What to consider before buying the best full-size mattress for kids?


When it comes to a child’s mattress, the denser, the better. Press your hands together at the side of the mattress, if you can push it easily, it’s not dense enough.


We all know this is a good idea, the mattress is gonna see spilled drinks, throw-up, pee, and probably poop. Even if it’s Spiderman‘s fault, you don’t want it on the mattress.


Dust mites can be a problem for all kids, especially those with allergies. Markers can be a problem for the mattress. So, make sure you get a mattress that is washable.


Be sure you read on the mattress and make sure there are no chemicals included. Avoid any mattress with chemicals, they can make your child sick.

Future is important:

When you go to buy a mattress, remember that if it’s durable enough, it can last through adolescence. There’s no sense in having to buy another one.


Make sure there’s good airflow in the room when you get ready to set up the mattress. You will notice a strange smell when you unpack it. The intensity of the smell will vary depending on the materials used to make the mattress.

Certi-PUR US:

A certification program administered by a not-for-profit organization. This certifies that no harmful chemicals are used in making the mattress.
