Which Factors to Consider While Choosing a Kid Mattress?

Some factors need to be considered while choosing a mattress for our children. Children’s adaptability is not as exact as adults because of their body structure. Adults can sleep on hard, firm beds, but it will be inappropriate for the little ones. Let’s take a look at the consideration factors:

Which Factors to Consider While Choosing a Kid Mattress

Mattress Size

The right size of mattress with suitable height is the primary consideration. A larger mattress may not seem a problem, but a mattress that is less height than the kid is a severe problem.

Imagine your kid’s leg is out of the bed, or the head is almost off the mattress edge. Can they sleep comfortably? No, right. That’s why you must get a mattress appropriate to your child’s height.

Mattress Firmness

Mattress firmness is where the comfort lies. The proper spinal alignment is essential while sleeping, and firmness helps this. There are various firmness mattresses available, and each of these is for specific individuals.

Take a look:

  • Extra soft/ultra plush: Extra soft or ultra plush mattresses are for the lightest sleepers, like newborn babies. These mattresses are incredibly soft.
  • Soft/plush: Soft and plush mattresses are suitable for patients with back pain and between one and two-year-old babies.
  • Medium-firm: This firmness provides an excellent combination of support and comfort. It is suitable for those who sleep in a variety of positions.
  • Firm: A firm mattress is great for good support but not soft enough for children. Stomach sleepers find this amazing to sleep with.
  • Extra firm: This type of firmest is not suitable enough for everybody to gain comfort. But it is a good option for heavy sleepers.


A mattress with quality materials lasts long and provides convenience. Various materials are used in a mattress, and a quality mattress must have memory foam, latex, cooling gel memory foam, cotton, wool, and silk.

Each mattress consists of multiple layers, and the materials are used there. So, check the mattress package for the material information used for the layers.

Just like adults, kids’ mattresses have many variants. A right-sized mattress will provide quality sleep over time. So first, understand which size of mattress is appropriate for your children.

Babies Mattress Thickness

Generally, crib mattresses are the foremost choice for a newborn baby or older up to three years. The dimension of a crib mattress is 28 inches wide and 52 inches long. The thickness of a crib mattress is from 4 to 6 inches. If you want less thickness, buy one with the same thickness as your horizontally rotated two fingers.

Toddler Mattress Thickness

Kids from three to eight years old are considered to be toddlers. Our kids start growing in this stage, and a medium-firm mattress suits them. A twin-size mattress is the most fitting mattress for toddlers, with a dimension of 38″ x 75″ and 6 to 8 inches thick. This type of mattress’s firmness significantly supports the toddler’s body.

Older Children’s Mattress Thickness

While twin mattresses are perfect for toddlers, these can still be used if your kid is getting older. However, if your kid needs more space, replace the twin mattress with a twin XL. A twin XL is 80 inches long and 38 inches wide, which is a little bigger than the previous one and doesn’t take up too much space. The thickness is 9 to 12 inches.

In addition, if you’re planning for the long term so that your kid can alternatively use the mattress even in their teenage period, consider getting full-size bedding.

Final Words

Many questions wander around our heads when a baby comes into our life, and they start growing. Kids are not the same as us and require specific items to help their overall well-being. Bedding is one of the considerable matters for kids, and the question: Is 6 Inch Mattress Enough for Kids? is thinkable.

However, I’ve clarified that the thickness of your kid’s mattress depends on their age and growth, but it is still preferable for kids. Always ask about the materials and double-check the quality while purchasing. Consider replacing the mattress if your kids are going through any sleep issues.
