Choosing the Perfect Kids’ Mattress for a Great Night’s Sleep

A good night’s sleep is essential for a child’s growth, development, and overall well-being. That’s why selecting the right kids’ mattress is just as important as choosing the perfect bed frame. At Millie & Jones, we offer a carefully curated selection of high-quality, supportive, and safe mattresses designed specifically for children of all ages, from toddlers to teens.

What to Look for in a Kids’ Mattress

When shopping for a children’s mattress, there are several key factors to consider:

  • Firmness & Support – A mattress that provides proper spinal alignment is crucial for growing bodies. Look for options that balance comfort with support to ensure restful sleep.
  • Breathability & Temperature Regulation – Many of our mattresses feature breathable materials such as memory foam, pocket springs, or eco-friendly fillings to help regulate body temperature.
  • Hypoallergenic Materials – If your child suffers from allergies, consider a hypoallergenic mattress designed to minimise dust mites and allergens for a healthier sleep environment.
  • Durability & Longevity – Kids grow quickly, so investing in a mattress that will last through their childhood and beyond is a smart choice.

Kids’ Mattress Sizes & Styles

We stock a range of children’s mattress sizes to fit every type of bed:

  • Toddler Mattresses (70 x 140 cm) – Ideal for transitioning from a cot to a first bed.
  • Single Mattresses (90 x 190 cm) – The most popular choice for kids’ beds, bunk beds, and high sleepers.
  • Continental Single Mattresses (90 x 200 cm) – Perfect for continental-style beds requiring extra length.
  • Small Double Mattresses (120 x 190 cm) – Great for growing kids, teenagers, or those who love a little extra space.
  • Double Mattresses (135 x 190 cm) – Perfect for teenage beds and those requiring more sleeping space.

Mattresses for Bunk Beds, High Sleepers & Mid Sleepers

If you’re buying a mattress for a bunk bed, high sleeper, or mid sleeper, it’s essential to choose one with a maximum height of 15cm for safety reasons. We offer a selection of bunk bed-friendly mattresses that provide the perfect combination of comfort and safety.

Eco-Friendly & Sustainable Options

We understand that parents are increasingly looking for sustainable mattresses that are both safe for their children and kind to the environment. Our eco-friendly kids’ mattresses use responsibly sourced materials, such as 100% recycled foam or FSC-certified fillings, ensuring a greener future for the next generation.
