When picking a mattress for your child, it’s crucial to keep in mind that it will reasonably grow by a significant margin before the mattress requires to be replaced. As a result, parents may want to reconsider larger sizes to ensure their children won’t outgrow their beds.


  • Twin sizes 38W” x 75L”. Since this is the smallest mattress size possible, these sizes measure more than six feet in distance, making them suitable for most kids. It is also usually the cheapest size.
  • Twin Extra Long (XL) is 38W” x 80L”. The extra five inches of length above a standard Twin may help teenagers that are somewhat tall and expected to grow more.
  • Total or Double measures 54W” x 75L”. Full/Double mattresses are usually ideal for children because they are wide enough to accommodate restless sleepers and long suitable for any less than six feet tall. Many kids can sleep on their Full/Double mattress until they reach adulthood.
  • Queen is 60W” x 80L”. Queen-size mattresses average six feet wide and nearly eight feet long, presenting them excessively large for most children. Origins can usually save some money by opting for a Full/Double alternatively, which offers an adequate room at a cheaper price-point.
  • King sizes 76W” x 80L”. A King-size mattress is too large for most children and will be an expensive investment for parents.
  • California King measures 72W” x 84L”. Like King-size mattresses, the California King is too big and expensive to be suitable for a kid’s bed.


Selecting the Best Mattress Firmness Level for Your Kid


Although a ‘Medium Firm’ design is generally regarded the most popular, it usually pretends the sleeper is an adult of average weight (between 130 and 230 pounds). Every kid will have different firmness preferences, and they’ll usually find a softer mattress to be more comfortable when they’re more youthful and still to grow.

You can also choose mattress firmness according to your child’s body weight and favored sleep position. It’s important to note that children who scale less than 130 pounds tend to feel most relaxed on mattresses that are ‘Soft’ to ‘Medium.’ In opposition, heavier children typically prefer mattresses that are ‘Medium’ to ‘Firm.’

Concerning sleep position, side sleepers find softer mattresses to be more convenient, between ‘Soft’ and ‘Medium Firm,’ or a 3 to 6 on the 1-to-10 scale. A smoother mattress surface provides wider and heavier parts of the body to sink lower into the mattress, ensuring healthy spinal alliance for the side sleeping position. Stomach sleepers typically favor firmer mattress surfaces to prevent their pelvis from falling too profoundly and pulling the spinal alignment. Back sleepers make things simple, as they usually enjoy the widely accepted ‘Medium Firm’ setting.



Durability is essential for selecting a child's mattress because there is a great chance they will grow significantly during the bed's lifespan. As such, parents may not want to invest in a long-lasting, potentially costlier mattress (such as a latex or airbed model) and may opt for a cheaper, less durable model instead (such as an innerspring or memory foam mattress). However, models prone to early sagging may not be a good choice since sagging can impact a mattress's supportiveness.

Does Your Child Like to Jump on the Bed?


Parents who are worried about their child bouncing on their mattress (and potentially hurting themselves) may want to choose a mattress made of foam and latex with no spring components and soft to medium firmness. These mattresses are not very responsive and offer little to no bounce, reducing the child's risk of getting hurt.
