What Makes a Mattress Ideal for Kids?
Children’s bodies are constantly developing, so their mattresses need to offer the right combination of support, comfort, and safety. Here’s what matters most:
1. Proper Support
A supportive mattress ensures the spine stays aligned throughout the night. All Millie & Jones mattresses are designed with structured foam and spring systems that balance softness with stability, promoting healthy posture for growing children.
2. Safety
For top bunks and high sleepers, safety is essential. That’s why the Millie & Jones 15cm range (including the MemoryDream 15, PocketRest 15, and ComfortSleep 15) is perfectly sized for bunk beds, combining comfort with compliance to British safety standards.
3. Comfort
Children need a mattress that’s soft enough for pressure relief but firm enough for support. Each mattress in our range has been carefully tuned to a medium to medium-firm feel, giving just the right level of comfort.
4. Durability
Built to withstand everyday use, Millie & Jones mattresses are made with high-quality foams and fabrics designed to keep their shape and comfort over time.
5. Hypoallergenic Design
Every Millie & Jones mattress includes a removable, washable cover to help keep your child’s sleep environment fresh and hygienic - ideal for allergy prevention and peace of mind.
