Helix vs. Dreamcloud: Who Is the Winner?

The table below shows which of these mattresses is the winner in each scoring category we test for.

Factor	Winner	Score
Best Overall	Helix Midnight Luxe	9.32
Best Cooling	Helix Midnight Elite	10
Most Sinkage	Helix Sunset	3.07″
Least Sinkage	Helix Plus	1.50″
Lowest Motion Transfer	Helix Midnight Luxe, Dreamcloud Premier Rest	10
Fastest Response Time	Helix Plus	10
Most Bounce	Helix Moonlight	17.15″
Least Bounce	Helix Midnight Luxe	7.47″
Best Edge Support	Helix Plus	10
Best for Sex	Helix Moonlight	9.6
Best Pressure Relief	Helix Dusk Luxe, Helix Midnight Elite, Helix Midnight Luxe	10
Least Off-Gassing	Dreamcloud, Dreamcloud Premier, Dreamcloud Premier Rest	9.7
Best Company	Helix	9.5

Among these models, here are the categories where each mattress excelled.

• BEST COOLING: Helix takes the win over DreamCloud in all instances. While both of these brands make hybrids, the DreamCloud hybrids just struggled more in this area, compared to Helix.
• MOST / LEAST SINKAGE: The Helix Sunset recorded the most sinkage (also the softest feel) and the mattress with the least sinkage is the Helix Plus. The Plus is designed for plus-sized sleepers so it makes sense that sinkage is more limited. Dreamcloud fell in between these two mattresses, offering a moderate sinkage.
• LOWEST MOTION TRANSFER: In this category, DreamCloud Premier Rest takes the win. This mattress offers 4.0″ of comfort material and a 2.0″ thick plush, pillowtop. All of these layers help to deaden energy and limit motion transfer.
• FASTEST RESPONSE TIME: The Helix Plus has the fastest performance, with a 0.2-second response. This is tied with the fastest we’ve tested to date.
• MOST / LEAST BOUNCE: With the most bounce, the Helix Moonlight tops out at 17.15″ while the Helix Midnight Luxe has the least amount of bounce with only 7.47″.
• BEST EDGE SUPPORT: The Helix Dusk Luxe and Helix Midnight Luxe had the best edge support with a max sinkage of only 3.0″.
• BEST FOR SEX: Regarding sex, the Dreamcloud Premier was the leader, striking a fantastic balance between bounce, edge support, cooling, pressure relief, and noise.
• BEST PRESSURE RELIEF: The Helix Dusk Luxe and Helix Midnight Luxe were both tied for best pressure relief. These Luxe mattresses offer great pressure relief thanks in part to their thicker profile and pillow-top cover layer.
• LEAST OFF-GASSING: The Dreamcloud takes the win here with only a minor smell out of the box and a single day of off-gassing.

So with these honorable mentions in mind, let’s get rolling and dive into the details of these mattresses.

Helix Plus Cooling Test

Dreamcloud Cooling Test

Dreamcloud Premier Cooling Test

Dreamcloud Premier Rest Cooling Test

The sinkage levels vary pretty widely between Helix and Dreamcloud. Helix ranges between very minimal to moderate. Dreamcloud ranges from minimal 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″
Dreamcloud	Extremely Deep	3.02″
Dreamcloud Premier	Minimal	1.94″
Dreamcloud Premier Rest	Moderate	2.18″

The average level of sinkage across all mattresses tested to date is 2.2″.

Based on these numbers, all of these mattresses have less sinkage than average with the one exception being the Dreamcloud original hybrid.

The Dreamcloud original has almost a full inch more sinkage than all of the other mattresses in this comparison.

Images below show the level of sinkage for each mattress.

Motion transfer was fast for most of the mattresses in this comparison.

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
Dreamcloud	9.7	5.60 m/s²
Dreamcloud Premier	9.7	5.67 m/s²
Dreamcloud Premier Rest	10	2.62 m/s²

The average amount of motion transfer is 5.83 m/s² (based on all of our tests to date).

Based on this average, the Dreamcloud Premier Rest and Helix Midnight Luxe have significantly less motion transfer than average.

The Dreamcloud original and Dreamcloud Premier are about average.

The Helix Midnight and Helix Plus have more motion transfer than average.

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.

Dreamcloud Motion Transfer Test

The Dreamcloud Original is about at the average for motion transfer. As you can see, there is a big amount of energy from the initial drop, but by 0.8 seconds, the energy has mostly been absorbed.

Dreamcloud Premier Motion Transfer Test

The Dreamcloud Premier also had about average levels of motion transfer. Again we can see the energy from the initial ball drop in our test, with motion being mostly absorbed by the 1-second mark.

Dreamcloud Premier Rest Motion Transfer Test

The Dreamcloud Premier Rest has significantly less motion transfer than the other Dreamcloud mattresses, as well as all of the Helix models.

The same ball drop as the other tests only generated about 1/3 of the energy on the Premier Rest compared to the Premier or Dreamcloud original hybrid. Furthermore, the energy was absorbed by 0.73 seconds.

The response time on the Helix mattresses largely outperforms the response on most of the Dreamcloud mattresses.

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
Dreamcloud	5.0	5.0 seconds	6.0 seconds
Dreamcloud Premier	5.9	0.9 seconds	1.5 seconds
Dreamcloud Premier Rest	5.0	3.7 seconds	4.5 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 and Helix Plus are the only two mattresses to actually perform better than average.

The Helix Midnight and Dreamcloud Premier followed closely behind and were just slightly beyond the average.

But the Dreamcloud Original and Dreamcloud Premier Rest were significantly slower than average. In fact, these two mattresses are the slowest mattresses we’ve tested to date (among over 130 mattresses that we’ve reviewed).

You can see these material responses in real-time in the video below.

The level of bounce has a pretty wide variance, 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″
Dreamcloud	High	11.20″
Dreamcloud Premier	High	11.03″
Dreamcloud Premier Rest	Low	7.88″

The average amount of bounce across all mattresses tested to date is 9.35″.

So where do Helix and Dreamcloud fit in?

The Helix Midnight Luxe has less bounce than average, at 7.47″ with the Dreamcloud Premier Rest recording a similar score at 7.88″ total bounce.

The Helix Plus was about at the average with 9.38″ of total bounce.

With higher bounce than average, we have the Dreamcloud Original, Dreamcloud Premier, and the Helix Midnight.

Bounce levels can also be viewed in real-time via the short video clips below.

Concerning edge support, there are definitely some of these mattresses that excel while others leave room for some concerns.

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
Dreamcloud	8.3	5.00″	Excellent
Dreamcloud Premier	9.1	3.75″	Excellent
Dreamcloud Premier Rest	6.5	5.50″	Mediocre

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, and Dreamcloud Premier all have less edge sinkage than average.

By comparison, the Dreamcloud Original, Dreamcloud Premier Rest, and Helix Midnight all have more edge sinkage than average.

I will note here that even though sitting edge sinkage on the Dreamcloud Original hybrid was beyond the range I prefer to see, lying edge support was excellent.

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
Dreamcloud	9.0	9.5	7.5	10	8.0	8.0
Dreamcloud Premier	9.2	9.4	9.1	10	8.0	7.0
Dreamcloud Premier Rest	7.4	7.4	6.9	10	8.0	7.0

The sex performance of all of these mattresses is fantastic for most of these mattresses.

Top-performing mattresses include the Dreamcloud Original hybrid and Dreamcloud Premier which had scores in the 9’s. and the with scores in the upper 9’s.

The Helix Midnight and Helix Plus followed closely behind with a score of 8.6—the biggest disadvantage of this mattress being the noise from the springs.

The Dreamcloud Premier Rest and Helix Midnight Luxe had the lowest performance in this category with scores in the 7’s. Considering that both of these mattresses have lower bounce levels as well as pillow-top cover layer, these results were not that surprising.

Pressure relief on Dreamcloud was good (not great) and the Helix mattresses outperformed in this category.

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″
Dreamcloud	8.0	5.5″	8.5″
Dreamcloud Premier	8.0	5.5″	8.5″
Dreamcloud Premier Rest	8.0	6.5″	9.5″

All of the Helix mattresses had scores between 9.0-10, but the Dreamcloud scores were 8.0. This is interesting in one way because the Dreamcloud mattresses actually have thicker comfort layers than Helix.

In many cases, thick comfort layers can be good indicators of better pressure relief since your body can engage more deeply without feeling pushback from deeper layer support.

But comparing Helix vs. Dreamcloud, Helix had better pressure relief, despite having thinner comfort layers than Dreamcloud.

Moving right along, let’s talk about off-gassing. Off-gassing isn’t a huge problem for the Helix or Dreamcloud mattresses.

On average, most mattresses take around 3.5 days to off-gas. Every mattress that we tested here was faster than that.

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
Dreamcloud	9.7	Minimal	1 day
Dreamcloud Premier	9.7	Minimal	1 day
Dreamcloud Premier Rest	9.7	Minimal	1 day

The company analysis of Helix vs. Dreamcloud shows that Dreamcloud has a bit better company policies. It offers a longer trial period as well as a longer warranty.

Company	Helix	Dreamcloud
Score	9.5	9
Trial Period	100 nights	365 nights
Warranty	10 years	Lifetime
Shipping	$0	$0
Returns	$0	$0
Trust	Outstanding	Good
Country of Origin	USA	USA

Helix offers a trial of up to 101 nights and a 25-year warranty. This is compared to Dreamcloud which has a 365-night trial period and lifetime warranty.

Between Helix and DreamaCloud, there is a very wide firmness range. Dreamcloud offers mattresses in the medium to medium-firm range, but Helix’s collection spans the full range of firmness from soft to firm.

Firmness	Rating	Feel
Helix Dawn	8	Firm
Helix Dusk	6	Medium-Firm
Helix Dusk Luxe	6	Medium-Firm
Helix Kids	7	Slightly Firm
Helix Midnight	6	Medium-Firm
Helix Midnight Elite	5.5	Medium
Helix Midnight Luxe	6	Medium-Firm
Helix Moonlight	3.5	Extra Soft
Helix Plus	7	Slightly Firm
Helix Sunset	4	Soft
Helix Twilight	8	Firm
Dreamcloud	7	Slightly Firm
Dreamcloud Premier	7	Slightly Firm
Dreamcloud Premier Rest	6	Medium-Firm

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.

4 out of 10

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

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 Dreamcloud Premier Rest, Helix Dusk, Helix Dusk Luxe, Helix Midnight, and the Helix Midnight Luxe.

7 out of 10

If you’re looking for something that is a little firmer consider the Dreamcloud Original, Dreamcloud Premier or the Helix Plus. Both the Premier and the Plus are good picks for lightweight to moderate-weighted back or stomach sleepers.

The Helix Plus is specifically designed to support heavier-weighted sleepers.

FOR KIDS: If you’re shopping for a child, you can also consider the Helix Kids—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 Dawn Luxe, Helix Twilight, and Helix Twilight Luxe all have a firmness of 8 out of 10.

An 8 out of 10 would be a more ideal firmness for heavier back or stomach sleepers.

If you’re not sure which firmness is best for you, check the table below. This table provides a recommended firmness range, based on sleeping position and sleeper body weight.

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

All Dreamcloud and Helix mattresses in this review are classic hybrids. They have a pocketed coil base with foam comfort layers. Some mattresses, but not all, also have a pillow-top cover layer.

Design	Type	Mattress Thickness
Helix Midnight	Hybrid	12.0″
Helix Midnight Luxe	Hybrid	14.0″
Helix Plus	Plus-Sized	13.0″
Dreamcloud	Hybrid	14.0″
Dreamcloud Premier	Hybrid	14.0″
Dreamcloud Premier Rest	Hybrid	16.0″

Images below show exactly what is on the inside of each of these mattresses. Let’s take a look.

Which Mattress Should You Buy?

Comparing Helix vs. Dreamcloud, there are advantages and disadvantages to both brands. Ultimately, your individual sleeper preferences and needs will determine which is the better option for you.

Should You Buy the Helix Midnight?

I would recommend the Helix Midnight if you’re looking for:

• Lower price point. The Helix Midnight is a more budget-friendly version of the Helix Midnight Luxe and is a great value.
• Balanced feel. This mattress has a balanced feel with a respectable score (8.58 overall).

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 Dreamcloud?

I would recommend the Dreamcloud Original Hybrid if you’re looking for:

• Classic memory foam. This mattress has a slower response time and could be more closely compared to the feel of classic memory foam, offering more hug and a deeper level of sinkage.
• Budget price. If you need a mattress under $1000 for a queen, the Dreamcloud is still a solid option. Although performance may not match that or Helix, it is still a solid mattress if you’re on a budget and like the feel.

Should You Buy the Dreamcloud Premier?

I would recommend the Dreamcloud Premier if you’re looking for:

• Low levels of motion transfer. The Dreamcloud Premier offers low levels of motion transfer, which can be great for sensitive sleepers.
• Higher levels of bounce. Despite the limited motion transfer, this mattress still has higher levels of bounce, compared to the other hybrids in this comparison—a total of 11.03″.

Should You Buy the Dreamcloud Premier Rest?

I would recommend the Dreamcloud Premier Rest if you’re looking for:

• Lowest levels of motion transfer. The Dreamcloud Premier Rest has the lowest levels of motion transfer, among all mattresses tested in this comparison.
• Pillow-top cover. The Premier Rest offers a 2.0″ pillow-top cover which can be advantageous to sleepers looking for that plush top feel.
