Finally found the perfect mattress!
As first time parents, we spent a lot of time researching every single product a parent might buy for their new baby. One of the toughest products for us to decide upon was the best mattress for our soon to be born baby boy. So many differing opinions on the necessary firmness, the best materials, foam vs spring, etc. We spent weeks struggling with this decision. After all, apart from maybe the choice of car seat, this is probably the second most important product category in terms of infant and toddler safety. I read through countless hundreds of reviews, spent time examining and measuring dozens of different mattresses in stores. But with so much conflicting information, it was still hard to make a decision. I really wanted to go with the Colgate Classica I, one of the more popular choices at the moment and one of the recommendations in the book Baby Bargains, an excellent guide for parents-to-be. However, there are lots of conflicting reviews as to whether the Classica is actually TOO firm. After testing it out in person, I happen to agree with this. The Classica is the firmest mattress I found anywhere by leaps and bounds, to the point where I felt sure that it would be uncomfortably hard. After giving up on that idea, I found this Moonlight Slumber Little Dreamer to be my next choice. I liked the idea of a company founded with the sole focus of creating the best possible crib mattress. Furthermore, it has the added benefits of being made of top quality, eco-friendly materials. No worries about chemicals or low grade materials, as this product is built and designed right here in the United States out of medical grade foam. We wanted foam over spring, as foam is significantly lighter in weight, which aids in those late night sheet changes. The dual sided densities are an excellent feature. To me, the firmest side feels like the absolute perfect level of firmness for a newborn/infant. Its very firm to the point where it feels certain to be safe, but with just the slightest bit of give to feel like it will still be somewhat comfortable. The slightly less firm side is still plenty firm, but with a little extra give for when your baby gets older. I also love the fact that the mattress is side stitched. This is a feature that never would have even crossed my mind when I first started looking. Instead of the standard construction where the seems of the mattress are bonded around the top edges of the mattress, the seams on the Little Dreamer are around the middle of the sides, one long continuous seam around the entire circumference, bonded together in a way where they are almost completely flat. This means if something spills on the cover, or if the baby has an accident, there are no crevices for anything to get trapped, and no space for mold to grow. The cover is also water resistant so nothing gets soaked into the mattress. Also, for anyone looking, we are using this mattress in the Babyletto Hudson crib, and it is a perfect snug fit. The corners are very square and it perfectly fits our crib, no unsafe gaps. We love the crib too, apart from one issue with a piece that was drilled incorrectly (replaced quickly by Amazon) it is absolutely wonderful. You can read my review about it on the product page. I realize there are many cheaper options out there, but this is one product where I feel justified in spending a little extra to get something as high quality as this mattress. Buy it and never look back, you won't regret it.

We looked at many beds and decided to buy this. The quality and hardness are very good, it was perfect for our bed and we liked it very much.

Worth the extra money
The best mattress! I have the mini crib size and as I was moving my son into his full size crib, I thought I’d save some money and get a big name mattress for half the cost. What a mistake - this has excellent firmness for a baby, it’s completely silent - no rustling when laying down or turning. Zero smell and great support. Well worth the investment! It expands right before your eyes and takes shape quickly. Any wrinkles smooth out in time. Very happy with this!

It’s perfect!
I did a lot of research before buying this mattress, especially comparing it to the breathability mattresses that seem popular now. My research confirms that the breathability mattresses are not any safer and don’t protect against SIDS any better than a firm mattress with tight fitting sheets and, of course, no blankets, pillows or bumpers. Plus, you obviously can’t use a mattress cover or any waterproof padding with the breathability mattresses. Instead, when baby messes, as they always do, you have to take the mattress out, unzip the breathability padding that covers the entire mattress, and then wash the mattress in the tub or shower. Not for me! Too much work for no gain. The Moonlight mattress is very firm on the infant side and a little softer on the toddler side. Both sides are very clearly marked. My baby sleeps soundly on this. I use a mattress cover on it. I’m very petite and have no trouble changing the sheet or mattress pad with no additional help. The price is also very reasonable. When I found that both Wirecutter and Forbes rated this as the best overall mattress, I was sold. You should be too!

Won’t regret this mattress
I highly recommend this mattress. Both of our babies slept on this mattress, and now our older toddler graduated to the full mattress. It’s comfortable, they sleep well and the best part is how easily it cleans! No stains or smells. Looks brand new still after almost 4 years and some accidents.

Firm and comfort
I am really happy with my purchase this mattress fits perfectly inside a playpen for extra firm comfort. There were no open gaps in the corners. The mattress came in a plastic bag rolled up and it didn't take long to come to its position.

Well it is very firm..
I searched everywhere, looked at a million reviews.. and FINALLY decided to order this mattress for my 2 month old baby. I figured that the reviews with 1 and 2 stars could just be the few that got unlucky or just like to complain?? Haha. How picky can an infant be? Well turns out she obviously prefers to be cuddling in my bed, in my arms. With that being said it does take awhile for her to fall asleep on the mattress, it’s VERY FIRM, but that’s what is recommended. I think as long as I get her used to her new crib she will learn to sleep there without an issue in the future. There’s an infant side and a toddler side clearly labeled. No weird smells out of the box, it was ready to be used so that was a plus. I did think it would be thicker for some reason but no big deal. So far no issues, seems like a good purchase!

AMAZING Customer Service and Mattress
I have to share my story with everyone as I can not say how amazing Moonlight Slumber is as a product and as a company. As a product, they are so highly reviewed, everything is natrual and made to cater to today's world of safe and high quality materials for the mattress. That is what drew us their product versus the competition. But like all expecting parents, nothing is harder than researching the perfect mattress for your baby. We went through SO MANY reviews and possibilities and thought we found it. And then the unthinkable happened, we bought a crib, got the mattress and the mattress was too short! They say it HAS to be a tight fit. And we found out it wasn't the mattress (we looked at so many different specs) and the crib was 53" long! No mattress fitted it. We looked and looked for a new mattress and finally we ended up on the Moonlight Slumber website and saw they make "custom sizes". We immediately e-mailed them willing (and expecting) to pay $$$$ and having to go through the hassle of returning the old one to Amazon - but we didn't want a subpar awful replacement. Art and Christy at Moonlight Slumber were incredible. They asked me the exact specifications of our stupid crib (Walmart - Brookline, looks beautiful, great price but this 53" thing is not good!!) and within a week, made us a BRAND NEW CUSTOM size mattress, asked for my address and shipped it UPS. Not only that but they PREPAID for a return label! And extra thank you as we were on vacation and missed the shipment and it got returned and they sent it back again at no cost. Just incredible, nice, amazing and saved my wife and I from having one of those frustrating arguments about baby furniture (which I am sure we will have more of). And with all the money parents spend on their baby and frustrations they go through - this was a breath of fresh air and so unexpected kindness that the world has to know. Thank you again! We are grateful. Tony and Joanne 30 weeks pregnant
