Best Mattress for Kids

Finding the best mattress for your kids is one of the most worthwhile investments you can make as a parent.

Please find out more on how to choose the best mattress for your children below, what features your kid’s mattress should have and check out our best selection of premium mattresses for kids.

Kids Mattress Sizes & Body Development

From 5 years of age and up, you will want to make a sound investment in a mattress for your children that will last. This is critical to pair with the understanding that your child will grow and develop, changing shapes and sizes as they mature. The best mattress for kids can accommodate all of these changes, provide perfect spinal support, and last for a good ten or more years.

There are three main kids’ mattress sizes that you can look at purchasing:

  • Twin and Twin XL – Twin size mattresses are commonly the smallest mattress size, approximately the size of a single bed. Twin and Twin XL are both usually in the same price range and the best budget-friendly choice for kids’ mattresses; however, they may not be big enough to accommodate all stages of growth and development a child goes through they may need replacement.
  • Full – A full-sized mattress is extra wide and usually a bit more expensive than twin and twin XL mattresses. Full-size mattresses confer additional advantages, such as being large enough to accommodate your child until they are much older. Many parents also enjoy that while their child is getting used to sleeping in a bigger bed, there is ample space on a full mattress for the parent to sit with the child, read stories with them, and so on.

Kids Mattress Types By Sleeping Position

How firm or soft a kid’s mattress is should depend on the position in which your child sleeps. At an early age, most children have a good idea of how they like to sleep, which will determine the best kind of mattress for them.

  • Back Sleepers – Back sleepers are likely to develop healthy back postures and receive the fewest problems, as long as their mattress is neither too hard nor too soft. A layered foam mattress with high-density foam or springs at the bottom, as well as skinny layers of comfort and memory foam at the top, is ideal.
  • Side Sleepers – Side sleepers are the most sensitive sleepers and often enjoy the softest mattresses possible. Getting a mattress your child can sink into is a good idea, but the spine can be displaced if it’s too soft. Look for thicker layers of memory and comfort foam in a side sleeper mattress with a lesser layer of high-density foam. Hybrid mattresses (a combo of springs and foam) are perfect for side sleepers.
  • Stomach Sleepers – Stomach sleepers need the most degree of support and require firm mattresses. If your child is a stomach sleeper, it is advised that you try to discourage them from sleeping in this position, as it can lead to the most back problems later in life. The spine gets placed out of alignment very easily, especially if they sleep on a big pillow or raise their leg. If your child insists on sleeping in this position, try to encourage them to use a flat or no pillow to help ease pressure on the spine.
  • Sleep Position Shifters – If your child shifts through more than one of these sleeping positions throughout the night, then get a medium-firm mattress that provides more back support than not to cover all bases.

Featuresof a Good Mattress for Kids

The below list is a brief discussion of five of the best toddler mattresses features and why you need them.

  • Raised Sides – This feature is appropriate for very young kids that have just made the transition from a crib into an “adult bed.” The raised sides can emulate being in a crib and allowing them to feel secure while preventing them from falling out.
  • Multiple Layers – A mattress that combines multiple layers, like a hybrid mattress, is often more effective at providing the best back support.
  • Temperature Control – Since many mattresses on the market are made using foam, it is important to ensure the mattress has a form of temperature control; otherwise, your child could wake up from overheating in the night. Ventilation layers, perforation, innerspring, and cooling material infusions are all ways that mattress manufacturers have included to prevent this problem from occurring.
  • Certified Foam – Keep an eye out for foam certifications such as CertiPUR-US, which ensure that the product has been checked and certified free of harmful chemicals that can affect your child’s growth and development.
  • Durability – The warranty of a mattress will indicate for how long the mattress will last. It is worthwhile spending a bit more on a mattress that will last the full duration of your child’s growth phase until they are ready to get a new larger mattress.
