At NapLab, we put each mattress to the test.

We test 10 different factors that impact the performance, comfort, and value of the mattress. Testing categories include:

Test	Rating
Cooling	Excellent
Sinkage	Minimal
Motion Transfer	Very Low
Response Time	Extremely Fast
Bounce	Low
Edge Support	Excellent
Sex	Excellent
Pressure Relief	Excellent
Off-Gassing	Excellent
Company	Exceptional

Cooling performance on the Douglas Alpine was excellent. During our tests, I felt no significant level of heat retention around my body.

The Alpine mattress uses a phase change material (PCM) within the cover. These PCM fibers create a “cool to the touch” feel. Notably, it will heat up to body temperatures over time.

However, the cooler initial feel is great to help you get to sleep and also provides a cooling effect each time you change positions or move around on the mattress.

• 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 (5 minute) – the temperature of the mattress after being lied upon and having no one on it for 5 minutes

The all-foam design limits cooling performance to a degree. Ultimately, there’s just only so much an all-foam mattress can do. Even so, the Alpine does what it can, the foams seem to breathe well, and the cooling cover is a nice addition.

In our objective testing, we measured a maximum surface level temperature of 87.1°. From minutes 0 to 1 the temperature dropped by 5.7°, with minutes 0 to 5 dropping by 11.2°.

Heat Dissipation Over Time

Compared to the more expensive Douglas Summit mattress, the minute-by-minute heat dissipation was essentially the same. Overall, I’m pleased with the cooling performance.

The Douglas Alpine has a minimal level of sinkage. In our pressure point sinkage tests, we measured a sinkage depth of 1.81”. This is 0.41” less sinkage than the average of 2.22”.

The level of sinkage is documented in the image below.

While pressure point sinkage was a bit more restrained, the sinkage around my entire body felt far more moderate in its depth. Notably, my butt and mid-section sank a good bit more.

While the Alpine does not use any memory foam, the foam has many of the same qualities of memory foam. The mattress creates a sharp and exacting hug around the body, as it contours to each sleeper’s unique shape.

However, unlike memory foam, the feel is far cooler, not as dense / hard, and responds more quickly (which we’ll discuss more below).

The Douglas Alpine has a very low level of motion transfer. In our tests, we measured 5.89 m/s² of acceleration range. This is 1.74 m/s² less motion than the average, based on all of our tests.

The level of motion transfer is documented in the video below.

The all-foam design, 11” total thickness, and medium-firm feel all work together to help keep motion quite restrained.

Looking at our motion transfer chart, which visualizes our accelerometer data, we see the highest motion peak from 0 to 0.14 seconds.

Motion drops dramatically thereafter and by 0.63 seconds it’s back to near zero. While the motion spikes aren’t the absolute lowest we’ve seen, the motion duration is quite low.

Overall, I’m impressed by the motion transfer on the Alpine. It does a great job at reducing motion-generating events quickly.

The Douglas Alpine has an extremely fast material response. In our tests, we measured a mostly recovered response time of 0.2 seconds and a fully recovered response time of 0.3 seconds.

This is tied with the fastest-responding mattresses we’ve tested to date. The Alpine manages to create the pressure-relieving comfort of memory foam, while also having a rapid response time.

The level of responsiveness is documented in the video below.

The mattress rebounds back to shape at the same speed as natural latex. The faster response helps ensure sleepers won’t feel stuck and makes it easier to move around on the mattress.

The Douglas Alpine has a low level of bounce. In our tests, we measured 7.32” of total bounce height. This is 2.38” less bounce than the average of 9.70”.

The lower level of bounce helps to keep motion transfer quite restrained. However, it also decreases the ease of movement and makes sex notably worse. The all-foam design of the mattress does the bounce no favors.

The level of bounce is also documented in the video below.

While bounce is a preferential factor, you should carefully consider if the low bounce would work for you.

Some sleepers who have historically slept on coil mattresses have a hard time transitioning to all-foam mattresses, especially when the bounce is so low.

Edge support on the Douglas Alpine is excellent for both sitting and lying. In our sitting edge support tests, we measured 3.25” of sitting sinkage.

This is 1.14” less sinkage than the average, based on all of our tests to date.

In general, I like to see 4.00” of sitting sinkage compression or less. The Alpine hits and exceeds that mark.

As a result, I felt extremely well supported while sitting even directly on the edge of the mattress. Edge support while lying was equally as good.

The level of edge support while seated is documented in the images below.

The level of edge support while lying is documented in the images below.

During our tests, I felt well-supported while lying directly on the edge of the mattress. The foams are of high quality, have an appropriate firmness, and the 11” thickness all work together to create excellent edge support.

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.

Three of the most important factors are listed below with the associated testing scores:

In addition to the factors above, there are two other we consider as well, including pressure relief and cooling.

Here’s a look at the breakdown of how these 3 factors rank within the full formula:

We use the scores from all factors, plugged into the formula above, to derive a sex score for each mattress.

Sex Factor	Factor Weight	Score
Bounce	60%	9.3
Edge Support	20%	9.9
Noise	10%	10
Pressure Relief	5%	9.5
Cooling	5%	9.5

For the Douglas Alpine, these individual factors generated a sex score of 9.5.

This mattress has a low bounce, which tends to hold the score down. When it comes to good sex performance, bounce is critically important to keep things active and engaging.

But bounce aside, the Alpine mattress has good edge support and is very comfortable overall.

The Douglas Alpine has excellent pressure relief. Throughout our tests and in all sleeping positions I felt no pressure point build up on my body.

The 4.5” comfort layer does a nice job at creating good pressure relief. Notably, the Alpine does not use memory foam. Instead, it uses gel foam and poly foam.

Despite this, the mattress feels like many other modern memory foam mattresses I’ve tested. It creates excellent pressure relief through an exacting contouring hug around the body.

Unlike memory foam, it has a rapid response on par with natural latex, does not significantly retain body heat, and is not heat reactive (ie, won’t get softer / firmer based on the temperature in the room / on the mattress).

Overall, I’m pleased with the pressure relief performance and I believe most sleepers will find pressure relief to be excellent.

Off-gassing on the Douglas Alpine was strong when we initially unboxes the mattress, but that’s not exactly uncommon.

The smell gradually dissipates over the course of a couple of days and by day 5, the odor was completely gone.

To help a mattress off-gas faster, leave the mattress in a well-ventilated room and without any bedding or other sheets. Add a fan or air purifier to maximize airflow.

The Douglas Alpine mattress is sold by GoodMorning.com, which also produces a number of other mattresses including Full Moon, Logan & Cove, and Novosbed.

The Douglas Alpine mattress is a 6 out of 10 on the firmness scale. This is a medium firm feel and is suitable for a wide range of sleepers.

The Douglas Alpine has excellent support. In our tests, I felt fully supported in all sleeping positions. The mattress has a proven layered design and uses robust, high-quality foam materials.

The Alpine uses a 4.5” of comfort foam and 6.5” of support foam. With respect to comfort materials, I like to see a minimum of 3.0” and 4.0”+ whenever possible.

The mattress hits and exceeds that mark, which enables the right mix of comfort, pressure relief, and transitional support for sleepers.

While the 6.5” support foam could be slightly thicker, it’s still dense and thick enough to create good support. I expect most sleepers will find support to be perfectly acceptable. 

Based on this subjective assessment, the Douglas Alpine would be supportive for all sleeper profiles noted below:

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

Design

The Douglas Alpine mattress is an all-foam mattress with an 11″ profile and a medium firm feel (6 out of 10 on the firmness scale).

Materials

Within the 11″ profile, there are three primary layers on the Douglas Alpine mattress. From top to bottom, these layers include:

• 2.25” gel foam
• 2.25” poly foam (Elastex)
• 6.5” support foam

The top layer acts as a comfort layer, middle layer is a transitional layer, and the base layer is a support layer that helps

The Cover

The cover of the Douglas Alpine mattress is made of the same fabric as the original Douglas and Douglas Summit. It’s a lightweight, moisture-wicking, stretchy cover designed for breathability and easy maintenance. The cover easily zips right off the top of the mattress and is machine washable.

The Comfort Layer

The top comfort layer is 2.25″ gel foam which provides good compression and contour, without retaining heat.

Directly below the gel foam is a transitional poly foam called Elastex. This foam has a firmer feel than the comfort gel foam and improves response time as well.

The Support Layer

The bottom layer of the Douglas Alpine mattress is a high-density support foam. This foam is designed to support the layers above and help provide deep pressure relief.

Product Evolution

The Douglas Alpine launched at the end of 2022, the same time as the Douglas Summit mattress hit the market. Since its launch, it has undergone no notable design changes.

How is the Alpine Different?

The Douglas Alpine is a high-quality Canadian mattress. According to NapLab data, the average price for a Canadian mattress is C$1155 for a queen.

At C$999, the Douglas Alpine is a great budget option, saving you 14% off of the average price.

In addition to the savings, the Douglas Alpine is still a solid performer with a score of 9.72 overall. This score is above the average score of all foam mattresses we’ve tested (9.48).

This puts the Douglas Alpine in the top 15% of all foam mattresses we’ve tested to date.

As an added fun fact, the top three foam mattresses we’ve tested to date are all Douglas mattresses, with scores ranging from 9.72 – 9.84.
