When it comes to the best mattress available for children, our top recommendation would have to be the Big Kid’s Bed (BKB) from Nest Bedding. Nest chooses materials that are affordable, comfortable, durable, and safe to create this mattress meant for growing kids.

You can choose a BKB in twin, twin XL, and full sizes. A twin mattress is excellent as a child’s first bed but if you want to make sure you’re choosing a bed they can grow into, the twin XL or full mattress might be the better option. Nest also lets parents add on a latex pillow and a bi-fold mattress foundation. 

The construction of the BKB keeps it simple with two foam layers, a fire protection barrier, and a mattress cover. Thermic Phase Change fabric wraps around the mattress, promoting a cooling surface for a child to ensure they do not wake up in a sweat.

Instead of potentially harmful chemical fire barriers, the BKB relies on hydrogenated silica to keep the mattress from going up in flames.

The comfort layer is 2 inches of Energex™ Temperature Responsive Foam, a material that further promotes cool, undisturbed sleep. The base layer is 5 inches of Edge Support Base Foam, providing children with a bed they won’t just roll out of in the night.

Nest offers a 100-night trial with the BKB, giving your child time to make sure it feels comfortable and supportive. The bed also includes the security of a lifetime warranty, making sure the BKB lives up to Nest’s promised comfort for the many years your child will use it.

The next best mattress for kids on the market is the Saatva Youth. This mattress was specifically designed with the younger ones in mind. It is not the most affordable option on the market, but if you want to prioritize high-quality sleep for your child, then the Saatva Youth is definitely a good option to consider. 

The Saatva Youth mattress is available in three sizes. This includes a twin size, twin XL, and a full-size mattress. You can choose to buy the mattress with or without foundation. Two options for foundations are available. This includes a 4.75-inch high foundation. A higher option, measuring 8.75 inches in height, is also available. 

The mattress features a dual-sided design. One side is made for children between the age of three and eight years old. Once your child reaches eight years of age, simply flip the mattress over. Organic cotton is used as a cover for the mattress, which also helps to reduce your child’s exposure to harmful toxins. 

The mattress comes with free white glove delivery. This means the company will deliver the mattress and set it up for you. They will also remove the current mattress from your child’s bed. The purchase of the mattress is accompanied by a 15-year warranty. 

There is a 120-night home trial that is also offered by the manufacturer of the Saatva Youth mattress. This allows your child to sleep on the mattress for a few months before deciding if they are able to experience an improvement in their sleep quality.

Many parents express concerns about the materials inside the mattresses their children use. For peace of mind, some parents choose to invest in mattresses constructed with natural materials. Our top recommendation for a natural mattress for children is the JoyBed LX. It balances natural materials with an inexpensive price tag.

The JoyBed LX comes in all the standard sizes, though we would recommend a twin, twin XL, or even a full mattress for kids. JoyBed characterizes the mattress’s feel as medium-firm. Its surface provides the support children need for pain-free sleep.

The JoyBed LX draws upon the traditional innerspring mattress design for its construction. However, instead of standard spring coils, the LX has a layer of pocketed coils for responsive, motion-isolating support.

These coils are topped with cotton and wool for heat-wicking cushion, along with potato plant fibers to meet flammability standards. The mattress’s cover is GOTS certified organic cotton, a breathable material that encourages airflow.

JoyBed offers a 120-night sleep trial with the LX, letting your child test out the bed and make sure it is right for them. It’s also backed by a 10-year warranty, protecting your investment from potential defects.

Best Mattress For Kids Buying Guide

Even when looking at the best options that are available when buying a mattress for your kid, you may still be uncertain regarding the specific options to choose from. You need to consider the right size, mattress type, and several other factors. 

To help make the process of choosing a mattress that will be perfect for your child easier, we share a comprehensive buying guide below. We also take a look at some of the most common questions that people tend to ask when they are interested in buying the best mattress for children. 

What is the best size mattress for kids?

One of the first things you need to consider is the mattress size that will be most ideal for your child. This will ensure your child has enough space to sleep comfortably. 

You will need to take the age and size of your child into account. Looking to buy the best mattress for toddlers is different from buying a mattress that will be used by a teen. 

Babies and toddlers are generally comfortable on a crib mattress. The standard dimensions for a crib mattress are 28 inches by 52 inches. 

As the child grows older, you need to start looking at larger mattress sizes. This generally ranges from a twin-size to a full-size mattress. 

The dimensions for these mattresses are as follow:

  • Twin mattress measures 38 inches by 75 inches
  • Twin XL mattress measures 38 inches by 80 inches
  • Full-size mattress measures 54 inches by 75 inches

A young child will be able to sleep on a twin size mattress, but this may not be an ideal option for larger and older children. 

How much does the best mattress for kids cost?

Mattress prices differ significantly. Whether you are looking to buy a mattress for your child or one for the main bedroom – you will notice that the prices differ a lot from one brand to the next. There are also different types of mattresses available. Some are more affordable than others. 

Since the prices are so different for the mattresses that are available, it would be a better idea to start the entire shopping process with a budget in mind. 

Before you start looking at the mattresses that you can buy for your kid, take a closer look at your own budget, decide how much money you will be able to spend on the mattress. 

When you start the shopping process, it becomes much easier when you know what your budget allows. This gives you an opportunity to filter products based on the amount of money you can spend on the best mattress for kids. 

A twin-size mattress costs anything from $100 – the prices can go as high as $1,000. In some cases, it may even be more expensive than $1,000 to buy a twin-sized mattress. When you know you are only able to spend $500 on a mattress, as an example, you will be able to filter out the options that cost more. 

What type of mattress is best for kids?

When buying a mattress for your kids, you should not only ensure you buy the right size product. Additionally, you also need to consider the fact that there are several different types of mattresses on the market. 

Each of the mattress types that are available comes with pros and cons that you will need to take into account. Some mattresses may be more comfortable for certain children. It is important that you take some personal factors of your child into account here too – such as their age, size, and weight. 

The main types of mattresses that you will find on the market include:

  • All-foam mattresses: These are very popular and only consist of foam layers. Memory foam is often used in all-foam mattress design. This helps to provide contouring. There will usually be a high-density foam at the base of the mattress. This particular foam helps to provide support to the surface and also makes the mattress more durable. Children who are very young should not sleep on all-foam mattresses. These mattresses are great for older children, however. 
  • Innerspring mattresses: Another popular category of mattresses would be those that feature an innerspring system. Some options use coils that are individually wrapped. Others will rather use standard springs. The innerspring system provides better durability to the mattress. These are also firmer and sturdier mattresses. They are appropriate for all ages and can accommodate most sleeping positions. 
  • Hybrid mattresses: These are still relatively new to the market, but have grown popular among both young and old. Hybrid mattresses combine the best features of the two main mattress types that are traditionally available. These mattresses use a foam design at the top, which is supported by layers of spring or coil. Hybrid mattresses are also good for most children. The downside is the fact that a hybrid mattress tends to be much more expensive than the other two options. 

What to look for when buying the best mattress for children?

Mattress size and type are two important factors that you should look at when you buy a mattress for your child. The budget is another important factor that we looked at. In addition to these factors, there are a few additional things that you should take into account. This will ensure you are able to provide your child with an opportunity to sleep better and reduce their risk of suffering from complications that have been linked to sleep deficiency. 

The firmness of a mattress you buy should be taken into consideration. Young children – particularly those who have not yet reached an age of 18 months – should be provided a firm mattress. This ensures the child will not sink into the mattress while they sleep. 

Older children have different factors that should be taken into consideration. Sleeping position is one such factor. A foam mattress that is soft may be appropriate for children who sleep on their side. On the other hand, when the child sleeps on their back, the mattress should ideally be firmer. This ensures their spine is aligned while they lay down in their bed. 

Durability is also something that you should look out for. Children are prone to jump on their beds – and this can quickly wear the bed out. Your child may also be more likely to spill snacks and drinks in their bed. When this happens, it should not have a significant impact on the lifespan of the mattress.  


Looking at the best mattress for kids can be tough. There is a wide variety of mattress options available. There are a few factors that need to be taken into account. This includes factors related to the child that will sleep on the mattress. Such factors include the child’s age and weight. Budget is another factor that needs to be taken into consideration. We looked at the top mattress options you can buy for your child. This helps to reduce the risk of your child suffering from sleep deprivation.
