Frequently Asked Questions
What size mattress is best for a child?
A twin mattress is the most common size for kids moving out of a toddler bed. It works well through the early school years. A full mattress is a better long-term investment for older kids or anyone who wants more room. For taller teens, a twin XL adds extra length without taking up as much space as a full.
What firmness level should a kids mattress be?
A medium-firm mattress is generally the best starting point for children because it supports healthy spinal alignment and is comfortable for back and side sleeping positions. Avoid very soft mattresses for young children because they may not provide enough support for growing bodies.
