Mattresses for Kids

Verywell Family / Sabrina Jiang

We all spend a large portion of our lives sleeping, so it's a good idea to invest in a comfortable and supportive mattress. Kids' mattress needs will vary based on their age, size, and personal preferences. For babies up to age one, it's essential to choose a very firm mattress for safe sleep to reduce the risk of sudden infant death syndrome (SIDS.)

Whether you’re shopping for a crib mattress, twin mattress, or something larger, you'll need to know the size of the bed frame you have along with the mattress’s thickness and firmness. It’s important to know the thickness and hardness of the mattress you're buying for a child, as one that’s too thick or soft can be dangerous for young children. We carefully looked over design, including firmness and thickness, value, material, and ease of cleaning when reviewing products. 

Here are the best mattresses for kids of all ages.

Pros
  • Dual-side design

  • Hypoallergenic

  • Waterproof

To ensure safety and a good night’s sleep, most infants sleep in a crib and you’ll want a comfortable and durable crib mattress. This mattress checks those boxes. It has a dual-side design so for the first year or so, the baby can sleep on an extra firm foam side made just for infants.

As the baby grows, flip the mattress to the softer, plusher toddler side. The mattress is hypoallergenic and waterproof, so it’ll be easy to clean when the inevitable happens. At just over 8 pounds, it’s easy to lift for changing sheets and the squared edges and corners make that even simpler.

Best for Bunk Beds

Zinus 6-Inch Foam and Spring Twin Mattress Set

Zinus 6 Inch Foam and Spring Twin Mattress 2 Piece Set for Bunk Beds / Mattress-in-a-Box

Amazon

Pros
  • Budget-friendly

  • Safe for bunk beds

Cons
  • Springs may become noisy

  • Chemical smell reported by some reviewers

Finding the right mattress for a bunk bed requires some specific criteria. Most bunk beds have twin-sized mattresses but double-check your set as some require the twin XL size. Standard twin mattresses are between 8 and 12 inches thick. For the top bunk, the mattress should not exceed 7 inches thick. Otherwise, it can extend past the bed’s guardrails.

The more guardrail space, the safer the bed is. The Zinus Sleepmaster mattress is easy to clean and at only 6 inches thick, it’s safe and secure for a bunk bed. The affordable set comes with two mattresses, so once you have the bed, order these and some sheets, and the bunk bed is ready.

Best for Allergies

Puffy Queen Mattress

Puffy Mattress

Puffy

Pros
  • Stain-resistant Zip-N-Wash cover

  • Fits on any type of bed frame

Cons
  • Not sold in stores (only online)

  • On the heavier side

If your child has allergies, it’s best to choose memory foam or natural latex mattress for their bed. Avoid any fluffy pillow top covers, as they can accumulate dust mites. For that reason, a Puffy mattress is a good choice for kids. It’s a foam mattress that comes with a stain-resistant Zip-N-Wash cover that can easily be cleaned.

To manage allergies, the cover comes right off so you can wash it seasonally (or whenever allergies flare) as an extra step to remove dirt, germs, or allergens. These mattresses ship for free in 1 to 3 business days and fit on any type of bed frame.

If an organic mattress choice is important to you, the Avocado Green mattress is a top-of-the-line choice. These non-toxic mattresses are made with organic wool, cotton, and latex. For vegans, they even sell a Vegan Certified mattress.

Sensitive sleepers will appreciate how the natural materials wick away moisture and the air flows better than a polyurethane foam mattress. This made in America brand offers a full refund for up to a year after purchase and has a 25-year warranty.

Best for Play Yards

Dream On Me Foam Pack and Play Mattress

Dream On Me 3" Fiber Playmat, Excellent Comfort & Support, Waterproof Vinyl Cover, Greenguard Gold Certified, Environment Safe Playmat

Amazon

Pros
  • Anti-bacterial and waterproof cover

  • Affordable

  • Lightweight

Cons
  • Spot or wipe clean only

  • Should never be used on bassinet level of play yard

  • Not safe for babies under 6 months old

If your child will be using a Pack 'N Play (or other play yard) for frequent naps, overnight sleeping, or at grandma’s house, it might make sense to invest in a mattress. While the addition of the mattress makes the play yard less portable, it improves comfort and may lead to longer sleep. This pad fits a Pack 'N Play and most other play yards (double-check measurements to be sure).

It has an anti-bacterial and waterproof cover. The mattress is nearly 3 inches thick, providing a good support base. For added safety, this mattress is equipped with full-perimeter wires along the mattress border, so it keeps the sides, corners, and edges of the mattress firm and allows it to maintain its shape. However, never use this mattress on the top level of the play yard when it is set up for a bassinet, as that arrangement is a safety hazard.

Construction Type: Foam | Firmness: Not listed | Thickness: 3 inches | Sizes Available: Pack 'N Play only

Good to Know

Before purchasing an additional mattress for your child's play yard, you'll want to use the mattress provided. If you need to replace the mattress, choose one that fits snugly without any gaps and is firm and thin for safe sleep. A mattress should be firm and flat, and if you choose to put on a sheet, make sure it fits snugly.

What to Look For in Mattresses for Kids

Thickness

Kids need different mattress thicknesses depending on their age. It’s important to know the thickness and hardness of the mattress you're buying for a child, as one that’s too thick or soft can be dangerous for young children. For example, infants should not sleep on an adult mattress. They need a firm crib mattress that is no more than 6 inches thick.

Children may use their crib mattresses in a toddler bed once they graduate from their crib. As your child gets older, they will move on to the regular thickness of mattresses for adults, which is anywhere from 8 to 14 inches.

Firmness

Just as with thickness, you'll want to match a mattress's firmness with the age of your child. A super plush mattress is not safe for babies. When shopping for a mattress for a baby, you want a firm sleep surface, meaning it should not indent when an infant is lying on it.

No matter the age of your child, you want them to get a good night’s rest, and that is really going to depend on the firmness of their mattress. Kids have different preferences, but to be on the safe side, know that older children typically do best on a medium-firm mattress. One that’s too soft or hard can cause pain or discomfort. Medium-firm will help with spinal alignment and support during sleep.

Size

Whether you’re shopping for a crib mattress, twin mattress, or something larger, you'll need to know the size of the bed frame you have (and what the company’s manual recommends). The following dimensions are standard:

  • Crib: 52 inches x 28 inches
  • Twin: 75 inches x 39 inches 
  • Twin XL: 80 inches x 39 inches
  • Full: 75 inches x 54 inches

Once you’ve noticed your toddler getting too big for their crib mattress, you can move up to a twin-sized mattress. The only difference with a twin XL mattress is that it adds 5 extra inches in length for taller children. A full-sized bed is what many adults and older teens sleep on. Larger options include queen and king-sized mattresses.

Frequently Asked Questions

  • Should a child's mattress be firm or soft?

    Babies need to sleep on a very firm mattress to reduce the risk of SIDS. Even for older kids, it is a good idea to use a firmer mattress, as a softer one can increase the risk of suffocation.

  • Can kids use adult mattresses?

    Adult mattresses are usually thicker and often softer than is recommended for children. Babies should never sleep on an adult mattress, as doing so increases the risk of SIDS. Also, it is recommended for toddlers and other young children to sleep on a mattress that is firm and low to the ground to prevent falls.

  • Can a child use a memory foam mattress?

    Memory foam mattresses are not safe for babies or young children. Sleeping on a soft surface that molds to the body increases the risk of SIDS and suffocation.
