8 Best Full Size Beds for Kids 2024

Any parent worth their weight will tell you that their children’s sleep is crucial to their own rest and well-being. The obsession often starts during the newborn phase (who remembers diligently chronicling naptimes and sleep training?) lasting well into the toddler and kid years, when we start searching for the best toddler mattresses, best kids' mattresses, blackout curtains and noise machines.

One of the biggest transitions during childhood is moving from a crib or toddler bed to a full-size bed. While it’s up to you when and how you do this, it’s an important step that signals your kid has made it to the next stage. Here are some of the best full size beds for kids to consider when making this move.

What to look for in the best full size bed for kids

When looking for a full-size bed for your kid, start with the right thickness. "Low profile mattresses around 5 inches are great for young kids," says Dr. Chelsea Arzacon, a naturopathic medical doctor. "This height makes them easy to climb on and off. Older children can tolerate a slightly thicker mattress around eight inches or so."

Her recommendation is a firmer mattress to support their growing bodies, adding that parents should look closely at the materials mattresses are made from.

"One potential health hazard is VOC or chemicals with documented health hazards used to make mattresses flame resistant," she says.

Look for certifications such as CertiPUR-US, GOTS or GREENGUARD to know the mattress you are considering is void of chemicals. However, these certifications can sometimes come with a higher price tag. If a low-tox mattress is out of your price range, Dr. Arzacon suggests letting the mattress sit uncovered in a well-ventilated room for a month to allow these chemicals to dissipate.

FAQs

How big is a full size bed for kids?

A full size bed for kids is often referred to as a double bed, and is roughly 16 inches wider than a twin. A standard full size bed is 53 inches wide and 75 inches long, and typically offers more than enough space for growing children and teenagers.

Full size and queen beds are similar in size, with full designs being a bit more narrow and best for a single tween, teen or adult sleeper.

Is a full size bed OK for 2 kids?

Advertisement

Typically a full size bed is for one person, though in different regions and cultures a full size bed may be used to sleep more than one sibling. That's a personal choice based on the size and age of your children, as well as a variety of other factors.

Kids sharing a bedroom is pretty common, and young children making the most of an oversized bed is common in space-constrained major cities and tight apartments.

What size sheet is right for a full size kids bed?

Opt for a full size sheet for a full size kids mattress. Queen sheets are only seven inches wider and can easily work if you're in a pinch. Because you wouldn't want your sheets to be pulled so tight that they tear, most full size sheets measure 54 inches wide—a full inch wider than the mattress itself—to allow ample space for movement and breathability.

If you have a deeper profile mattress, consider buying full size sheets that come with deep pockets—these should measure at least 15 inches in height/depth.

How can I clean a full size bed for kids?

First, it's important to use a waterproof mattress cover on any children's bed—accidents happen, and nose bleeds and sippy cup spills. And markers gone awry... and the list goes on.
