Buying the best crib mattress for your baby may not seem like an exciting task, but it is still an important one. Your little one will spend many, many hours in his or her crib (an average of 18 hours per day), and it is up to you to make the experience as comfortable as possible. For the most part, when looking over which mattress to buy, there are two main things to keep in mind: fit and firmness.
Before we get into the nitty-gritty details of what to look for in a crib mattress I am going to highlight the best-rated crib mattresses available in each category.
Our Best Crib Mattresses of 2020
*5 Star Rating: this is based on the percentage of consumers who rate the mattresses 10/10.
Top Rated: My First Mattress Premium Memory Foam Crib Mattress
The ‘My First Mattress’ memory foam crib mattress ranks number one on the list for several reasons. Consumers who purchase it rate it highly for many reasons. Unlike mattresses made with other materials, this one is perfectly silent. It makes no noise as your baby moves, allowing him or her to sleep peacefully – and quietly – throughout the night. The extra firm high-density foam provides all of the softness your little one needs to feel comfortable, but it is firm enough to meet safety standards at the same time. It is hypoallergenic, mite-proof, and free of potentially dangerous phthalates found in many other mattresses. It comes with a 100% polyester velour cover that is completely removable and machine washable, and thanks to its squared-off corners, it fits nicely into most toddler bed frames as your little one grows.
Best Organic: Naturepedic No Compromise Organic Crib Mattress
For those parents who are concerned about products made from environmentally-friendly and safe materials, the Naturepedic No Compromise organic crib mattress is a no-brainer. It is made with 100% organic cotton and it offers you the two-stage dual firmness that ensures that it can grow with your baby right into toddlerhood. The surface is wipe clean and waterproof, which makes things easier on busy parents and caregivers. The fabric and filling are certified organic, and the mattress contains 150 coils plus edge support to help extend its longevity right through the toddler years. Naturepedic meets the most stringent Greenguard certifications for eliminating chemical emissions, too. If safety and healthy are at the forefront of your mind when shopping for a crib mattress, you cannot go wrong with the Naturepedic No Compromise.
Best Memory Foam & Best Dual Foam: Moonlight Slumber Little Dreamer® Dual Firmness All Foam Crib Mattress
Dual firmness is an important consideration for many parents. As an infant, your baby needs an extra firm sleeping surface for safety, but as a toddler, a little extra softness can help your little one sleep better throughout the night. The Moonlight Slumber Little Dreamer dual firmness all foam crib mattress is one of the best buys for the money in the dual firmness category. It is free from dangerous vinyl, polyethylene, phthalates, and PVC, and it comes encased in a durable nylon cover that is waterproof and easy to clean. It offers extra high-density foam on the infant side, but when you flip it over, the toddler side has traditional high-density foam for extra softness. Despite its budget-friendly price, this is still the safest mattress in its class.
Best Natural Foam: Sealy Soybean Foam-Core Crib Mattress
If you want to purchase a foam crib mattress for your baby, but you prefer all-natural materials, look no further than the Sealy Soybean Foam-Core mattress. Sealy was the first company in the industry to utilize safe and renewable soybeans to craft a special foam that is firm enough for infants, yet still plush enough for toddlers. The mattress contains no harsh chemicals, including often toxic chemical fire retardants. It comes wrapped in a beautifully embossed cover that protects the inner foam from liquids and allergens. What’s more, the soybean foam is more durable than conventional foam. Parents who dread lifting the mattress to change baby’s sheets will be glad to know that this is one of the lightest crib mattresses on the market, and Sealy offers a lifetime warranty on materials and workmanship.
Best Cheap Crib Mattress: Safety 1st Heavenly Dreams White Crib Mattress
Finally, if you are shopping for a budget mattress, the Safety 1st Heavenly Dreams mattress is always a great choice. It offers you the most features and safety for the price, including a high-density foam core to provide all of the support your precious bundle needs. The sleeping surface is completely lead and phthalate free, and it meets or exceeds federal flammability standards without the use of dangerous chemicals. The cover resists tears, blocks water, and resists odors over time, making it an excellent value dollar-for-dollar.
The Size of the Crib Mattress
Crib mattress size is important because in order to keep your baby safe, you need to make sure that there are no gaps between the mattress and the crib at the top, the bottom, and both sides. These gaps are potential safety hazards. The federal government actually determines the standard crib mattress size and says that, at a minimum, a crib mattress must be between 27 5/8″ to 28 5/8″ wide & 51 3/4″ to 53″ in length and no thicker than 6”. Today’s cribs are also subject to regulation, but they have a bit of tolerance in order to accommodate mattresses without gaps.
Crib Mattress Firmness
Firmness is also an important consideration when choosing a top rated crib mattress. The American Academy of Pediatrics recommends that babies sleep on their backs on a firm crib mattress. A soft mattress can actually conform to the baby’s head, as well as his or her face as he or she learns to roll over and cause suffocation or Sudden Infant Death Syndrome (SIDS). A firm mattress, then, is a must-have. Many parents choose innerspring mattresses for this reason, but the truth is that a memory foam crib mattress is just as firm. In fact, memory foam is usually easier to work with and safer as your child grows older.
The Benefits of a Memory Foam Crib Mattress
A memory foam crib mattress is often the absolute best choice for several reasons. First, it is lightweight, which makes changing sheets – which you will likely do quite often – much, much simpler. What’s more, memory foam crib mattresses are often very firm at the same time, so you do not have to sacrifice firmness for convenience. Finally, experts recommend that parents swap out innerspring mattresses for foam mattresses at about the time a baby begins to pull to a stand. An innerspring mattress can act as a trampoline and cause some safety concerns for your little one. To ease your budget, it is best to choose memory foam from the start.

Dream On Me manufactures a number of standard and portable crib mattresses from which you can choose. One of their most popular products is the 3” Dream On Me portable crib mattress, which is perfect for travel.

Sealy is one of the world’s most popular mattress manufacturers, and they offer several options for newborns, infants, 
and toddlers.

A popular option among parents who prefer all-natural materials, the soybean foam core offers a firm, yet comfortable sleeping surface. It boasts an airflow pocket on the side to keep the mattress clean and fresh, and its squared-off corners provide a super snug fit into your standard-sized crib.
#2 – Sealy Natural Rest review
This mattress features 204 durable innerspring coils and firm hypoallergenic cushioning. It offers plenty of firmness for infants, yet the steel border rods help the edges of the mattress hold up as your toddler grows. It has a waterproof cover that resists stains, moisture, and mildew.

Kolcraft Crib Mattresses
The Kolcraft Baby Dri crib mattress is another inexpensive purchase that features 80 interwoven innersprings for firm support and durability. It comes wrapped in a thick hypoallergenic cover that provides a barrier against liquids, and it is easily cleaned with nothing more than mild soap and water. The natural airflow pocket helps keep the mattress fresh and odor-free without the need for metal vents, and despite the low price, it also features a 10-year warranty on workmanship and materials directly from the manufacturer.
As you can see, the possibilities are endless when it comes to choosing a baby crib mattress. The two most important features are firmness and fit, but you can find several mattresses that are designed to grow right along with your baby and last you for years to come.
Do You Need a Crib Mattress Cover?
Any time you purchase a memory foam mattress for a baby or child, it is a great idea to also purchase a crib mattress cover to protect it, otherwise known as crib mattress pads. Memory foam is very porous and lightweight; these features provide the comfort and proper sleeping posture. Unfortunately, the same features can lead to a mess if a cover is not used. Look for a zippered crib mattress cover that fits snugly over the mattress, and make sure that the zipper is at the bottom or the side of the mattress when installing in the crib. For the absolute best results, find a cover that is completely waterproof and hypo-allergenic, as this will serve your baby well for a very long time to come.

What about a Memory Foam Crib Mattress Topper?
Many retailers sell memory foam crib mattress toppers, but the truth is that it is much safer to simply purchase a 6” thick memory foam mattress. Even the best crib mattress pad is usually quite thin – up to 2” – and can sometimes pose safety risks when added to a standard crib mattress. However, if you travel frequently and use a portable crib, you can find thicker and firmer memory foam crib mattress toppers to suit your needs and provide your baby with comfort.
