Best For

  • Budget-friendly, a great value at this price point
  • Very low motion transfer, 2.30 m/s²
  • Fast response, bounces back within 0.3 seconds

Considerations

  • Very low bounce, which does improve motion transfer, at the cost of sex performance
  • Cooling performance is good, but not great
  • Edge support leaves quite a lot to be desired

Our Verdict

The Full Moon mattress is an extremely budget-friendly mattress option. It uses a simple design of poly foam and high-density support foam with a soft, stretchy cover.

This is an inexpensive mattress, so the bar should be lower. Yes, performance lacks in many areas, however, it’s a value / budget-friendly mattress. So you will give up something to get this price point.

During our performance tests, the Full Moon mattress had good (but not great cooling), minimal sinkage, very low motion transfer, very fast response time, low bounce, and okay pressure relief (best for stomach or back sleepers).

Type: Poly Foam
Firmness: Medium (6)

Performance Tests

At NapLab, we put each mattress to the test.

We test 9 different factors that impact the comfort and feel of the mattress. Testing categories include:

Cooling Test

The cooling performance on the Full Moon mattress is good, just not great. During our tests, I did not feel excessively hot, though I did feel a minor to moderate level of heat retention. Given the material construction, it makes sense.

Baseline Temp.

75.7° F

Max Temp.

86.2° F

Ending Temp.

79.1° F

While the Full Moon uses poly foam instead of memory foam, airflow is still limited due to all-foam construction, which limits breathability. While the level of heat retention is higher, I was pleased with the heat dissipation curve.

Max Temp.

Ending Temp

Full Moon after cooling test

  • 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

Within 1 minute after getting off of the mattress the surface level temperature dropped from 86.2 to 82.2° F. The Full Moon continued to further reduce the temperature over the 5 minute recording period, ending at 79.1° F.

The decline from 0 to 1 minute is 4.0° F, while the decline from 2 to 5 minutes is 1.5° F.

Heat Dissipation Over Time

Time ElapsedTemperature
1 minute82.2°
2 minutes80.6°
3 minutes80.1°
4 minutes79.3°
5 minutes79.1°

This speaks to a mattress that is able to more quickly dissipate heat. While it will likely sleep warmer for many sleepers, as you change positions during the night it should release that retained heat relatively quickly.

Given the price point of this mattress, the limited cooling performance is to be expected.

Sinkage Test

The Full Moon mattress has a minimal level of sinkage. In our tests, we measured a sinkage depth of 1.69”. This is considerably lower than the average sinkage depth across all mattresses we’ve tested to date, which is 2.21”.

The level of sinkage is documented in the image below.

Full Moon sinkage test
Full Moon sinkage test

The Full Moon has the 5th least sinkage among any mattress we’ve tested thus far. Since the Full Moon only has 2.0” of comfort material, there is only so much that the mattress is able to compress before hitting the more supportive base foam.

This limited sinkage depth makes the Full Moon mattress less than ideal for many side sleepers.

Side sleepers need more sinkage to create the right contour and support. For lighter weight side sleepers you may still find the Full Moon acceptable, but for moderate or heavier weight side sleepers it isn’t a mattress I would recommend.

See our support and sleeping position section further down the page for a deeper explanation of which positions and weights are best supported by the Full Moon.

Motion Transfer Test

Motion transfer was very low on the Full Moon mattress. In our motion transfer tests, we measured an acceleration range of 2.30 m/s^².

Max. Acceleration

1.11 m/s²

Min. Acceleration

-1.19 m/s²

Accel. Range

2.3 m/s²

This is significantly better than the average motion transfer across all mattresses we’ve tested to date, which is 5.86 m/s^².

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

The material construction of the Full Moon is creating the super low motion transfer. The all-foam design helps, as does the limited 2.0” comfort layer.

Full Moon motion transfer chart

Both of these factors combine to massively absorb energy and reduce motion transfer.

While there is certainly a trade-off in pressure relief, support, and other areas, at least with respect to motion transfer, the material design is a positive factor.

10

Response Test

The response time on the Full Moon mattress is very fast. In our tests, we measured a mostly recovered response time of 0.3 seconds and a full material recovery at 0.4 seconds.

Mostly Recovered

0.3 sec.

Complete Recovery

0.4 sec.

This is considerably faster than the average, which is 0.57 seconds to mostly recover and 0.94 seconds to fully recover.

The level of responsiveness is documented in the video below.

The Full Moon mattress uses a responsive poly foam as the comfort layer, as opposed to memory foam.

Memory foam is known for its deeper contour and slower time to respond and return to its original shape. Going with a poly foam instead of a memory foam helps ensure response time is faster and sleepers never feel stuck or trapped by the foam layer contours.

Bounce Test

The Full Moon mattress has a very low bounce height. In our tests, we measured a total bounce height of just 5.66”.

Max. Depth

4.97″

Max. Rebound

0.69″

Total Bounce

5.66″

This is significantly lower than the average bounce height across all mattresses we’ve tested to date, which is 9.40”.

Max. Sinkage Depth

A total of 5.66” of bounce just isn’t very much. The Full Moon mattress has more of a “dead” feel when it comes to bounce, which may not be ideal for all sleepers.

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

This is in contrast to more traditional mattresses, which have moderate to high levels of bounce. For some sleepers, this may not be a big deal, while others may really dislike the lack of bounce. With respect to sex, the lack of bounce is a major hit.

8.5

Edge Support Test

Edge support on the Full Moon mattress just isn’t good, at least while sitting. While sitting directly on the edge of the mattress we measured 6.0” of compression.

Max Sinkage

6.0″

Lying Support

Very Good

For a mattress that’s only 8.0” thick, that’s effectively a full material collapse. On average, we see 4.66” of sinkage when sitting directly on the edge.

However, being average isn’t good when it comes to edge support. Ideally, I’m looking for 4.0” or less of sinkage while sitting on the edge. And that’s usually in the context of a mattress that is 10-12″.

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

Sitting, 140 lbs.

Given the material construction and total thickness, that type of edge support isn’t surprising. If you do plan to use the edge of the mattress for sitting or sex you may be disappointed.

Edge support while lying on the mattress is good, but not great. I felt reasonably well supported while lying directly on the edge, but it’s certainly not as good as many other mattresses I’ve tested.

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

All of that said, while edge support does leave something to be desired it’s hard to complain too much. The Full Moon is extraordinarily inexpensive. At this price point, I don’t think you can expect to get much better.

8.9

Sex Test

To score sex performance we look at a number of different factors that all play a role in quality sex. Three of the most important factors include:

Bounce

8.9

Edge Support

8.5

Noise

10

In addition to the factors above, there are a few other things to consider as well, like pressure relief and cooling.

Here’s a look at our complete sex formula:

Sex Score Formula = (Bounce * 0.6) + (Edge Support * 0.2) + (Noise * 0.1) + (Pressure Relief * 0.05) + (Cooling * 0.05)

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

Sex FactorFactor WeightScore
Bounce60%8.9
Edge Support20%8.5
Noise10%10
Pressure Relief5%9.0
Cooling5%9.0

For the Full Moon mattress, these individual factors generated a sex score of 8.9.

The two biggest issues for this mattress are bounce and edge support—neither is very good.

Bounce is an important part of good sex and typically helps to make the dance with no pants more engaging and enjoyable. Sex on a mattress that can’t bounce back can feel flat and boring.

Full Moon edge support - sitting
Full Moon edge support – sitting

In addition to bounce, edge support is also critical. The edge support on the Full Moon is essentially non-existent when sitting directly on the edge. While this may not be a factor for everyone, for some, it’s a dealbreaker.

Noise, pressure relief, and cooling were all good scores, and not really a player in the strikes against the Full Moon mattress.

9.0

Pressure Relief Test

Pressure relief on the Full Moon mattress is a bit of a mixed bag. Based merely on my personal experience, I felt that the Full Moon did a nice job at relieving pressure relief.

It’s not the absolute best I’ve tested, but it’s certainly not bad.

Comfort Layer

2.0″

Support Layer

6.0″

Even so, looking at the material design of the Full Moon mattress has me concerned. With only 2.0” of comfort foam there just isn’t much between the top layer of the mattress and the harder support layer.

Full Moon stomach sleeping

Sleepers that are over 180 pounds, but especially those that sleep on their side, are likely going to be disappointed in the level of pressure relief. This is simply because heavier sleepers and side sleepers put more pressure on the mattress and need a thicker comfort layer to feel adequate pressure relief.

If you are a lighter-weight side sleeper (150 pounds or less) or you’re a back or stomach sleeper (no more than 200 pounds) then the Full Moon may be a good fit.

For sleepers outside of this threshold, I’m hesitant to strongly recommend it, simply due to the limited pressure relief that 2.0” of comfort material is able to provide.

9.6

Off-Gassing Test

The Full Moon mattress has a strong smell upon the initial unboxing. It notably filled our studio with off-gassing odors for a full day. However, the smell does start to rapidly dissipate.

Initial Smell Strength

Strong

Off-Gassing Period

5 days

While the smell remained strong for several days, by the 5th day the smell had fully dissipated.

On average, we see mattresses smell for 2.79 days. While the Full Moon mattress is certainly longer than the average, the smell isn’t abnormally strong and doesn’t linger abnormally long.

9.8

Company

The Full Moon mattress is manufactured by GoodMorning.com, the same company that manufactures the Novosbed, Doulglas, and Logan & Cove.

As a company, GoodMorning.com offers a 120-night trial period and a 15-year warranty on the Full Moon mattress.

Company Factor
Trial Period120 nights
Warranty15 years
ShippingFree
ReturnsFree
Country of OriginUSA

The head office for the company is located in Canada, but all of their mattresses sold for the US are also manufactured in the US—Pennsylvania.

Full Moon does have a 30-night “Break-In Period”, which is pretty standard. This is a window of time between night 1 and night 30 where you cannot request a return. During this time, your body begins to adjust to the mattress.

The way you feel about a new mattress can change quickly so try and give it time…whether you go with Full Moon or any other mattress for that matter.

How firm is the Full Moon?

The Full Moon mattress is around a 6 out of 10, where 10 is the most firm. This is right in the middle of the firmness scale and about where we want to see for mediums.

firmness - 6 out of 10 - medium

At this firmness level, the Full Moon should be firm enough for some light to moderate back or stomach sleepers, but also soft enough for those lightweight side sleepers.

Support & Sleeping Positions

Much like pressure relief, support on the Full Moon mattress is mixed. This is simply due to the overall thickness of the mattress and the thinness of the comfort layer.

An 8” mattress just isn’t going to be thick enough for all weights, body types, and sleeping positions. Likewise, a 2.0” thick comfort layer isn’t going to cut it for all sleepers either.

You can see these results reflected in the table below.

Sleeper WeightStomach SleepersSide SleepersBack Sleepers
Under 150 lbs.YesYesYes
150-250 lbs.Yes YesYes
250-300 lbs.YesYesYes

Based on the material construction and design of the Full Moon mattress it is best able to support lighter-weight sleepers and those that sleep on their back or stomach.

Side sleepers, moderate weight, and heavier weight sleepers all put more pressure on the mattress. That extra pressure requires a thicker profile and thicker comfort layer.

The Full Moon mattress is a simple foam mattress with a thinner 8″ profile and a mid-range firmness of 6 out of 10 on the firmness scale.

The Cover

The cover of the Full Moon mattress is a blend of polyester and viscose knit. It is soft and breathable, with a stretchy feel to it.

Thre are no handles or reinforced materials used on the sides of the mattress, but this also helps to keep the cost down.

The Comfort Layer

Thickness: 2.0″

The comfort layer on the Full Moon mattress is only 2.0″ thick, which is a less than ideal. Or in other cases where only a 2.0″ comfort layer is used, there is usually a secondary transitional foam layer to provide better pressure relief from the support foam below.

The Support Layer

Thickness: 6.0″

The bottom layer of the Full Moon mattress is a simple 6.0″ layer of support foam. This support foam is more high-density compared to the poly foam above.

For support foam, I would say that 6.0″ is sufficient. 6-8″ of support materials is typical.

How is the Full Moon Different?

Wondering how the Full Moon mattress is different from the competition? Well there’s basically one point to mention—an extremely low price.

#1. Budget Friendly

The Full Moon mattress was essentially designed as a super budget-friendly mattress. A queen mattress for under $500 is nearly unheard of in today’s market.
