If your little one is not so little anymore, it might be time to go shopping for a twin mattress. But with so many options to choose from, it can be difficult to know where to start.

That’s where we come in. Below, you’ll find some general information to consider when shopping for a twin mattress, what kind of mattresses are best for kids, as well as our top six picks for the best twin mattresses for toddlers and young kids.

Toddler bed or twin bed?

In terms of furniture sizes, there are toddler beds available. The mattresses measure 28 inches by 52 inches, which is the same size as a crib mattress.

However, unless you have a crib and toddler bed combo, you may end up buying a toddler bed and then a twin bed as your child grows. That’s why some parents skip the toddler bed and move directly from a crib to a twin mattress.

In general, a twin mattress measures 38 inches by 75 inches, and a twin XL mattress measures 38 inches by 80 inches. A twin XL provides extra length, which comes in handy if you’re trying to make a bed last for many years.

We considered many criteria when selecting the best twin mattresses for toddlers, including:

  • Flammability requirements: All twin mattresses included in this list meet standard flammability requirements laid out by the Consumer Product Safety Commission.
  • Free of recalls and pending lawsuits: At this time, there are no recalls, pending lawsuits, or warnings specific to the safety of twin mattresses included in this list.
  • Verified through certifications: All the twin mattresses we picked are certified by one or more of the following:
  • Solid customer reviews: We looked at customer reviews from a variety of retailers, such as Amazon, Target, Walmart, and company websites.

Additionally, all mattresses on our list have been vetted to make sure they meet Healthline’s business standards and approach to well-being. Learn more about our vetting process.

There’s no single type of mattress that’s best for toddlers. However, here are a few general guidelines to keep in mind:

Materials

Several material options exist for toddler mattresses, including:

  • foam
  • innerspring
  • hybrid

Memory foam provides softness and isn’t as bouncy as a spring mattress — which may mean less temptation to use the mattress as a trampoline.

However, memory foam mattresses also tend to have more chemicals, so you may want to consider only those that come with materials certifications like CertiPUR-US.

Otherwise, look for a natural latex mattress, or a bouncier innerspring or hybrid model.

Firmness level

Since toddlers don’t weigh as much as older kids or adults, their mattresses don’t need to be nearly as firm in order to provide support.

As long as your child is over 12 months old, they can sleep on a softer mattress. You may want to consider something that’s medium-firm to offer a good balance.

Pressure relief

Pressure relief is less of a concern for kids than it is for adults. However, if you do want a mattress that has more pressure relief, memory foam is your best bet.

Temperature regulation

Look for a mattress with a cooling gel foam layer if your child sleeps hot. Alternatively, mattress toppers can provide temperature regulation to keep your child’s sleep more comfortable.

Safety certifications

Safety is, of course, a top priority for all things toddler-related. The Consumer Product Safety Improvement Act of 2008 (CPSIA) requires toddler beds to meet certain safety requirements.

However, this act doesn’t apply to twin-size beds. Instead, twin mattresses must meet the same flammability requirements as other adult-size mattresses.

If you’re considering a twin bed for your toddler, look for certifications like:

When shopping for a twin mattress for your toddler or a mattress of any size, you’ll want to consider:

  • safety
  • materials
  • price
  • return policy
  • warranty
  • trial period

Since some companies have generous trial periods that allow you to test a mattress and return it for a full refund, it’s worth your time to research mattresses that come with a trial period.

It’s also common for mattresses to come with beds or bedroom sets, so it’s important to note that some mattresses are made for specific manufacturers and dealers. These mattresses have to meet the same federal requirements as ones sold directly to you.

When shopping for a mattress, the decision often comes down to comfort. That said, there are a few other things to consider.

What to look for in a mattress

  • Return policies: Always ask about the store’s return policy and the fine print before purchasing. Some stores will not accept returns on pillows or mattresses.
  • Quality: Affordable mattresses are a plus, but make sure you’re not sacrificing quality for cost.
  • Price: Twin mattresses range in price from $70 to over $1,000. Remember, a higher price doesn’t necessarily mean the mattress is better. Test each bed out, read reviews, and check for warranties.
  • Trial period: Some companies offer a trial period where you can sleep on the bed and return it for a full refund if you’re not satisfied. These periods range from 10 to 365 days.
  • Warranty: Ask about the length and type of warranty. Most mattresses come with a limited warranty, but some of the more expensive brands come with a generous warranty.

Here are some questions to consider when deciding between a twin or full bed for your toddler:

  • Will you sleep with your toddler on occasion? A bigger bed might make things more comfortable.
  • Do you want a bed they can grow with? A full bed meets this need, and you won’t have to upgrade down the line.
  • Do you like the idea of having more space? A full bed offers more room to move around and limits the chances of your toddler accidentally falling out of bed.

Keep in mind that whatever option you choose, it’s important for the bed to be close to the ground to prevent injuries from accidental falls.

Twin mattresses are common, and you can buy them almost anywhere mattresses are sold. Most online mattress retailers offer twin options, and you’ll find plenty of twin models available at brick-and-mortar locations.

Once you find a mattress that works for your toddler, keeping it in tip-top shape can help you get years of use out of it and make the money you spend go even further.

Simple mattress care tips

  • Place the mattress on a box spring or foundation.
  • Cover it with a mattress protector.
  • Add an extra layer with a waterproof pad or cover.
  • Flip and rotate the mattress regularly.
  • Soak up spills right away.

When are kids ready for a toddler bed?

While some kids may be ready for a toddler bed as early as 18 months, others may stay in their crib until 2 1/2 years of age.

How long do kids sleep in toddler beds?

This can vary greatly depending on your child’s height, weight, and development. However, the CPSIA says that toddler beds are generally designed for kids at least 15 months of age and under 5 years old.

They’re also intended to hold no more than 50 pounds.

When should I switch my toddler to a twin mattress?

There are no hard and fast rules for when to transition your toddler out of their toddler bed and into a twin. However, here are a couple of considerations:

  • Manufacturer recommendations: If your child is currently in a toddler bed, check to see the weight limit and any other restrictions.
  • Comfort: If your child isn’t sleeping soundly in their toddler bed, it may be time to make the switch.

When can my toddler sleep on a soft mattress?

The American Academy of Pediatrics recommends using a firm sleep surface until your child is at least 12 months old. This is to reduce the risk of sudden infant death syndrome.

Should toddlers sleep on memory foam?

Some experts warn against chemical off-gassing from memory foam mattresses. A 2019 study indicated that memory foam mattresses do emit higher levels of volatile organic compounds during sleep.

If this is a concern for you, look for a mattress that comes with safety certifications like CertiPUR-US. Otherwise, opt for natural latex, innerspring, or hybrid models with less foam.

Can you use the same type of mattress for a loft or bunk bed?

Yes! Although, you may want to go with a memory foam model, because they tend to weigh less than hybrids and coil-containing mattresses.

It’s also important to pick a mattress with the right height. Find a model that’s no more than 7 or 8 inches tall to ensure it doesn’t clear the guardrail and increase your toddler’s risk of rolling out of bed and falling onto the floor.

What are some good twin mattress accessories?

What do you need to outfit a twin bed? Here’s a snapshot of what to buy:

  • comfortable pillows
  • a mattress protector
  • bedding, including a fitted sheet, top sheet, and pillowcases
  • a bed frame

Deciding on the right twin mattress for your toddler may require a few trips to the store, but if you do the research ahead of time, the process can go a lot more smoothly.

When choosing a mattress, make sure to check for safety standards, quality certifications, trial periods, and warranties.
