Frequently Asked Questions
Will the Kids' Twin Mattress fit my bed frame?
The mattress is designed to fit all traditional twin bed frames. It measures 38” x 75” x 5.5” ( LxWxH).
Are there flame retardants?
While many of our competitors use toxic chemical fire retardants, we do not. Instead, we use a layer of viscose material sewn into our cover. Viscose material is made from reconstituted wood pulp. We quilt this material into our mattress covers for a safer, non-toxic solution.
Is the mattress comfortable for my child?
Our Kids' Twin Mattress is made with the same technology and comfort that Newton is known for in our crib mattresses. Many parents tell us their little ones start sleeping better from the first night, and we couldn’t be happier. Try it yourself risk-free with our 100-night trial.
What sheets should I use?
We recommend using a cotton sheet for the most comfortable and breathable sleep for your child. Because our mattress is 5.5" thick, it's best to find sheets with an 8" pocket to fit snuggly on the mattress.
Twin Mattress For Kids: The Complete Buying Guide
While on the hunt for the right twin mattress for kids, you may have some questions. For example, how firm should it be? Which materials are safe and which aren't? And does it need to be waterproof?
These are all important things to consider, but you don't have to find the answers all by yourself. We've compiled a detailed guide of everything you need to know about buying a twin mattress for your child.
From comfort to safety, we’ve got you covered.
Why do parents love twin mattresses for kids?
Twin beds are typically 38” by 75”. This makes them big enough to fit most kids and growing teens. Many adults also find a twin mattress to be comfortable enough for them to sleep on. It’s very versatile.
And when it comes to working within your budget, choosing a twin bed can be cost-effective, as it’s often more affordable, and a quality one can last your child for years.
Twin mattresses are also great transitional options from a toddler bed. If your toddler is quickly outgrowing their bed, this option will be big enough for them but not too overwhelming in size.


When to transition your child to a twin bed
Now that you know more about twin beds and why they’re so popular, let’s discuss when to move your child into a bigger bed.
While there’s not a “right” age to make the move, here are some readiness signs to watch for:
Getting too tall for the crib
Starting to potty train and need to be able to get to the bathroom on their own
Climbing out of the crib
Indicating they want a “big kid” bed through actions or words

What to look for in a twin mattress for kids
Materials used
At Newton Baby, our Crib Mattress’s Wovenaire® Core is made of 90% air to provide just the right amount of firmness for babies and toddlers. And it’s GREENGUARD Gold Certified, meaning it exceeds the highest industry emissions safety standards.


Firmness
The firmness of a mattress will influence how much support and body contouring it offers your child. Firmer mattresses usually give users more support, while softer ones allow sleepers to sink in more.
So, which one is better? There is no “ideal” mattress firmness for older children because everyone’s body and preferences are different.
However, it’s important to note that the level of firmness is extremely important for infants because they need the right support for proper development.
Washability
Kids can be messy, but you don’t want their mattress to be. Look for a mattress that is easy to clean in case of any accidents or spills.
The Newton Kids’ Twin Mattress is a great choice. As the only 100% washable twin mattress, both the removable cover and 3-piece core are completely washable. The cover can go in the washing machine, and you can rinse the core out in the shower.
Being able to wash your child’s mattress can help keep their room sanitary. This is especially important if they have allergies, asthma, or eczema.


Temperature regulation
Unfortunately, many mattresses on the market tend to trap heat. If your little one is prone to sweating or overheating while they sleep, this isn’t great news.
Ideally, you want a mattress that allows for airflow and better temperature regulation, as this will reduce sweating and offer your child the safe, restful sleep they deserve.
Free Trial
Have you ever brought a mattress home only to discover it was uncomfortable? It’s not fun, and the experience can make you feel like you’ve wasted money. To prevent this, pick a mattress you can test.
Newton offers a 100-night trial, which gives you plenty of time to decide if the mattress is right for your child. Other companies may also provide a trial period, but you’ll want to read the fine print to see if any restrictions or fees are associated with it.
