How to Choose the Best Mattress and Sleep Accessories for Kids
Choosing the right mattress for your child is about much more than finding something soft and comfortable. Children spend a significant amount of time sleeping, and their sleep environment can influence how rested and comfortable they feel when they wake up.
From the right mattress firmness and size to pillows, mattress protectors, sheets, and duvets, every part of a child's bed plays a role in creating a comfortable and practical sleep setup.
With so many options available, however, parents often wonder: What type of mattress is best for kids? How firm should it be? Do children need special pillows? Which sleep accessories are actually worth buying?
This guide covers the most important factors to consider when choosing a mattress and sleep accessories for kids.
Why Choosing the Right Mattress for Kids Matters
Children's sleep needs change as they grow, but one thing remains constant: they need a comfortable and supportive place to sleep.
A good children's mattress should provide a balanced sleeping surface that supports the body while remaining comfortable enough for restful sleep.
The right mattress can also make everyday life easier for parents. A durable mattress paired with washable bedding and a quality mattress protector can better handle spills, accidents, dust, and regular wear.
Instead of choosing a mattress based only on price or softness, think about your child's:
-
Age and stage of growth
-
Sleeping position
-
Body size
-
Comfort preferences
-
Bed and room size
-
Temperature preferences
-
Mattress durability needs
Considering these factors can help you choose a bed your child can comfortably use for years.
1. Choose the Right Mattress Size
The first decision is determining which mattress size works best for your child's bedroom and future needs.
Twin Mattress
A Twin mattress is one of the most popular choices for children.
It provides enough sleeping space for most young children and teenagers while taking up relatively little floor space.
A Twin mattress can be ideal for:
-
Smaller bedrooms
-
Bunk beds
-
Kids transitioning from toddler beds
-
Shared bedrooms
-
Growing children
If bedroom space is limited, a Twin mattress is often the most practical option.
Twin XL Mattress
A Twin XL mattress provides approximately the same width as a standard Twin but offers additional length.
This can make it a smart option for taller children and teenagers or parents who want a mattress that may remain suitable as their child grows.
Full/Double Mattress
If there is enough bedroom space, a Full or Double mattress provides considerably more sleeping room.
A larger mattress can be useful for children who move around frequently while sleeping and may also remain practical as they grow into their teenage years.
Quick Tip
Don't choose a mattress only for your child's current size. Think about how long you expect them to use it.
Spending slightly more on an appropriately sized mattress today may help avoid replacing it simply because your child outgrows it.
2. What Mattress Firmness Is Best for Kids?
Parents frequently assume that children need extremely soft mattresses because they weigh less than adults.
However, softer doesn't automatically mean more comfortable or more supportive.
For many children, a medium-firm or comfortably supportive mattress can provide a good balance between cushioning and stability.
The ideal firmness will still depend on factors such as your child's age, body weight, sleeping position, and personal preference.
You generally want to avoid a mattress that allows your child to sink excessively into the surface.
At the same time, an extremely hard sleeping surface may not feel comfortable.
The goal is balance: supportive without feeling unnecessarily rigid.
3. Consider Your Child's Sleeping Position
Just like adults, children develop preferred sleeping positions.
Watching how your child naturally sleeps can help you understand which mattress feel may suit them.
Back Sleepers
Children who primarily sleep on their backs may benefit from a balanced mattress that provides consistent support across the body.
A medium to medium-firm feel is often worth considering.
Side Sleepers
Side sleepers generally appreciate some cushioning around areas such as the shoulders and hips.
A mattress with a slightly more cushioned comfort layer can provide a comfortable sleeping surface without sacrificing overall support.
Combination Sleepers
Many children move between several positions throughout the night.
For combination sleepers, a responsive medium or medium-firm mattress can be a versatile choice because it provides a balance between cushioning and ease of movement.
4. Choose the Right Mattress Type
There isn't one mattress construction that is automatically best for every child. Different mattress types provide different benefits.
Foam Mattresses
Foam mattresses are popular because they can provide comfortable cushioning while remaining relatively lightweight.
They're also available across a wide range of price points.
A quality foam mattress can be a practical option for children's bedrooms, particularly when paired with a supportive base.
Memory Foam Mattresses
Memory foam adapts to the body's shape and can provide a more contouring feel.
However, children who naturally sleep warm may prefer more breathable constructions or mattresses that incorporate cooling materials.
Innerspring Mattresses
Traditional innerspring mattresses use interconnected coils for support.
They often provide a responsive feel and good airflow.
They're also available in many affordable options, making them a practical choice for growing children.
Pocket Coil Mattresses
Pocket coil mattresses use individually wrapped coils that move more independently.
They can provide strong support while reducing movement across the mattress.
For older children or teenagers, a quality pocket coil mattress can offer a comfortable balance between support and durability.
Hybrid Mattresses
Hybrid mattresses typically combine coils with foam comfort layers.
They can provide:
Support from the coil system + cushioning from the foam layers.
A hybrid mattress may be particularly useful when you're looking for something your child can continue using into their teenage years.
5. Don't Automatically Buy the Cheapest Mattress
Children grow quickly, so it can be tempting to purchase the least expensive mattress available.
However, price should not be the only deciding factor.
A very low-quality mattress may lose its shape or comfort more quickly, potentially requiring replacement sooner than expected.
Instead, focus on overall value.
Look at:
-
Construction quality
-
Mattress materials
-
Support
-
Durability
-
Warranty
-
Expected lifespan
-
Comfort
-
Manufacturer reputation
The goal isn't necessarily to buy the most expensive mattress. It's to find a quality mattress that fits your budget and your child's needs.
6. Consider Temperature and Breathability
Children can become uncomfortable when their sleeping environment feels too warm.
If your child frequently complains about being hot at night, consider mattress materials and bedding designed with breathability in mind.
Options may include:
-
Breathable mattress covers
-
Pocket coil or hybrid constructions
-
Cooling fabrics
-
Moisture-wicking sheets
-
Lightweight duvets
-
Breathable mattress protectors
Remember that the mattress is only one part of temperature regulation.
Heavy blankets, non-breathable sheets, warm pajamas, and bedroom temperature can all affect how warm the bed feels.
7. Always Add a Mattress Protector
If there's one sleep accessory parents should seriously consider purchasing with a child's mattress, it's a mattress protector.
Kids' mattresses are more likely to experience accidental spills, food stains, sweat, and nighttime accidents.
A quality mattress protector creates an additional barrier between your child and the mattress.
It can help protect against:
-
Accidental spills
-
Sweat
-
Stains
-
Everyday dirt
-
Moisture
Protecting the mattress can also make maintaining a cleaner sleep environment much easier.
Waterproof vs. Water-Resistant Protectors
For younger children, a waterproof protector can be particularly practical.
Older children may be comfortable with a thinner breathable protector depending on their needs.
Whichever type you choose, check the manufacturer's washing instructions and ensure the protector is compatible with your mattress.
8. Choose an Age-Appropriate Pillow
Parents often focus heavily on the mattress while treating the pillow as an afterthought.
But the pillow is another important part of your child's sleep setup.
Children generally don't need the same thick, high-profile pillows that many adults prefer.
A pillow should comfortably support the head and neck without pushing the head excessively upward.
The right pillow will depend on factors such as:
-
Age
-
Body size
-
Shoulder width
-
Sleeping position
-
Mattress firmness
For younger children, a lower-profile pillow may be more appropriate, while teenagers may prefer pillows closer to standard adult sizes and profiles.
For infants and very young children, follow current pediatric safe-sleep guidance regarding pillows and other soft bedding.
9. Choose Comfortable and Breathable Sheets
Sheets are in direct contact with your child's skin for hours every night, so comfort and practicality matter.
Look for sheets that are:
-
Soft
-
Breathable
-
Easy to wash
-
Durable
-
Correctly fitted to the mattress
Cotton and other breathable fabrics are popular choices for children's bedding.
If your child tends to sleep warm, prioritize breathability instead of simply buying the highest thread count.
A very high thread count doesn't automatically mean a sheet will sleep cooler or feel better.
10. Select the Right Duvet or Comforter
The ideal duvet depends largely on bedroom temperature and the season.
A heavy duvet may feel comfortable during a cold Saskatchewan winter but become uncomfortable during warmer months.
An all-season duvet can be a practical option because it provides flexibility across changing temperatures.
Parents may also consider keeping separate lighter and warmer bedding options for summer and winter.
Whichever option you choose, make sure it is easy to maintain and appropriately sized for the child's bed.
11. Make Bedding Easy to Clean
A beautiful children's bed isn't very practical if every component is difficult to wash.
Kids' bedding should be designed for real life.
Prioritize:
Machine-washable sheets + washable pillowcases + mattress protector + washable duvet cover.
Having an extra set of sheets is also extremely useful.
If there's a nighttime spill or accident, you can quickly replace the bedding rather than waiting for everything to wash and dry.
12. Don't Forget the Mattress Foundation
Even a quality mattress may not perform as intended if it's placed on an unsuitable foundation.
Depending on the mattress, compatible options may include:
-
Platform beds
-
Slatted foundations
-
Box foundations
-
Adjustable-compatible foundations
Always check the mattress manufacturer's requirements.
If using a slatted bed, pay particular attention to the recommended spacing between the slats.
Proper support underneath the mattress can help maintain its shape and performance.
13. Think About How Quickly Kids Grow
A mattress for a six-year-old may still be in use when that child is ten or twelve.
That's why future needs should be part of your purchasing decision.
Ask yourself:
Will this mattress still be large enough and supportive enough several years from now?
For older children, choosing a slightly larger mattress or investing in a more durable construction can sometimes provide better long-term value.
14. Let Your Child Test the Mattress
Parents naturally make the final purchasing decision, but children should have some input whenever possible. When shopping at a mattress store, allow your child to lie on several suitable mattresses rather than testing each one for only a few seconds. Giving them enough time to relax helps them properly compare different firmness and comfort levels. Pay attention to whether they find a mattress too firm, too soft, or comfortably balanced. While your child’s preference should not be the only factor in the decision, their feedback can be valuable when choosing between several appropriate mattress options.
15. Build a Complete Kids' Sleep Setup
Instead of thinking about the mattress as an isolated purchase, consider the complete sleeping environment.
A practical kids' sleep setup may include:
-
A supportive mattress
-
A compatible bed frame or foundation
-
A waterproof or breathable mattress protector
-
Comfortable fitted sheets
-
An age-appropriate pillow
-
A suitable duvet or comforter
-
An easy-to-wash duvet cover
-
An extra sheet set
These components work together to create a bed that's comfortable for children and easier for parents to maintain.
Common Mistakes Parents Should Avoid
Even with good intentions, it's easy to make mistakes when buying a mattress for a child.
- Choosing a mattress that is too soft instead of balancing comfort and support.
- Buying a mattress based only on your child’s current age and size without considering future growth.
- Skipping a mattress protector, which can help protect against spills, stains, and accidents.
- Choosing bedding mainly for colours or character designs instead of comfort, breathability, fit, and easy washing.
- Using a bed frame or foundation that is not compatible with the mattress.
- Ignoring your child’s comfort preferences when they are old enough to provide useful feedback.
