How To Find The Right Mattress Size For Your Growing Teen

If you have kids getting to that stage where they have outgrown that small twin mattress or simply need a new mattress, your first thought might be to simply purchase the cheapest mattress you can find since they might soon outgrow it anyway.

Perhaps you have a boy or girl who’s gone through a bit of a growth spurt and no longer fits on the twin race car bed that they’ve had since they were six.

But what type of mattress does a growing adolescent youth need? Are there even multiple mattress options for kids? Why is the choice of the mattress even crucial for children when they are growing up?

A good night’s sleep is vital for the development of a child. Growing children need rest, and they need proper support when sleeping to help with growing pains and adequate body support.

Furniture Fair understands the importance of a good night’s sleep for everyone, and we want to use our years of experience selling quality mattresses and beds to help you find out the best way to find a good mattress for your growing kids.

Read on to find out how to find the perfect mattress for your growing youngster and why proper sleep and support are essential for developing teens and young adults.

How To Find The Right Mattress Size For Your Growing Teen

Step 1 - Find The Right Length Mattress

When purchasing a mattress for a growing teen, an important thing to consider is the length of the mattress. Nobody wants to sleep on a mattress that only fits most of their body.

The last thing your child needs is to have their feet hanging off the edge of the bed feeling uncomfy and left vulnerable to classic horror movie monster tropes.

Keep your kid’s toes safe from discomfort and the boogeyman by making sure to buy a mattress that fits their growing adolescent frame. Below you will find a breakdown of common mattress sizes and which ones are best for your kids.

Twin Mattress

A twin mattress is probably the first thing that comes to mind when you think of a kid’s mattress. Small, reliable, and affordable, the twin mattress is the most commonly used mattress for kids and some teenagers.

Twin mattresses are 38” X 75” long or about six and a quarter feet. A twin mattress will do just fine into adulthood for many teens, provided the mattress has proper support and comfort levels to help them sleep properly.

The downside to a twin mattress comes if your child outgrows the length of the bed. If you happen to have a future basketball star or a kid who just happens to excel at growing, a twin bed will not cut after a certain point.

Full Mattress

A full mattress is another option to consider for a growing teen. If you have a huskier young adult who needs a bit more space to sleep comfortably, a full mattress may be a better option than a bare twin mattress.

Full mattresses are 53” X 75” long or about six and a quarter feet. Many people may not realize that a twin mattress and a full mattress are the same lengths. If you are looking for a longer mattress to replace your twin mattress, a full mattress will not do the trick.

A bonus that a full mattress provides is that when your child heads off to college, you can convert that mattress into a guest room mattress without the guest feeling like they are sleeping on a tiny bed.

Twin XL Mattress

If your teen has already outgrown their twin mattress and requires a longer bed, a twin XL mattress may be the next viable option to consider. A twin XL mattress will support your growing young adult into their college years without taking up too much space.

Twin mattresses are 38” X 80” long or about six and a half feet. Twin XL mattresses are perfect for smaller rooms where saving space is a priority.

The downside to Twin XL mattresses is that once your child leaves home, the mattress may not have the same multifunctional uses that a full or a queen mattress would have.

Queen Mattress

Another option to consider is a queen mattress. Queen mattresses fill out a single teens bedroom nicely and provide ample room for any growth. Plus, when your child is grown, the mattress can be repurposed for another child or a guest room.

Queen mattresses are 60” X 80” long or about six and a half feet. If you have a teen going through a growth spurt and needs a new mattress, a queen mattress is an excellent option to consider for their bedroom.

Step 2 - Have Your Kid Try Out The Mattress Before You Buy

While most parents make intelligent purchase decisions for their teens, a mattress replacement purchase is a decision that you need to get their help with. Like adults, teenagers have different needs regarding sleep support, and there is no one-size-fits-all mattress.

As children develop into their teen years, they may face a unique set of sleep challenges. Sleep is crucial to a developing adolescent teen, and a lack of proper sleep can affect emotions, personalities, academics, and social development.

Sleep is essential to the brain for helping teens with memory attention and thinking creatively and abstractly. Proper rest allows teens with academic tasks such as tests and information retention and skill-based tasks needed for getting that first job.

Sleep is also paramount in helping with mental health issues such as depression, anxiety, and other health concerns. While sleep is by no means a cure-all solution to mental health, a good night's rest can help keep teens calm as they adjust to more responsibilities and social relationships.

During adolescence, the body goes under rapid physical changes, and proper sleep is essential to ensuring that the body develops appropriately. Chemical balances can be thrown off by a lack of adequate sleep, leading to health issues later in life.

Up to 45% of young adults aren’t getting the recommended 8 hours of sleep necessary to stay healthy, and as many as 23% of teens report some levels of insomnia.

With technology, social distractions, and the everyday struggles that are developing teens face, an uncomfortable mattress shouldn’t be adding to the mix.

Your teen should be able to rest comfortably while being supported properly to encourage proper sleep and a full circadian rhythm.

An old mattress will make sleep harder to obtain, which in turn can have adverse effects on your growing teen’s physical body and their academic and social life.

Have your teen test out mattresses in-store or take the bedMATCH rest test to help determine which mattress is their preferred mattress.

After finding the perfect mattress, not only will you have a comfortable bed but also a well-rested, alert teen who is ready to face life head-on.

Step 3 - Choose A Mattress That Will Fit Your Child Until College

If this is the second mattress that you’ve ever bought for your child, you should be buying to last for the rest of your kid’s stay in your home. If you anticipate your child growing even taller than they already are, buying the same size twin mattress may not be the best option.

Suppose your child outgrows the mattress once you’ve bought it. In that case, you may end up having to purchase another mattress or subjecting your teenager to sleeping on an uncomfortable mattress which can affect everything from fatigue to your child’s grades.

Choose a mattress that will fit your child until they are ready to move out for college. A better quality mattress will last about ten years, which is perfect for keeping your child well-rested until the time comes to move out and start their own life.

Step 4 - Consider Uses For Your Mattress After Your Child Moves Out

Your child won’t stay young forever, and as sad as that life change may feel at the time, seasons change, and the time comes to move on to a new way of life. Something you may want to consider is giving your teen’s mattress a new way of life as well.

Consider repurposing your teen’s mattress in a guest room when you are shopping for a new mattress. When the time comes for your son or daughter to move out, their bed can still be put to good use and will be there when they come home to visit.

Save money by purchasing one mattress and repurposing it once your child moves out. Buying one mattress rather than two will save on your costs and use less material to help you feel better about your purchase.

Ready To Find The Right Mattress For Your Teenagers?

Now that you know what mattress sizes are available and why proper sleep is vital for kids going through growth spurts and adolescence, you can be ready to find the perfect bed that your youngster will appreciate and use to get a good night’s sleep.

Find out which of the four standard sizes, twin, twin XL, complete, or queen, is suitable for your teen’s needs, and remember to have them test the mattress themselves before purchasing.
