What's the best mattress for kids?

The best youth mattress is one that provides proper development support, and a safe night’s rest. By using one of our 5” low profile mattresses, your child will be protected by 11” of guardrail height. Our industry leading 16” guardrails are as safe as they come!

Best twin mattress for bunk bed

Each of our mattresses have been designed with safety in mind. That’s why our 5” twin mattress is ideal for growing kids with all the added benefits of a taller mattress. Maxtrix trundle beds are slightly smaller which require a special trundle mattress. Read 5 Expert Tips for Choosing Best Bunk Bed Mattress.

How do I choose the right bunk bed mattress?

Using a 5” twin, twin xl, or full mattress on both bottom and top bunks allow for more headspace and provide the safest amount of guardrail height with 11” of protection. For bigger beds, our 8” queen memory foam mattress for young adults provides a medium-firm density for optimal comfort. Read our Mattress Guide for more information.
