How is the Full Moon Different?

Compared to the average, the Full Moon performs slightly lower than average based on all 250 mattresses we’ve tested to date.

However, it is priced significantly lower than the average foam mattress as well. Considering the lower performance score, the Full Moon is an decent value mattress.

Advantages

Well there’s basically only one advantage to the Full Moon—an extremely low price. The Full Moon mattress was essentially designed as a super budget-friendly mattress. A queen mattress for under $500 is somewhat rare in today’s market.

As for motion transfer, our tests showed it was able to limit motion levels nearly 4 times better than the average mattress.

Additionally, the mattress off-gassing slightly quicker than average.

Neutral Factors

The mattress has low sinkage. Relative to the other mattresses we’ve tested, it has 22% less sinkage than average.

Bounce is also lower. The Full Moon has a bounce of 5.66″, which is a good deal lower than the average of 9.53″. Neither of these are bad by themselves, but you’ll want to prefer less sinkage and bounce to enjoy this particular mattress.

Disadvantages

The Full Moon unfortunately has a lot of areas that are just about or just under average performance. We measured higher edge compression in our sitting edge support test, for example. The factors that make up sex performance came together in a much lower score there too.

Overall, it’s a much thinner mattress and it really hurt its performance in most categories, but especially for pressure relief.

While it’s true that you give up some high-end materials and performance to get the low price, if you aren’t super picky on a mattress, this can still be a fantastic option for a solid budget pick.

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.

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.

• 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

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.

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 2.12”.

The level of sinkage is documented in the image below.

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

This is significantly better than the average motion transfer across all mattresses we’ve tested to date, which is 8.78 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.

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.

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.

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.

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

This is significantly lower than the average bounce height across all mattresses we’ve tested to date, which is 9.53”.

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.

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.

For a mattress that’s only 8.0” thick, that’s effectively a full material collapse. On average, we see 4.04” 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.

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.

To score sex performance we look at a number of different factors that all play a role in quality sex. The Full Moon has mediocre sex performance.

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

Sex Factor	Factor Weight	Score	Rating
Bounce	65%	6.0	Low
Edge Support	20%	6.3	Mediocre
Noise	5%	10	Minimal
Pressure Relief	5%	8.0	Good
Cooling	5%	8.0	Good

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.

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.

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.

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.

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.

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.

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

On average, we see mattresses smell for nearly 7 days. Altogether, the Full Moon mattress is certainly faster than the average, the smell isn’t abnormally strong and doesn’t linger abnormally long.

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.

The trial period is a bit lower than the average 173 nights that we’ve averaged over 240 mattresses tested to date. However, 15 years is a bit longer than the average 13-year warranty period, excluding the 25% of company that offer lifetime warranties.

Company Factor	Factor Weight	Score	Data
Trial Period	15%	8.0	120 nights
Warranty	10%	8.0	15 years
Shipping	5%	10	$0
Returns	20%	10	$0
Trust	50%	8.0	Good
Country of Origin	0%		USA

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.

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.

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.

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 Weight	Stomach Sleepers	Side Sleepers	Back Sleepers
Under 150 lbs.	Yes	Yes	Yes
150-250 lbs.	Maybe	No	Maybe
250-300 lbs.	No	No	No

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.

Design

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.

This mattress is a bit of an outlier compared to the size and materials of most other mattresses, but it also offers one benefit that other mattresses rarely beat—price.

Materials

There are only two simple layers on the Full Moon mattress. You can see a detailed breakdown of these two materials below.

• 2.0″ poly foam
• 6.0″ support foam

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.

The cover is mostly a neutral gray with a crisper white at the head and foot of the mattress. On the end of the mattress, there is also a navy accent bar with white stars.

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.

Product Evolution

The Full Moon mattress was launched in 2022 and it is new to the GoodMorning.com lineup. Since it’s new, there have been no design changes or product evolution to note.

As this mattress continues to age and evolve, we will be sure to update this section.
