Crib mattresses come in all forms, including organic, non-toxic, ultra-supportive … so, which one should you choose? And most importantly, which are the safest baby mattresses? Like everything you purchase for your baby, you’re gonna be doing some intense research, especially when it comes to finding the best crib mattresses. And there’s bound to be some headaches (and more questions) to follow. Which baby crib should you go with? Which bed rails work best? Should you buy disposable or reusable cloth diapers? How many swaddles or sleep sacks does one infant need? And just as you’re ticking off every essential in your registry, the one thing you realize is missing is the crib mattress. This is a big-ticket item as far as commitment (you’ll have it for years) and price (you don’t have to spend a lot, but the pricing really varies).

Buying the best crib mattress for your baby is getting harder and harder as more information comes out about how harmful traditional mattresses can be. There’s so much info out there about organic versus non-organic, and latex fibers versus rubber or cotton. It’s enough to make a busy and already exhausted parent’s head spin.

What type of mattress is best for a baby crib?

Rachel Mitchell, the founder of My Sweet Sleeper and a certified Pediatric & Maternity Sleep Consultant, helps clarify the big concerns including what exactly you’re looking for.

“Crib mattresses should always be firm to provide the safest surface for babies,” Mitchell begins. “We also want crib mattresses to be durable to withstand the wear and tear they might receive over the years. Ideally, you are able to use the same mattress with your baby in the newborn stage through toddlerhood and maybe even afterward, and as children get older they are harder on the mattress.”

Mitchell adds, “We also know that children can have accidents and soak through the sheets, so I definitely recommend investing in a waterproof mattress.” Of course, a crib mattress cover is another smart way to protect your investment.

Jean Moorjani, MD, FAAP, and a board-certified pediatrician at Arnold Palmer Hospital for Children, notes that whatever you choose, a good fit for your particular crib is key. “Even though it may seem like cribs and crib mattresses are all the same standard size, you want to select a crib mattress that fits appropriately in your chosen crib. Make sure that your crib mattress fits snugly in your crib without any extra spaces or gaps. Extra space might let your baby’s arm, leg, or head accidentally become trapped. Also, make sure that the crib sheets fit snugly so they do not slip off and potentially create a suffocating hazard for your baby.”

Essentially, you’re looking for something firm, thick, durable, waterproof, and the perfect size.  It sounds like a lot, but trust us Mama, it’s out there — and it’s organic too! Mitchell’s recommendations include brands such as Avocado Mattress and Newton Baby (which you can find below!)

What is a standard-size crib mattress?

Standard crib mattresses are about 28 by 52 inches, but there can be small variations in both “standard-size” cribs and crib mattresses that can ultimately impact safety. That’s why it’s always best to check the dimensions of your crib before purchasing a crib mattress, then double-check the fit before Baby sleeps on it.

Is a toddler mattress the same as a crib mattress?

Many crib mattresses are dual-sided, with one side being for infants, one side for toddlers. The major difference is the firmness; the infant side is extra firm to ensure safety and reduce the risk of accidental suffocation. Dual-sided mattresses tend to be more expensive, but they’ll last you much longer because your child can sleep on it for several years.

We’re not here to cause you any more headaches, which is why we did all the work and research in narrowing down the top crib mattresses for you. Organic, non-toxic, foamless, PVC- and phthalate-free — no matter what specific certification, ingredient, or material you’re looking for. You and your baby can rest easy knowing every mattress on our list is non-toxic and free of harmful chemicals. And even better, many of these mattresses have a dual-side design so you can invest in one that will last you from infancy through the toddler years.

One major decision— and worry— off the list! (And yes, you CAN still add it to your registry.)

Making sure our mattress and our little guys mattress is free from chemicals was extremely important to us. When the mattress arrived it was packaged in plastic and then placed in a box. It’s labeled so you know which side to use, toddler or infant. You can definitely tell which side is the infant side due to extra firmness. What we liked about this mattress is the moment we took it out of the plastic there was absolutely no smell. The mattress is super easy to clean, we still use a mattress protector just for added protection. Also, we liked the fact the mattress is very lightweight allowing my 5ft tall wife the ability to change sheets easily.”
