Why Mattress Thickness Matters for Kids’ Beds
Mattress height is critical for bunk beds, mid sleepers, and high sleepers to ensure safety by keeping children below guard rails. Our low-profile kids mattresses provide the perfect balance of safety and support without added bulk. Thicker mattresses offer additional support and pressure relief for heavier or older sleepers, promoting a restful night's sleep. Choosing the right mattress thickness also impacts spinal alignment and overall comfort, which are essential for a growing child's healthy development. Need help purchasing the right fit? Our expert team can guide you to the perfect mattress for your child’s bed and sleeping needs.
Sleep Well, Grow Strong
At Millie & Jones, we understand that a child’s mattress should do more than just feel soft. It must support healthy posture, regulate temperature to keep kids cool, and help them wake up refreshed and energized. Our kids mattress range includes specially designed memory foam single mattresses, pocket spring single mattresses, and open coil options, all made with natural materials to reduce allergens and provide durability. We offer a variety of single mattress types tailored to personal preferences and different sleeping positions, ensuring every child finds their perfect single mattress.
Choosing the Best Kids Mattress: Key Considerations
When shopping for a new single mattress for your child, consider their preferred sleeping position and individual needs. Side sleepers may benefit from a soft single mattress that cushions pressure points such as shoulders and hips, while back or front sleepers often require firmer mattresses to provide additional support and maintain proper spinal alignment. Our single mattresses range includes options with memory foam for pressure relief, latex for plush comfort, and hybrid mattresses that combine pocket springs with foam layers for balanced support and softness.
