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	Moderate
Motion Transfer	Extremely High
Response Time	Extremely Fast
Bounce	High
Edge Support	Excellent
Sex	Excellent
Pressure Relief	Very Good
Off-Gassing	Excellent
Company	Excellent

The cooling performance on the Happsy mattress is excellent. During our tests, I felt no significant level of heat retention around my body.

This is pretty typical performance for a latex hybrid mattress. Latex doesn’t retain heat and also breathes well. Meanwhile, the pocketed coil layer creates ample air flow for the mattress as a well.

• 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

In terms of material choices and mattress design, the Happsy mattress checks the boxes I look for.

Looking at our objective data we see good, but not amazing performance. In our tests, we recorded a max temp of 89.0°. This is 0.5°F cooler than the average max temp (based on all of our tests to date).

Heat dissipation was about the same, good, but far from great. From minutes 0 to 1 we recorded a decline of 2.5°, which is notably worse than average. The decline from minutes 0 to 5 was also below average.

Heat Dissipation Over Time

It’s unclear to me why the objective data is so lackluster compared to our subjective experience. It’s possible that the materials within the quilted cover are retaining heat more aggressively, compared to the core and support layers of the mattress, which create a more cool experience.

In any case, while I am not thrilled with the objective data we recorded, I am inclined to believe what my body and the material design tell me; which is, this is an acceptably cool mattress.

There is nothing within the Happsy mattress that would lead to poor cooling performance.

The Happsy mattress has a moderate level of sinkage. In our tests, we measured a pressure point sinkage depth of 2.20”.

This is nearly the same as the average sinkage depth (based on all of our tests to date), which is 2.25”.

The level of sinkage is documented in the image below.

The mattress has a very restrained and generalized contour around the body.

This is in contrast to memory foam and many poly foam mattresses, which create a more dramatic and exacting hug around the body.

While the midsection and butt sink deeper into the mattress, other lighter parts of the body (especially arms and legs) are floating more on top of the mattress.

Given the latex hybrid design, this is basically what I expect as far as the feel goes.

The Happsy mattress has an extremely high level of motion transfer. In our tests, we measured a total acceleration range of 15.91 m/s².

This is significantly higher motion than we see on average. Based on all of our tests to date, we have measured an average motion transfer rate of 6.90 m/s².

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

At an acceleration range of 15.91 m/s² the Happsy mattress has the 5th highest motion transfer of any mattress we’ve tested to date.

When we consider the design of the mattress, it makes sense. Both latex and coils individually will create a higher level of motion transfer.

A thicker latex foam comfort layer could help to reduce motion, but with only 2.0” of latex foam it’s just not enough to dramatically suppress motion transfer. As a result, we end up with a very high level of motion transfer.

If we look at our motion transfer chart, which visualizes our accelerometer data, we see the highest motion from 0.00 to 0.77 seconds.

Motion drops off after 0.77 seconds, but it isn’t until 1.13 seconds that it returns to near zero levels. Both the motion intensity and motion duration are considerably higher / worse than average.

The Happsy has an extremely fast response time. 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 effectively instant and also tied for 1st with many other mattresses for the fastest responding mattress we’ve tested to date.

The level of responsiveness is documented in the video below.

Both latex and coils spring back to shape instantly. When you combine them together you end up with a mattress that’s able to rebound back to shape so you’ll never have any difficulties moving around or getting in / out of bed.

The Happsy mattress has a high level of bounce. In our tests, we measured a total bounce height of 11.71”. This is 2.08” more bounce than the average of 9.63”.

Looking at the materials and design, it’s no surprise that we see a high bounce. Both latex and coils by themselves create ample bounce, and together they have even more bounce.

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

While bounce is a preferential factor, in general, higher levels of bounce are better. Higher bounce makes it easier to move around, prevents any stuck feeling, and improves sex.

At 11.71”, the Happsy has plenty of bounce to enjoy all of the benefits of higher bounce. However, that higher bounce does negatively impact motion transfer (which we discussed above).

The Happsy mattress has excellent edge support for both sitting and lying. In our sitting edge support tests, we measured a total sitting sinkage depth of 3.25”. This is significantly better than the average.

Based on all of our tests to date, on average, we have measured 4.55” of sitting sinkage. With a thinner 2.0” latex comfort layer, the Happsy has a highly supportive edge (since you very quickly engage with the support coils).

While this doesn’t do it any favors for pressure relief, it is greatly beneficial for edge support.

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

Lying edge support was equally as impressive. I felt well supported in all sleeping positions even when lying on the absolute edge. This was a bit surprising.

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

Typically, latex hybrids struggle with lying edge support, as latex often just isn’t supportive at the very edge of the foam.

As we saw with sitting edge support, the thinner 2.0” latex comfort layer helps ensure that lying edge support is better, as sleepers engage more with the coils.

To score sex performance we look at a number of different factors that all play a role in quality sex. Factors include bounce, edge support, noise, pressure relief, and cooling.

All factors are not equal in terms of significance, but bounce, edge support, and noise are the 3 most important.

Here’s a look at our complete sex formula which outlines where each factor falls.

We use the following scores, plugged into the formula, to derive a sex score for each mattress.

Sex Factor	Factor Weight	Score
Bounce	60%	10
Edge Support	20%	9.9
Noise	10%	10
Pressure Relief	5%	9.0
Cooling	5%	9.5

For the Happsy mattress, these individual factors generated a sex score of 9.9.

This is a near-perfect score and overall, it does a lot right. Happsy offers high levels of bounce and excellent edge support, which is fantastic for sex.

It is quiet, has good cooling, and has sufficient pressure relief. A thicker comfort layer would have likely improved the pressure relief, but it may also have negatively impacted the bounce, so it’s a bit of a double-edged sword.

Pressure relief on the Happsy mattress is good, but far from great. In our tests, I felt a slight to moderate degree of building pressure, especially in my hips and shoulder blades.

The Happsy only uses a 2.0” latex comfort layer. Ultimately, this just isn’t a very thick comfort layer. The best pressure relieving mattresses have a 4-6” thick comfort layer.

The thinner profile means sleepers sink more quickly through the foam and into the support coils.

When it comes to heavier sleepers, curvier bodies, and the heavier portions of even moderate / lightweight bodies (hips, butt, shoulders, etc.) you end up engaging more significantly with those coils, which creates the potential for pressure.

Fortunately, Happsy does offer a pillow top add-on, which will certainly improve pressure relief.

In my view, if you have any concerns at all about pressure relief then I would strongly recommend adding the pillow top to ensure your needs are met.

Off-gassing on the Happsy mattress is very good. Right out of the box, it had only a minimal smell. After the first day, it was fully off-gassed.

This is likely due to the organic materials and hybrid construction.

It has more of a latex / rubber smell than anything else. It’s not nearly as offensive as more typical memory / poly foam off-gassing is.

The Happsy brand has a good company score, with a 120-night trial period, a 20-year warranty, and free shipping and returns.

The Happsy mattress is a medium firmness which comes in at 6 out of 10 on the firmness scale, where 10 is the most firm.

The Happsy mattress has excellent support. During our tests, I felt well supported in all sleeping positions.

It uses a typical, but proven, material layer design with natural latex on top of pocketed coils. The quality of both the natural latex and coils feels strong and I don’t have any concerns about longevity.

My only significant support concern is for heavier sleepers, especially 250 and up. Happsy only uses 2.0” of comfort material, which just isn’t very much.

Sleeper Weight	Stomach Sleepers	Side Sleepers	Back Sleepers
Under 150 lbs.	Yes	Yes	Yes
150-250 lbs.	Yes	Yes	Yes
250-300 lbs.	Maybe	Maybe	Maybe

The limited comfort layer could cause heavier sleepers to feel pressure on the heavier portions of the body. For most sleepers, the performance of the Happsy will be considerably improved by adding the optional pillow top.

Design

The Happsy mattress is an organic latex hybrid with a 10″ profile, simple design, and medium firmness.

Materials

From top to bottom, there are only two layers on the Happsy mattress.

• Top: 2.0″ natural latex
• Bottom: 8.0″ pocketed coils

The Cover

The cover of the Happsy mattress has an organic cotton fabric with organic wool batting directly below quilted together.

This gives the top a feeling of softness, but by using materials that actively combat the feeling of heat retention.

The Comfort Layer

The comfort layer is a 2.0″ slab of organic latex with fluted perforations towards the bottom of the slab.

The Support Layer

Below the latex is the 8.0″ layer of pocketed coils. This support layer has each coil encased in a thin layer of fabric, which helps to reduce noise and also limit motion transfer.

Product Evolution

The Happsy mattress was launched in 2019 and has undergone no significant design or material changes since the launch.

If / when materials or design are updated we will make updates to this section.

How is Happsy Different?

So how is Happsy different from the competition? There are a couple stand-out features.

#1. Organic + Natural

Happsy uses organic latex, organic cotton, and organic wool. And it skips things like glues, adhesives, and chemical flame retardants.

The mattress also meets the criteria to be certified under the Global Organic Textile Standard.

#2. Optional Topper

On its own, the Happsy mattress doesn’t really have fantastic pressure relief, but that does help keep the cost low. If you find that you need more pressure relief, they offer an optional mattress topper.

This topper ranges in price from $249-499, depending on what size you need, but provides an additional 2″ of comfort material. The topper will dramatically improve pressure relief for all sleepers.
