Best Twin Mattresses for Kids and Toddlers

Verywell Family

It’s hard to say whether the transition to the big-kid-bed milestone is more exciting for the child or for the sleep-deprived parent. While there aren’t strict safe sleep guidelines for kids after age one, there are still some considerations to make when selecting your child’s new twin mattress.

Before hitting the store or checking out, parents and caregivers should consider the construction of the mattress and materials as some of them may offer a waterproof casing or are hypoallergenic. It’s also important to pick a mattress with the right amount of firmness for your child’s body and age so they are supported comfortably as they continue to grow. When mattress shopping, a basic rule of thumb to remember is that a firmer mattress is ideal for toddlers while softer options are better for big kids.

Here are the best twin mattresses for kids and toddlers.

While this isn’t an all-organic mattress, it has a CertiPUR-US certification, which means it uses very few chemicals in the manufacturing process. The mattress is 10 inches thick and comes in both twin and twin XL sizes. It also comes with a 10-year limited warranty and 100-night sleep trial.

Construction Type: Foam | Firmness: Medium Firm | Thickness: 10 Inches | Sizes Available: Twin, Twin XL, Full, Queen, King, California King

Good to Know

Alisa Baer, MD, Pediatrician, and Co-Founder of The Car Seat Lady, LLC advise parents to keep their child in a crib until they are 3 years old, and the AAP recommends keeping your child in a crib until they are “35 inches tall, or when the height of the side rail is less than three-quarters of their height (approximately nipple level).”

If your budget allows, Dr. Baer recommends investing in a mattress that is as organic as possible. "GOTS- and GOLS-certified are best,” she says.

Best Memory Foam Mattress: Casper Original Mattress

Casper Original Foam Mattress
  • Designed for spine support

  • Breathable materials to prevent overheating

  • Removable machine-washable cover

  • Very heavy at 79 pounds

  • Might have slight odor (but usually goes away within a couple of days)

  • Can’t be flipped

Once your child is out of their crib, they have the option to sleep on a foam mattress, but you need to be sure you get one that is firm and supports their growing body. The Casper foam mattress is designed with varying degrees of firmness throughout to provide optimal spinal support.

Additionally, there is a layer of perforated foam in the mattress to provide air circulation so your kiddo doesn’t wake up a sweaty mess throughout the night. Finally, it’s designed to support any sleeper—whether they sleep on their back, side, belly, or all over the place. The medium-firm mattress is delivered in a box and comes with a 100-night free trial.

Construction Type: Memory Foam | Firmness: Medium | Thickness: 11 inches | Sizes Available: Twin, Twin XL, Full, Queen, King, California King

Best Affordable: Linenspa 6-Inch Spring Mattress

Linenspa 6-Inch Spring Mattress
  • Works with box springs, slatted beds, and metal grids

  • Layer of foam over springs for extra comfort

  • Springs can be noisy

  • Not designed for all sleeping types

There aren’t any bells and whistles when it comes to this mattress, but don’t let that or the price trick you into thinking it’s not good quality or comfortable. It has two layers of padding on top of the springs, making it 6 inches thick with firm support.

Linenspa created the low-profile bed specifically for kids to keep them closer to the ground (in case of falls) and to fit traditional kid bed frames like daybeds, trundle beds, and bunk beds. The bed comes in twin and twin XL sizes and can be purchased with a platform bed frame.

Construction Type: Innerspring | Firmness: Firm | Thickness: 6 inches | Sizes Available: Twin, Twin XL, Full, Queen, King, California King

With such great comfort and quality at a bargain price, this twin mattress from Signature Sleep is a winner. With foam at the top and bottom for comfort, the core of the 8-inch mattress is filled with 480 coils for solid support. It's reversible too, so you can flip it as necessary to extend its life. The foam is CertiPUR-US certified, meaning it doesn’t contain any flame retardants, mercury, or other potentially harmful chemicals.

This mattress is vacuum-sealed and shipped in a small box, so it’s easy to drag to any room in your house. Once you cut it out of the bag, it expands to its full size. Parents give this mattress high marks, saying it’s supportive and doesn’t sag over time. Some note an odor when first unboxing it, but they say that goes away quickly.

  • Weighs 80 pounds

  • Can have a slight odor that needs a little while to air out

Pediatrician (and safety expert), Alisa Baer, MD, favors mattresses that are as chemical-free as possible for kids. While she does not recommend any specific mattress manufacturer or brand, her research has led her to prefer twin mattresses that meet GOTS and GOLS certification, which she believes to be the strictest of all the certifications regarding toxicity.

The Naturepedic Verse Organic Mattress is Certified to the GOTS Standard and is made with only certified organic, non-toxic ingredients—this means no polyurethane foam, flame retardants, glues, biocides, chemical water repellent treatments, and other harmful materials. The mattress is designed to promote air circulation to prevent overheating while sleeping and has a firm feel which is perfect for growing kids. It’s made from organic cotton and wool and will snuggly fit most bed frames.

Construction Type: Foam and Soy Foam | Firmness: Medium-Firm | Thickness: 9 inches | Sizes Available: Twin, Twin XL, Full, Queen

Best For Back Sleepers: Amerisleep AS2 12" Memory Foam Mattress

  • Cooling layer to prevent overheating

  • Works with any bed frame

  • High quality, durable materials

  • Can’t be flipped

  • Not for side sleepers

  • Might not be quite as firm as some sleepers like

Once a baby independently reaches the rolling developmental milestone, parents can let out a sigh of relief if they choose to sleep in a position other than their back, but some kids still prefer that position even when it’s no longer a requirement. The Amerisleep AS2 mattress is designed specifically to support back (and belly) sleepers with its medium-firm feel.

The 12-inch thick foam mattress has four layers to provide stability, air circulation, and support. It will fit most bed frames and can also perform well when placed directly on the floor. With a 20-year warranty, the manufacturer promises it won’t sag in the middle over time.

The mattress comes in both twin and twin XL sizes. Amerisleep will ship your mattress compressed in an eco-friendly box, and you have 100 nights to try it before committing.

Construction Type: Foam | Firmness: Firm | Thickness: 12 inches | Sizes Available: Twin, Twin XL, Full, Queen, King, California King

Best for Spine Support: Helix Sunset Mattress

Helix Sunset Mattress
  • Breathable construction

  • Plush/soft

  • Designed for optimum spine support

  • Pillow top, so it can’t be flipped for longevity

If your kid thrashes all over the bed while they sleep, this is the mattress for them because it’s crafted to support side sleepers and those who toss and turn throughout the night. Since sleeping in odd positions can put pressure on the spine, the Helix Sunset mattress is designed with foam layers to relieve stress and possible pain. It also cushions typical pressure points for side sleepers.

While the mattress is on the softer side, the memory foam layer offers added support, and the hybrid design also creates better airflow for temperature regulation. With a 10-year warranty and a 100-night sleep trial, you can test the USA-made mattress out before committing.

Construction Type: Foam and memory foam | Firmness: Med-Soft to Soft | Thickness: 12 inches | Sizes Available: Twin, Twin XL, Full, Queen, King, California King

Best for Hot Sleepers: Colgate EverTrue Grand Twin Mattress

Colgate Evertrue
  • Waterproof cover for protection against accidents

  • Designed for air circulation to avoid overheating

  • Bedbug and dustmite-proof

  • Hypoallergenic

  • Cover can be somewhat loud

  • Can’t be flipped (one side designed for infant sleep, the other meant for toddler sleep)

The majority of Colgate’s mattresses are the size of a standard crib, but they do make a handful of twin mattresses that are made with equally high safety standards. The EverTrue Grand twin mattress is extra-firm on one side and a little softer on the other to provide different comfort options. The two sides are separated by a honeycomb mesh layer that provides stability, support, and excellent air circulation.

Pediatrician Alisa Baer likes that this mattress is compliant with all federal and state flammability requirements without the use of fire retardant chemicals, which she says can be especially dangerous for kids. Parents will appreciate the easy-to-clean waterproof cover for late-night potty accidents.

Construction Type: Foam | Firmness: Medium-Firm | Thickness: 7.5 inches | Sizes Available: Twin

Best Innerspring: Zinus Support Plus 12-Inch Extra Firm Mattress

Zinus Support Plus 12-Inch Extra Firm Mattress
  • Great for stomach sleepers

  • Quilted top and layers of foam to add softness without taking away from firm support

  • Built with durable materials for longevity

  • Springs may start to make noise over time

  • Needs 72 hours to fully expand from box

  • Can’t be flipped

Dr. Baer recommends opting for a firm pick when selecting the first mattress for kids, since they may not know what they like yet. "A firmer mattress is typically ideal [because] you can always make it softer by adding a topper, but you can't make a soft mattress firmer.” The Zinus 12-inch extra firm mattress is a good place to start.

The 12-inch twin mattress is made with extra coils for added firmness and is especially great for kids who sleep on their stomachs. Don’t worry, though, it’s not hard as a rock—it has three layers of foam on top of those coils to provide added comfort. It’s also CertiPUR-US certified and is made without the use of chemical flame retardants.

Construction Type: Innerspring | Firmness: Extra Firm | Thickness: 10-12 inches | Sizes Available: Twin, Full, Queen, King

Final Verdict

Selecting your child’s twin-size mattress leaves a lot more room for options than a crib mattress. You can’t go wrong with the Saatva Mattress (view on Saatva) because it’s designed to support people with a variety of sleep habits. But, if you’re looking for an all-organic option, the Naturepedic Verse (view at Amazon) is the clear winner.

What to Look for in a Twin Mattress for Kids and Toddlers 


Look closely at the materials used, especially if your child has allergies of any kind. Not all mattresses are made from organic fabrics and fillers, some are hypoallergenic while others aren’t, and some have waterproof casings. Consider all of your options carefully before selecting your child’s mattress. 


Consider what firmness your child needs to get a full, restful night of sleep. When selecting the mattress, make sure it’s designed to support their spine and bones, as their developing body will constantly change and you want a mattress that evolves with them. 


There are various types of mattresses including memory foam, gel, springs, and hybrids. Do your research for each type and determine what is best for your child. Ideally, look for a mattress with a cooling component to help ensure your child doesn’t overheat while sleeping. 

Frequently Asked Questions

  • When should toddlers move to a twin bed?

    The AAP recommends moving your baby to a toddler bed when they are 35 inches tall or when the height of the side rail hits about nipple level, or less than three-quarters their height. However, it should be done before this if your child is able to crawl out of their crib on their own. 

  • Should I get a twin or full-size bed for a toddler?

    Either size is safe for your toddler, so it’s a matter of preference and space. They may adjust to a twin-size bed a little quicker because it’s closer in size to their crib or toddler-size mattress, but they will eventually adjust to a full-size bed just as well.
