Picking the right mattress size

Understanding mattress sizes and dimensions before you begin shopping will save time and frustration later. The many size options can lead to confusion? Don’t worry. We’ve got you covered.

Choosing the right mattress size for you child

You have three great options when it comes to choosing your child’s mattress size – Single, Super Single, and Queen. Keep in mind, as mentioned earlier, that the best mattress investment will be one that can accommodate your child during the growing years. In this case the right size can save money in the long run.


Single mattresses are the most common mattresses purchased for children and usually the most economical way to go. Basically, they are narrow but full length. They are best suited for smaller kids, lighter kids, and kids who have tighter spaces. When you need to economize with your space, like in college dorm rooms or a nursery transformed into a bedroom, a Single is the best option.

  • Single mattresses measures 36 x 75 inches.
  • Generally, Single mattresses are best for younger school-age children. Once many children hit middle-school and the growth spurts that come with it, it will be time to size up for better comfort.


  • Economical
  • Fit tight spaces


  • Little room to grow
  • Shorter usable lifespan for many children

Super Single

A Super Single is less commonly purchased, but still a great option. The only difference here is in Width. Because a Super Single is wider, it may accommodate a growing child for more years and therefore present a better investment. It will work well with taller kids who still need to save on space. It will not work with Single sheets that you already own, however.

  • Super Single mattresses measure 42 x 75 inches.
  • Can work well for older kids and taller kids, or those expected to grow much taller. Super Single mattresses can accommodate a child through college if space is tight.


  • Economical and space-saving
  • Allows some room to grow


  • Can be less comfortable for older and larger kids, with less room to move.
  • Shorter usable lifespan than Queen .


A Queen mattress can be an ideal choice for children if space allows. The Queen size is much wider than but the same length as a Single/Super Single . This is the best option for the maximum longevity and usability as well as comfort as your child grows. However, when space is an issue, a Single or Super Single will win out.

  • Queen mattresses measure 60 x 75 inches.
  • With a total of 24-18  inches more in width, a Queen mattress is versatile and great for any child’s needs.



  • Best long-term value
  • Allows room to grow


  • Not ideal for small rooms
  • More expensive than Single


How different types of mattresses compare for kids

As mentioned before, a mattress is made up of a series of layers. The support core, which holds the shape of the mattress and supports weight, is usually a denser, stronger construction in the case of foam mattresses. In a hybrid mattress, the support core is often the innerspring layer. This layer is topped with the comfort layers, which often consist of memory foam or some other material designed to provide pressure relief. Each of the mattress types below will have different benefits for your child and will appeal to different types of sleepers.

Memory foam: Memory foam mattresses are made of 100% foam. Without the innerspring component, a memory foam mattress is more portable, so it’s offered by many of the bed-in-a-box companies online. This type of mattress often consists of layered foam, and each layer may be designed for a different purpose. Memory foam is not washable, so a good cover is mandatory. For children, who are often lighter-weight than adults, memory foam can be comfortable and provide all the support they need while offering great pressure relief. Be sure that the support layer is adequate to provide spinal support and alignment, and that the foam is non-toxic.

Innerspring: An innerspring mattress will often provide more firmness and overall structure than a foam mattress. The strength and durability of a higher-quality innerspring mattress can be important for kids who are likely to test the mattress to its limits at times. Generally, the lower the gauge of the coils used, the stronger and firmer the mattress. Pocketed coils provide maximum airflow, but innerspring overall is a better option for kids who sleep hot. This type of mattress won’t trap body heat.

Hybrid: Here is the best of both worlds. A quality hybrid mattress will offer the support and durability of innerspring, with the comfort and plush feeling of foam. Most hybrids feature foam comfort layers with an innerspring support core.

Latex: A latex mattress can be a good alternative to memory foam in that it offers more strength and support. Look for all-natural latex that is certified and safe. This can be an eco-friendly option and a great combination of comfort and durability.
