the best I’ve tested to date.

Should You Buy the Saatva Classic?
I would recommend the Saatva Classic if you’re looking for:
- Best overall. The Saatva Classic had the best cooling, best edge support, best pressure relief, least amount of off-gassing, and best company score. These factors gave the mattress an overall score of 9.74, making it one of the best mattresses we’ve ever tested.
- More bounce. If you like the bounce and feel that a coil-on-coil mattress provides, you’ll likely enjoy the Saatva. More bounce is also be great for sex performance.

I would recommend the Saatva Memory Foam Hybrid if you’re looking for:
