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.

The good news is we’ve done the research for you. Here is some general information to consider when shopping for a twin mattress, as well as our top eight picks for the best twin mattresses for toddlers and young kids.

Now that the crib is packed away, it’s time to get your toddler sleeping in a bigger bed. Depending on their age and size, you have a couple of choices.

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

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.

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, and trial periods.

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.

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.

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 smoother.

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