Sleeping safely and comfortably is important for everyone but even more so for babies, considering the majority of their first few months are spent snoozing in your arms and their cribs. According to the National Sleep Foundation, newborns up to 3-month-olds need between 14 and 17 hours of sleep a day—sounds like a dream, doesn't it? 

We've rounded up the best crib mattresses to ensure little ones are in good hands when they aren't (literally) in yours. These baby beds are functional for both babies and toddlers, feature firm surfaces, and fit standard full-size and mini cribs.

The Best Crib Mattresses 2021

What To Look For in a Crib Mattress

Shopping for baby essentials requires a lot more research than your personal purchases. Below, we've highlighted important factors to consider when buying the best crib mattress for your bundle of joy. 

Size

Standard full-size crib mattresses should be at least 27.25 inches wide by 51.25 inches long and less than 6 inches thick, according to the Consumer Product Safety Commission (CPSC). The average size of mini crib mattresses is 24 inches wide by 38 inches long. 

Fit

The CPSC suggests using your fingers as a guide to know whether or not your mattress is a safe fit. If the gap between the mattress and the crib frame is wider than two fingers, the space is not safe for your baby. Large gaps increase the risk of injury and suffocation. 

Firmness

While adults have preferences for mattress firmness, there's no other option than extremely firm for infants. This is because soft surfaces increase the risk of SIDS due to the possibility of plush bedding conforming to their small heads. It's also important to note that babies should always sleep on their backs, as opposed to their stomachs or side, and shouldn't have anything in their cribs besides a tight fitted sheet.

Room to Grow

It's no secret that kids grow out of things quickly. To avoid buying a new mattress once your baby turns 1, choose a crib mattress that is reversible, with one firm side and one soft side. Toddlers can sleep safely on mattresses that provide a balance of comfort and support.

Certifications

Many crib mattresses have a GreenGuard Gold Certification, but what does that mean? This seal ensures the product has been tested for toxins and confirmed that it contains little to no chemical emissions. Another certification is the Global Organic Textile Standard (GOTS), which verifies that the product contains a minimum of 70 percent organic fibers. Lastly, the CertiPUR-US seal means the product contains flexible polyurethane foam that has been tested and certified to ensure it's safe. 

Whether you prefer organic materials or an affordable option, there's a baby bed perfect for your little one. Keep scrolling to shop the best crib mattresses on the market.

"We just received our mattress, and it fits perfectly into our Delta Mini Crib," one reviewer said.
