Common Types of Twin Mattresses for Kids

You can get a twin mattress for kids in the traditional innerspring, hybrid, or full foam. 

When searching for the best twin mattress for kids, their age will often determine their needs. For example, a young child may be a tummy sleeper and need a twin mattress that is quite firm. 

An older child may become a side sleeper and do better on a memory foam topper on top of an existing mattress a new hybrid twin mattress. 

If you start your young child on a firm coil mattress and they need more cushion, they may do better with a memory foam topper as they get older.

Budget is obviously a consideration when trying to choose the best twin mattress for kids. If you need to start with a budget purchase, you can still create a comfortable bed for your child. 

Adding a down alternative or memory foam topper to a firm mattress can warm up a bed in cold situations. If your child is prone to falling out of bed, you may want to choose a budget twin mattress for kids and put it on a wool camping pad or directly on the floor for a short time to avoid injury.

The best twin mattress is one that will grow with your child. The first two mattresses in this listing include an organic kids mattress and a memory foam mattress with a firmer side for a young child and a softer side for a pre-adolescent. 

Carefully review your child’s favorite sleeping position. If your child is a tummy sleeper at age 10, the best twin mattress for them as they age may not be one of the dual-sided mattresses or anything with a thick memory foam layer.

Things to Consider Before Buying a Twin Mattress for a Child


The best twin mattress for your child is one that suits their most common sleeping position. 

If your child loves to curl up and snuggle down on their side, a memory foam mattress can be a great choice. 

There is no one size fits all twin mattress for kids, but firmer is better for younger children.


Twin mattresses for kids are generally about a yard wide and about 6 feet, 6 inches long. Of the mattresses for kids in this review, the weights can vary widely. 

If you are looking for an RV mattress for kids, the 6 inch innerspring may be the best choice to protect your mileage and the structure of your rig. 

Even carrying memory foam toppers will not add a great deal to your overall weight. Height varies widely among the best twin mattresses on this listing. 

If you have a standing daybed with a trundle and need a mattress for kids or guests on the trundle, a lower profile mattress can work there while you put a taller, more plush mattress for kids on the top bed.


Even if you can’t afford the best twin mattress in this listing, you can still get a really nice twin mattress for your child. 

One of the big benefits of the top two beds is that they can be flipped to suit an older child that needs a softer bed. 

If you can only get one density mattress for kids to suit your child right now, consider a hybrid for steady airflow and coolness.


Generally, a mattress for kids weighs no more than 60 pounds. 

If your child’s bedroom is small, you’re working on bunk beds, or you need a mattress for an RV, consider getting a mattress for kids that includes innerspring. 

Yes, it may be heavy, but it will hold shape and be easier to rotate on the schedule to choose. A mattress for kids should be rotated every 6 months.


Generally, memory foam or hybrid mattress for kids should not be flipped top to bottom because the base of the mattress is about support, not sleep. 

However, the top two mattress for kids options in this list are designed for flipping; one side is for tummy sleeping toddlers and one side is for side sleeping tweens.


  1. What is a good twin mattress for a child?

    The one that suits their sleeping style and temperature needs. A hot tummy sleeper on a soft foam mattress will be miserable, and a cool side sleeper on a firm coil mattress will not sleep well.

  2. What mattress firmness is best for a child?

    Young children sleep better on a firm mattress; older children may sleep on their side and do better on something softer.

  3. What is the standard size of a twin mattress?

    75 inches long by 35 inches wide, with a bit of variation. If your child will be very tall, you can get a twin XL mattress for kids, which is 80 inches long.

  4. How long should a mattress last?

    You should expect 10 years of life out of your mattress if it gets rotated as required and doesn't serve as a bounce house.

  5. What is the average twin mattress for kids pricing?

    With a range from just over $100 to just over $1,000 in this listing, you can expect to pay around $500 for a quality twin mattress.

  6. Is a twin mattress safe for a toddler?

    If your toddler can get out of their crib on their own, they may be safer on a twin mattress on a low frame or on the floor.

  7. What kind of mattress should a 4-year old have?

    Until a child is 8 or 9, their sleeping styles may be constantly changing. A firm mattress is safer at this age.

  8. When should I switch my toddler to a twin mattress?

    Toddlers should be good to go from a crib to a twin when they can get out of the crib on their own.

  9. Is a memory foam mattress good for a child?

    It's a great option for an older child who is a side sleeper. As a general rule, mattresses made of memory foam have a deeper sinking feel than a coil mattress.

  10. Which is better for a toddler, foam or spring mattress?

    Toddlers are often tummy sleepers and may well do better on a spring or coil mattress.

It’s Bed Time!

If your child is continent nearly all of the time and ready for a big kid bed, the Saatva Youth Mattress is one of the best twin mattresses for your growing child.
