Dual-sided sleep system Review

Dual-sided mattresses are two-stage sleeping systems. The mattress has two separate layers, one for infants and another for toddlers.

While regular crib mattresses are designed just for an infant or solely for a toddler, you can use a dual-sided crib mattress during both age stages.

Infant’s side of the crib mattress:

Is Moonlight Slumber Little Dreamer’s infant layer as good as a crib mattress made only for infants?

Yes, it is, and the same is with the toddler side.

Moonlight Slumber Little Dreamer crib mattress has one of the best dual-sided systems we have ever seen. Both layers meet all safety and quality expectations, and can easily compete with the best one-sided crib or toddler mattresses.

Everything is as it should be! While the infant layer is extra firm, made of, eco-friendly, plant-based, and high-density foam, a soft and plushy foam side is perfect for toddlers.

Note: Make sure you always set the crib mattress on the right side. Usually, you can flip it on the softer side around 9 months of baby’s age, but we recommend using it on the firmer side for as long as possible.

Sleeping on a firm surface is something babies are used to, so don’t rush. Why? Firmer mattresses are better for their development!

Moonlight Slumber Little Dreamer crib mattress specifications

  • Mattress size: 52″ long by 27,5″ wide
  • The thickness of the mattress: 5″
  • Mattress weight: 10 pounds
  • Age and weight limits: The core of the mattress is from memory foam, so it regains its original shape easily. That’s why there is no weight limit for this particular crib mattress. Your child can use it until he outgrows it, and most likely your second child will be able to use it as well.

We were impressed by how light it is! Because it is made of foam, it is already lighter from innerspring mattresses, but it is lighter than most foam crib mattresses too.

Moonlight Slumber Little Dreamer crib mattress Specifications

The lightweight of the mattress is important. Accidents do happen, and they usually happen in the middle of the night. Getting the mattress out of the crib easily, easy cleaning, and changing the sheets, is something you will like for sure!

Firmness for your baby’s health and lightweight for easy sheet’ changing is the best combination you can wish for a crib mattress.

Moonlight Slumber Little Dreamer crib mattress review breakdown

Although all Moonlight Slumber products go through extensive internal and external testing, we’ve tested its features anyway.

Your infant will spend most of the time sleeping, so he will use the crib a lot. That is why the safety of the crib and crib mattress is one of the most important things you should consider.


If the crib mattress is not firm enough, it is not safe! The safest sleeping position for your infant is on his back. If the mattress is not firm enough, he can turn his head or the whole body and doesn’t have the strength to turn it back. A soft sleeping foundation will conform to the shape of your baby’s face, which increases the risk of suffocation and SIDS (Sudden infant death syndrome).

Although the mattress went through rigorous firmness testing, we wanted to check it up too.

We’ve used a simple test, which you can do by yourself too.

Press on the mattress with one hand. If the mattress holds firm and spring back in place quickly, it is firm enough.

Fitting in the crib:

Sizes of the cribs and crib mattresses are standardized by the federal government, so in theory, all standard size mattresses fit in all full-size cribs.

Full-size crib mattresses must be at least 27 1/4 inches by 51 5/8 inches and no more than 6 inches thick. As you can see, the dimensions of Moonlight Slumber Little Dreamer crib mattress corresponds to the prescribed requirements!

Due to different crib frames, there may be minor deviations, so always check the inner dimensions of your crib and the size of the mattress. It must fit snuggle!

We try it in our Babyletto Hudson 3-in-1 convertible crib, and it fits perfectly.

A home test for fitting is very easy. Place your finger between the edge of the mattress and the crib frame. There shouldn’t be room for more than two fingers!

Is Moonlight Slumber Little Dreamer crib mattress comfort?

Because it is from memory foam, not innerspring, the Moonlight Slumber Little Dreamer crib mattress provides comfort to infants and toddlers.

Of course, for an infant side, safety is more important than comfort. So, the mattress is very firm on that side, but that is how it should be!

If it is too firm for you, it is safe for the baby! If a baby is tired, she will fall asleep just about everywhere anyway.

The toddler side had tested my almost three years old daughter, and she feels comfortable with it. It is just enough soft and plushy to sleep comfortably, but still with great support.

Mattress’s support:

Does it offer good support?

Yes, it does!

Even though the crib mattress has a dual-sided sleeping system, both sides give the proper support to your child. Just don’t forget to turn it on the right side!

Venting and heat regulation review:

A breathable mattress enables a good internal air circulation, which creates a climate that can cool or warm baby, depending on the environment.

Although the mattress doesn’t have visible venting holes on the sides, the special air channels in the foam enhance circulation, similar to innerspring mattresses where space between coils creates natural breathability

Heat retention test shows us how long it takes for a mattress to cool down from 130 to 98 degrees, which is average body temperature.

Moonlight Slumber Little Dreamer crib mattress cooled down in approximately 20 seconds, which is a good result, and proves that the child won’t overheat because of the mattress.

Corners and seams:

Corners of crib mattresses can be in two different shapes, square or rounded.

The appropriate shape of the corners depends on the crib model, but generally, square corners are a better choice.

As far as safety is concerned, there are no differences. The problem with rounded corners usually occurs because of the little gaps on crib’s edges that can catch pacifiers and other baby stuff. Also, sheets stay firmer on square edges.

Seams on Moonlight Slumber Little Dreamer crib mattress are dropped to the sides and sawn flat. That makes sheet changing and cleaning very easy. We like how tight sewn are seams, which contributes to waterproofing, the bed bug, and dust mite resistance, and prevents forming the odor.

The bounce:

The crib mattress must have a small, but not excessive bounce. Without a little bounce, the mattress would be hard as a rock. On the other hand, too much bounce prevents good sleep.

A Moonlight Slumber Little Dreamer crib mattress has just enough bounce for comfortable sleep and at the same time cannot be useful as a trampoline. Believe me a bouncing mattress, quickly becomes a trampoline for your cheerful toddler.


The mattress is extremely durable. If you handle it with caution, clean it as prescribed, and store it properly, you can use it more than just with one child.


Because the mattress is waterproof, liquids and stains stay on the surface. That makes the cleaning incredibly easy. Everything you need to do is wiping it with damp sponge or cloth, and you are done.

Note: Avoid cleaning with harsh cleaners, antibacterial, or diaper wipes. They contain additives that can eventually break down the waterproof surface of the crib mattress.

Moonlight Slumber Little Dreamer crib mattress safety

All Moonlight Slumber products go through rigorous testing procedures, to evaluate durability, safety, performance, and quality. The foam and all mattress’ components are third-party tested!

Moonlight Slumber Little Dreamer crib mattress meets or even exceeds all required safety standards. It is GREENGUARD and CertiPUR certified, which means that it is non-toxic. It is PVC, phthalate, lead, antimony, and vinyl free. The certificate also ensures that this is a non-indoor air polluting product, as it has a low impact on indoor air due to low VOC (volatile organic compounds).

The verdict

Moonlight Slumber Little Dreamer crib mattress is one of the best, if not the best dual-sided crib mattress on the market.

It offers firm support to your baby and a comfortable side for your toddler. Besides that, it is an eco-friendly and safe choice for your child. It meets all required safety standards, including dimensions for a perfect fit into a full-size crib.

It is not the cheapest choice, but far from the most expensive crib mattresses on the market. After our review, we are sure the Moonlight Slumber Little Dreamer crib mattress is worth your money, and you won’t be disappointed with your purchase!
