What Makes a Crib Mattress Good?
Creating a safe and comfortable space in the crib ensures your baby will get great-quality sleep, which significantly aids their development. Choosing the best crib mattress for your baby’s crib is arguably the most important factor in creating such an environment.
A quality crib mattress should fit the crib perfectly and ideally be breathable, washable, and waterproof. However, above all, a good crib mattress should be firm. The firmness of the mattress is a critical factor in reducing the risk of Sudden Infant Death Syndrome (SIDS) and similar sleep-related infant deaths.
An appropriately firm crib mattress is typically made with inner springs or foam.
As the name suggests, innerspring crib mattresses contain metal springs surrounded by foam or polyester layers. Innerspring mattresses are usually more durable but are also among the most expensive crib mattresses on the market.
Foam mattresses are typically made of dense polyurethane foam or latex. Although a foam mattress costs less than an innerspring mattress, it can give off harmful chemicals unless it’s GREENGUARD Gold certified.
Parents looking for a highly breathable crib mattress should look into the latest “air core” products. These mattresses have a woven mattress core made from food-grade polymer, making them incredibly cool and breathable.

What to Consider When Looking for the Best Crib Mattress
Since safety and comfort are paramount, the task of purchasing a crib mattress warrants careful consideration. Here are the factors you should consider when researching the best crib mattress options.
Firmness is arguably the most essential consideration when purchasing a crib mattress. Babies inevitably roll over while they’re sleeping. If the mattress is too soft, they might suffocate. For this reason, you should only place your baby on a firm and flat sleeping surface. Of course, you shouldn’t go too overboard, either. The best crib mattresses should still allow your baby to sleep peacefully.
A crib mattress should fit so snugly inside the crib that you struggle with changing the crib sheet. For this reason, you should double-check the mattress size before ordering it. The standard crib size is around 28 by 52 inches, and a full-size crib mattress should match these dimensions. If the mattress is smaller, your baby might sink into the crib’s sides and potentially get stuck.
Of course, portable cribs are smaller, so they won’t fit standard crib mattresses. Generally speaking, mini cribs typically have a 24-by-38-inch crib frame and require mini crib mattresses.
Crib mattresses come in various materials, including cotton, wool, foam, and polyester. In general, there’s no right or wrong choice as long as you consider the material’s construction. The right crib mattress should be free of chemicals and toxins. So, when shopping for a mattress, look for designations like “non-toxic mattress,” “organic wool,” or “hypoallergenic materials.” This way, you’ll ensure the mattress doesn’t irritate your baby or cause allergic reactions.
If your baby runs hot, you should prioritize breathable materials. A breathable mattress will remain cool throughout the night, keeping your baby comfortable at all times.
Besides keeping your baby cool, a breathable mattress plays another crucial role. Namely, it will ensure your baby can still breathe even when flipped on its stomach. The mattress’ breathability depends on its material. So, the best crib mattresses will be made from lightweight and breathable materials, such as latex foam and hyperelastic polymer.
Most crib mattresses fall under two categories: single or dual-sided. A dual-sided crib mattress offers different firmness on each side. One side is firmer, making it safe for babies. The other side is slightly plush, serving as the perfect toddler bed mattress.
Parents-to-be on a budget should consider purchasing dual-side mattresses, as they double as toddler mattresses and can be used for several years.
As first-time parents will quickly learn, diapers aren’t always leak-proof. For this reason, they should look for waterproof crib mattresses or at least mattresses that come with a waterproof cover. These features become all the more important, considering that accidents aren’t the only thing to worry about. Your baby might also spit, drool, or vomit on the mattress.
Whatever happens, waterproof crib mattresses can be easily wiped down. If you go the waterproof mattress cover route, make sure it’s also made from non-toxic and organic materials.
Unfortunately, even some of the best crib mattresses are only partially washable. Those that are fully washable can be hosed down outdoors or cleaned in the shower. However, many mattress covers are machine-washable, so purchasing one for your mattress is highly recommended.
Have Peace of Mind During the Night Shift
With so many choices floating around the web, selecting the best crib mattress for your baby might seem daunting, especially if you’re a first-time parent. However, this vital task becomes significantly more manageable when you know what to pay attention to and how to approach the selection process.
Generally speaking, there’s no wrong choice, provided the mattress is firm enough to support your baby and contains no hazardous materials. Other features boil down to your budget and preferences.
The ultimate goal is to purchase a mattress you trust to keep your baby safe while you or your partner aren’t around.
