If you’re in the market for the best toddler mattress, it’s likely because you’re thinking of transitioning your little one from a crib to a toddler bed. Some parents transition based on age (3 is a common age to make the move), while others may notice their dextrous little ones beginning to climb out of their crib on the earlier side. Regardless of the reason for that first big-kid bed, the toddler mattress you choose will set the tone for a comfortable night’s sleep for your kiddo.

If baby has been sleeping in a standard crib, know that you don’t necessarily need to purchase a new mattress if you’re moving them into a toddler bed; these two types of furniture use the same size mattress. But if you’d like to try something different, or you’re moving your kiddo into a twin-sized bed, our guide to the best toddler mattresses will make your decision easier. Keep reading to find the one that will ensure a good night’s sleep for your little one.

Types of Toddler Mattresses

Most toddler mattresses are made from a blend of polyester, cotton and other fibers. This provides a firm mattress for safety, but also one that’s comfortable enough for little ones to get a good night’s sleep. And while there are exceptions, mattresses tend to come in one of three options:

  • Foam. Foam mattresses are great for toddlers because they tend to incorporate features that ensure proper spinal alignment. And for little ones with allergies or parents who are concerned about potentially hazardous chemicals in traditional mattresses, foam offers a hypoallergenic solution.
  • Innerspring. This is the typical coil mattress that you likely grew up with. This type of mattress tends to offer the most support and lasts the longest. You’ll also find it slightly bouncier than a foam mattress.
  • Hybrid. Can’t decide between foam and innerspring? You don’t have to! A hybrid mattress offers the best of both worlds: good support from a coil system and the plush and contoured feel of a foam mattress, making it a great choice for young kids.

In recent years, some parents have started opting for twin-sized versions of popular mattress brands, like Purple, Nectar, Avocado and Casper (all of which offer a foam or hybrid mattress option).

What is a Standard Toddler Bed Mattress Size?

If you’ll be moving your little one from a crib to a true toddler bed, you may not need to purchase a toddler mattress. That’s because toddler mattress dimensions are often the same size that fits in a crib. However, if you’ve been using a mini crib, the mattress you have is likely smaller than a traditional toddler mattress. Another option is to move your kiddo to a twin-sized bed and use safety rails to ensure they don’t fall out. Here’s a breakdown of toddler mattress sizes by type:

  • Standard toddler mattress: 28" (L) x 52" (W) x 6" (H)

What to Look for in a Toddler Mattress

Double-sided mattresses are a great way to meet the sleep needs of both babies and toddlers without having to purchase a separate mattress, according to Sharifa Glass, MD, a pediatrician and clinical assistant professor at the Tilman J. Fertitta Family College of Medicine. “Today, many standard crib mattresses have a firmer side for infant use (ideal for babies under 12 months of age) and a softer side for toddler use (12 months of age and older),” she says. Other helpful features to look for in a toddler bed mattress include the following:

A protective cover that’s either waterproof or removable for easy cleaning. “This can help to protect the mattress from spills, stains, nighttime accidents and allergens,” notes Glass. A medium-firm to firm mattress to provide more support for a toddler’s neck and head. Good edge support.
