Guide to Choosing a Kids’ Mattress

Selecting the right mattress for your child is a crucial decision—perhaps even more so than choosing your own. During childhood, quality sleep supports both physical growth and cognitive development, making the right mattress essential for a comfortable, restorative night’s sleep. With so many options available, finding the best mattress for kids may feel overwhelming. This guide will walk you through the key factors to consider when choosing a mattress for your child, helping you make an informed decision that supports their health and comfort.

Recommended mattresses

Some of our favourite mattress brands are:

What kids need in a mattress

  • Support and size – Growing children need a mattress that supports their spine and promotes healthy development. For younger children, a twin or twin XL mattress usually provides ample space, but as they grow, they may require a full-size mattress to ensure enough room for comfortable movement. Choosing the right size not only accommodates growth spurts but also helps your child feel secure and supported, reducing the need for frequent upgrades.
  • Age-appropriate comfort – Comfort needs vary based on age. For younger children, a soft to medium-firm mattress often provides the right balance of coziness and support. As children transition into their teen years, they may prefer a firmer mattress to support their changing bodies and various sleep positions. A medium to firm mattress offers versatility, providing both comfort and stability as their needs evolve.

Additional considerations when buying a kids’ mattress

Selecting the right mattress material is essential for comfort, durability, and even health benefits. Here’s a quick breakdown of popular mattress types for children:

  • Memory foam: Known for its contouring support, memory foam offers excellent pressure relief, making it a good choice for younger children who need extra comfort. Memory foam mattresses can reduce tossing and turning, helping children fall into a deeper, more restful sleep.
  • Innerspring: Innerspring mattresses are made with coils, providing a more traditional feel that some kids might prefer. These mattresses often have a bit of bounce, which can make bedtime fun for younger children. Innerspring models also tend to offer strong edge support, which is ideal for children who move around frequently during the night.
  • Latex: A natural and hypoallergenic choice, latex mattresses are durable and breathable, making them great for children with allergies. Latex mattresses provide a supportive, slightly bouncy feel and are known for their long lifespan, which can be a plus for parents looking for a more sustainable option.
  • Hybrid: Hybrid mattresses combine innerspring coils with foam or latex layers, providing the best of both worlds. Hybrids offer excellent support and comfort, adapting to various sleep positions as children grow. They also tend to be more breathable than all-foam options, which can help regulate temperature.

Durability and growth support

When investing in a mattress for children, durability is key. Kids’ mattresses experience more wear and tear, whether it’s from jumping or everyday use, so choosing a durable material can save you from frequent replacements. Look for mattresses with strong edges and high-density foams or quality coils, which help the mattress retain its shape and support as your child grows.

Trials, warranties, and knowing when to upgrade

When purchasing a mattress for your child, opting for one with a trial period is always beneficial. A generous trial period—often ranging from 100 nights up to a year—allows your child to test the mattress and see if it provides the right level of comfort and support. Kids, especially younger ones, may not immediately recognize what feels best, so a trial period offers peace of mind and flexibility to make adjustments if needed.

Additionally, look for a mattress with a solid warranty, generally lasting from 10 to 15 years. A good warranty demonstrates the brand’s confidence in its product and provides extra security, particularly for parents concerned about wear and tear. This added coverage is especially useful given that children’s mattresses often experience a bit more rough and tumble.

Children grow quickly, and their comfort needs can change over time. Signs that it may be time for a new mattress include visible sagging, your child’s complaints of discomfort, or noticeable wear and tear. As your child grows, ensuring that the mattress continues to provide adequate support is crucial for promoting healthy sleep. A well-timed upgrade can make a significant difference in their sleep quality, helping them wake up refreshed and ready for the day.
