View larger View larger View larger Crib Mattress Buying Guide A crib mattress is an essential purchase for your baby. One of the most important things caregivers can do for newborns is to provide them with a safe sleeping environment. To help reduce the risk of suffocation, SIDS (Sudden Infant Death Syndrome) or SUID (Sudden Unexpected Infant Death), a properly assembled crib and proper fitting crib mattress should be used without toys, blankets, pillows or corded electronics in or near an infant’s sleeping space. Choosing the right crib mattress for your baby can require a bit of research as there are many to choose from. Purchasing a new crib mattress is best instead of second hand. You don’t know how the previous owner used or stored the product. Plus crib mattresses available today are made to the latest standards. Crib mattresses are designed to fit inside USA standard size cribs and toddler beds. Each crib mattress will fit inside a 52” x 28” crib (with plus or minus dimensions) and are no thicker than 6” measured from seam to seam. Find information about crib fit and measuring the inside dimensions of your crib to help ensure a snug fit for your crib mattress. You can purchase two-stage models which offer a firmer side for infants and a softer side for toddlers. Focus on the 4 C’s of a Crib Mattress to help you decide: Core, Cushioning, Cover and Certifications Core Types Innerspring Crib Mattresses Innerspring coils are made of steel and are heat-tempered, which means the coils will bounce back into shape easily. For the best type of innersprings, look for a higher coil count, which means the coils are closer together, helping to create a firmer surface overall. Upgraded innerspring models include border wire or border rods, which is thick steel wrapped around the edges to keep them supported. Additional features include weight distribution systems, cross frames and corner and side protectors, like pylons, which help to make the core more durable, firmer and supportive. The great thing about steel coil innersprings is that they last a lifetime and you can find high-quality innerspring coils from affordable models to premium crib mattresses. Coil crib mattresses will weigh between 10 and 20 pounds depending on the interior core and cushioning. Anything much heavier than this is the exception, not the norm, for crib mattresses, as you want to easily be able to lift and change crib sheets. Foam Crib Mattresses A high-density polyurethane foam core that is at least 1.5 pounds per cubic foot. The higher the number of pounds per cubic foot, the firmer the core. Premium foam models include soybean enhanced foam cores made with CertiPUR-US Certified foam, which have been tested for durability and chemicals. Some crib mattresses use a polyester material that are not considered high-density, but are more affordable models for short term use. New ultra-firm and ultra-lightweight models include polyethylene foam, which can weight around 5 pounds. Quality high-density foam crib mattresses typically weigh between 8 and 13 pounds making it easier to lift and change crib sheets and crib mattress pads. Cushioning Types Cushioning inside crib mattresses offer your child comfort, firmness and some can even offer a cooling effect! Hypoallergenic cushioning like polyester, cotton, organic cotton, memory foam, and new innovations like soybean cool gel foam are popular materials used inside baby’s crib mattresses. These materials are more popular and preferred over heavy coconut coir or gray ortho pads. One thing to note about organic cotton is that organic materials or covers can be used, although the entire crib mattress is not made of organic material. Cover Types A waterproof and easy-clean crib mattress surface is the most important thing to look for. Despite added protection from crib mattress pads, you want to be sure that the mattress cover and binding is waterproof to avoid liquids from seeping inside the crib mattress, which can cause mold and bacteria build up. Vinyl laminate covers are the most popular because of their durability and easy-clean surfaces that don’t allow leaks to seep through at all. If you have any concerns about vinyl covers just look for the GREENGUARD Certification, which means the crib mattress has been tested for chemical emissions and is safe for use with infants. Upgraded crib mattresses can include a hospital-grade antibacterial cover to help keep germs from spreading on a crib mattress surface. Many premium crib mattress covers include woven fabrics and soft cotton cloth. These fabrics are treated with safe waterproofing and stain-resistant materials while giving your child a softer, more breathable material on a premium crib mattress. Certifications The key certification to look for is GREENGUARD Gold Certified crib mattresses, formerly known as GREENGUARD Children & Schools Certification, which measures the chemical emissions from the mattress. If a crib mattress has been certified, this means an outside laboratory tested it to see whether it poses any air-quality risk to your baby. The materials including the core, cushioning and cover are tested. CertiPur-US is a seal found on high-density polyurethane foam sourced from companies who comply with a high-quality foam without hazardous materials.

This is NOT a newborn or infant mattress. Although it can be used as such. I would not recommend it. Firstly, because it’s quite firm. Not sleeping on bricks firm, but in my opinion too firm for a child under 12 months. Overall, the mattress has superb quality. Far exceeding expectations. It comes in white cover-film, like an adult mattress. Also, it may be too long for many standard cribs, and too high. This is PERFECT, for a TODDLER BED. It’s thick and sturdy, like an adult bed. I purchase this along with the Orbelle, toddler bed, for my daughter. Perfect in every way, looks like a grown up bed. It reminds me of the beds at POTTERY BARN, which is essentially the same size as this mattress,just 5x the price. In terms of value and quality, I don’t see a better value out there. This is a great Toddler mattress, and should be a must have on any Mom’s list.

Great Mattress!

I was a bit skeptical at first since this mattress is so cheap compared to some of the other ones at other stores. The mattress is firm and has the waterproof material all around which is nice. The mattress fit PERFECTLY in my babi italia eastside crib. There is no gaps or spaces or anything. I am very pleased with my purchase!

Kolcraft Pure Sleep Therapeutic 150 Crib Mattress

This mattress came super fast-even before the crib, which I ordered first. The mattress was very easy to get out of the box, which was the perfect size for the mattress. Once the crib arrived, which is a standard sized crib (Davinci Jenny Lind crib), I put the mattress in, and it was a perfect fit. No big gaps. The only thing I would mention is that the plastic wrap around the mattress was very dirty-as in, I got black fingers from handling it. Don’t let it touch your baby bedding! Other than that, you can’t beat the price and quailty of this mattress.

Lidia Bloomfield, NJ

great matress for a great price

Before i ordered this matress i read a lot of reviews about a lot of products that are available on the market. Since the price also mattered i decided to go with this product, taking in consideration that it had good reviews by previous customers.oh im so glad i choosed this one. After seeing and touching couple of matresses in local stores i can honestly say that the quality of this one is way better. it fits the crib perfectly, its firm anf u can feel the .metal construction inside.I love this productAlso came on time and well packaed.Im very satisfied with this putchase

Do not purchase this mattress. It is way too soft and provides no support. My daughter couldn’t even sit up on it and would fall to her side. It was like watching her trying to sit up right on a water bed. It would also depress, than poof back up (like an air mattress).

Hazel South Barre, MA

🙂 and :/

So, here’s what I found. It doesn’t really fit my crib, but it’s been tough finding a good mattress with the qualities that this has. The price is amazing compared to target’s mattresses that do not have the same qualities that this one does, and yes there are gaps in the crib, but I will work on that. I want nothing but the best for my 3 month old and this seemed a good deal.I have my doubts, and I will update as I notice either bad or good changes when my child starts rolling around in his crib. GOOD LUCK!! IT’S hard work this parenting, but we do the best we can. 🙂

comfortablr for my little one

First, sizing is dead on. Says it is a standard size and it fit my crib which was also standard size (aLaJobi Nursery 101 Coconcord Classic Crib, Cherry). No gaps between the crib and mattress to worry about.Next, its fairly thick for a baby mattress, I know some are only a few inches thick. Makes me glad because I can see this lasting awhile.Also, it is already a waterproof mattress. You don’t need to purchase a special mattress cover for this.My son is quick to let us know if he’s uncomfortable, and his first time in the crib he just laid there and smiled. Definitely a winning mattress for me, and I guess I caught it on sale, but it was priced around $56. Best part was that with Amazon Mom, I got free two-day shipping and didn’t have to pay extra for it being oversized. A great deal for a great product.

Katie Cameron, WV

A little too soft.

For an infant, I don’t think this mattress is firm enough. I bought it for our baby-to-be, but ended up using it for our toddler’s bed instead.

Dianne North Chicago, IL

No complaints

My daughter hasn’t been able to sleep on this mattress yet, but I already like it because it’s so very light. Her crib mattress was a hand-me-down, and it’s so very heavy, which makes it difficult to change the sheets. But this mattress, for her toddler bed, is so light that it’s a breeze to change sheets!

Alexandra Stryker, OH

Ok Matress

It’s nothing special – it’s a firmer spring mattress. When I received it I laid it on the floor and laid on it to see what is was like and it wasn’t very comfortable for an average adult. As you can imagine I weigh far more than my new born so the springs were quick to say hello. I’m sure for a child of 10-30lbs it’s not as bad, especially when lined with so many plush blankets but not something I would consider using for an older/larger child.

Brandi Linwood, MD

Yucky Smell!

I let this thing air out for over 2 weeks, and the vinyl smell was still overwhelming. I had to send it back. Plus, it "crunches" when your child is on it. Really disappointed given the good reviews. Will not buy a mattress online again. Went to B-r-us so I could smell test the mattresses first.

Margarita Camanche, IA

Junk- no support at all!

I purchased this product based on the good reviews on amazon (which are most often reliable). My son is just 3 months old and weighs about 12 lb. Within a week of using it, i noticed a huge depression where his head typically lies. This mattress obviously lacks support and I can see this being a safety issue for an infant. Take a look at the other reviewers who have rated this item as poor- they had identical complaints. Amazon is great and sent a courier service to pick this item up from my home for return. I’ve decided to go with the Moonlight Slumber Little Dreamer Dual Firmness All Foam Crib Mattress (~$180) based on the recommendation from the Baby Bargains Book. I’m purchasing this from amazon as well due to their excellent customer service. Fingers crossed!

Corrine Mack, CO

Good product

It is a perfect fit for my Graco Lauren crib. I like the thickness, it is firm, and waterproof. Good deal for $60!

Marta Centerville, WA

good quality mattress at a great price

This mattress arrived very quickly to my home only a few days after ordering. It is a nice firm mattress and will work great for my baby. It was a great price and is a quality product.

Nettie Tipton, OK

Good crib mattress

Mattress is firm, fits well in our crib. Some people had comments about a plastic odor, but I didn’t notice anything when we got it and I don’t notice anything now. I actually like it that it is a plastic-y casing, because if the baby has an accident I can wipe it down with a Lysol wipe and let it dry before putting a new sheet on it.

Cora Hampstead, NH

My daughter sleeps great.

I obviously haven’t slept on it, but my daughter’s favorite place to sleep and play is in her crib. She seems to think it’s quite comfortable!

Adriana North Creek, NY

Very satisfied with this crib mattress

This mattress fits my daughter’s crib perfectly. Very snug, leaves no gaps, but not too big that it has any issue fitting into the crib easily. Seems quite firm, as a baby’s mattress should be, yet still comfortable, and appears to be very well constructed. My daughter has been using this for 4 months now, and it looks as good as new. I see no reason to believe this mattress won’t last her for many years to come. The mattress came well wrapped in a thick plastic, and unlike other reviewers, the packaging was clean. I consider myself to be a picky mom, without feeling the need to purchase the most expensive items, and I consider this to be a high quality crib mattress for a very reasonable price. Would purchase this again.

Petra Coal Hill, AR

Great mattress!

We had a firmer more expensive mattress but after we replaced it to this my son loves his bed. It is a bit on the very bouncy side so when he stands up to walk it makes me nervous but I think to sleep on its excellent. He really just loves it.

Karla Price, MD

My sons seems to love it

My son is 10 weeks old and seems to love sleeping in his crib. The mattress is firm enough and fits in the crib nice and snug. A great mattress for an even greater price!

Kristy Hammon, OK

Nice mattress

I like this mattress and so does my baby. It is firm but not so firm that it feels like she’s sleeping on a brick. I did have to air it out for a couple months after we ordered it because it STANK of chemicals when it arrived. That is probably true of any mattress though so just leave time to air it out if you can. It’s great now though.

Janelle Suring, WI

Dent where baby sleeps after only 2 months!

I bought this for my newborn who was born in August. After only 2 months of her sleeping on it, there is a dent where she sleeps. This cannot be safe and I can’t imagine how a larger baby or toddler could use this mattress. There are many other reviews who say the same thing. I strongly encourage Amazon to remove this faulty product.

Emilia Echo, OR

Great for us

We have 2 and they are both great for us :). I have one for our 18 month old and one for our two month old 🙂

Rosalind Wauchula, FL

Good quality

This is a good quality mattress. It fits a crib or toddler bed. It seems to be quite comfortable and durable.

Dora Anthony, KS

Great mattress for the money!

I did a good amount of comparison shopping before buying a mattress for my daughters crib. Regardless of what any other reviews say, this mattress is well made and plenty firm for a little one. Fits the crib perfectly, and at a fraction of the price of other crib mattresses, I think it was a great choice!

Yvette Milford, MI

Great Mattress

This mattress is just the right firmness without feeling like a rock. With some fluffy chamois sheets from Pottery Barn Kids, EVEN I WANTED to cuddle up in the crib. It also fits snuggly in a standard crib, leaving no gas between the mattress and the rail.I’ve been using it with my son for 4 months and haven’t noticed any sagging in spots like some reviewers have said. Perhaps they don’t have a good support under the mattress?I purchased a protective mattress cover for peeing and spitting-up protection, so I can’t speak to its stain resistance. I got the Sealy Stain Protection Crib Mattress Pad. It fits perfectly and still allows the fluffy sheets to fit snuggly on!

Sharon Fredericksburg, PA

Fits Perfect

This fits perfectly in the Stork Craft Tuscany crib we bought on Amazon. It is also a good firmness, not rock hard but not floppy or soft.

Adriana Sycamore, OH


I am so glad I took a chance on this mattress. We were a little leary purchasing online without touching or feeling it but the reviews aided in my decision. My 19month old LOVES IT. She slept on it last night for the first time and slept ALL NIGHT. I am beyond thrilled. With her being able to sleep all night on it means mommy and daddy got some sleep. The recommended rock hard infant mattress that she had no longer suited her. its only been 1 night, so for now, i’m a happy camper and satisfied customer. the specs listed are just as it says. the mattress is not too hard or too soft – its just right. if your baby wakes up in the middle of the night 3-4 times per week, consider a softer mattress. It works!

Marcella Coronado, CA


I am very please with the construction of the mattress. It seems durable, firm, yet comfortable. It fit in the crib well without any weird, dangerous gaps. No chemical smells, and wasn’t dirty when it arrived.

Hattie Red Ash, VA


It is good for the price. You get what you pay for with mattresses. We plan on having it for a long time so I wish I had spent a little more for one that fits the crib better. Slight rounding where it meets the corners.

Florine Summerton, SC


I can’t even imagine purchasing a mattress that was not this brand. I love how soft the mattress is compared to most "crib" mattresses. The covering definitely assures that nothing will stain it or wet the actual bed. But I was stunned to know how truly hard some crib mattresses are. This is perfect, and after almost 4 months of sleeping exclusively in the crib, my daughter is extremely comfortable and the quality is great. I do suggest and recommend rotating it, i.e. flipping it over and turning it as well to help wear it more evenly. GREAT quality for the price!
