As adults, we know there's a huge difference between poor- and high-quality mattresses—we've all had at least one restless night while staying in a hotel or guest bedroom. To make sure your child doesn't lose sleep due to discomfort, we've rounded up the best kids mattresses that parents say their little ones love.

Your child's sleeping habits are more important than you might think. Not only does a full night of rest give your child enough energy to take on the day, but studies have also shown that kids with healthy sleeping patterns have a better overall mental and physical well-being. Children who aren't reaching the adequate amount of hours per night are more likely to become overweight and struggle with depression. To set your little one up for success, create a consistent bedtime routine with soft music and lighting and a superior sleeping surface from a reliable brand, such as Purple or Casper.

The Best Mattresses for Kids

Kids Mattress Size Guide

Here are the standard mattress dimensions suitable for babies, toddler, and older kids, according to the Consumer Product Safety Commission (CPSC) and the Better Sleep Council (BSC). Note: If there is a gap between the mattress and the frame larger than two fingers, you need a bigger mattress. Too much free space can cause injuries, so it's important to know your frame measurements before purchasing a mattress.

Mini crib mattress: Mini crib mattresses are baby beds that are smaller than 49.75 inches long and 24.375 inches wide, averaging at about 38 inches long by 24 inches wide. These mattresses are generally used in portable baby cribs, child care centers, and play yards at home.

Crib mattress/toddler bed: Mattresses for full-size cribs should be at least 51.25 inches long by 27.25 inches wide with a thickness less than 6 inches. Although crib mattresses and toddler beds can be the same size, toddler beds are usually much lower to the ground and don't have bed guards.

Twin mattress: Twin mattresses typically measure 75 inches long and 38 inches wide. This size is ideal for children who are ready to transition from a toddler bed to a "big kid" bed, plus it works well for bunk beds.

Twin XL mattress: Twin XL mattresses are 80 inches long by 38 inches wide. These are an excellent choice for kids who could use an extra 5 inches of space.

Full mattress: Full-size mattresses are 75 inches long and 53 inches wide, so they are the same length as twin mattresses but 15 inches wider. This bed size provides a good amount of space for children who move around in their sleep.

Best Types of Mattresses for Kids

Firm: Shopping for your newborn? Here's what you need to know: Firm is good, and soft is bad. Ultra-supportive beds help prevent the risk of SIDS, while mattresses that are too soft could potentially lead to suffocation.

Soft: Once your child is about 18 months old, they can sleep on a soft mattress, like pillow top designs. You can either buy a mattress that has a soft side for infants and a firm side for toddlers or invest in a whole new bed they can continue to grow into.

Innerspring: Innerspring mattresses are safe for children of all ages, offering optimal support that won't sink. They contain coils that provide extreme durability, whether your kid is sleeping or jumping (it happens).

Foam: Foam mattresses are a great option for kids because they are comfortable, quiet (compared to innerspring mattresses), portable, and usually less expensive than other models. Memory foam mattresses can help older children with pressure relief.

Hybrid: Hybrid mattresses combine layers of foam with coil systems, meaning they are a cross between innerspring and memory foam mattresses. Although less common, hybrid mattresses can also feature latex instead of foam. Overall, hybrid mattresses are an ideal mix of soft and supportive.

Best Overall: Saatva Youth Mattress

best mattress for kids

The Saatva Youth Mattress is available in twin, twin XL, and full bed sizes, plus two foundation heights of 4.75 and 8.75 inches. The best part about this innerspring mattress is that it supports kids between the ages of 3 and 12 years old thanks to its dual-sided design. Both sides feature an organic cotton cover (with a waterproof finish!) and a supportive coil system, but they have different types of material beneath the cover to suit different stages of life. On the side for ages 3 to 7 years old, there is a five-zone foam layer that promotes proper spinal alignment. The side for 8- to 12-year-olds contains a high-density foam to help keep your child cool and comfortable throughout the night. This mattress has a 180-night sleep trial and a 12-year warranty.
