Understanding Mattress Sizes for Kids and Teens
When selecting a mattress for your child, it’s important to understand the differences between a Single and a King Single mattress:
- Single Mattress Dimensions: Typically 92 cm wide by 188 cm long, a Single mattress is suited for younger children and small rooms.
- King Single Mattress Dimensions: Measuring 107 cm wide by 203 cm long, a King Single mattress provides additional length and width for growing bodies.
A King Single mattress bridges the gap between a Single and a Double, offering a practical choice for older children and teenagers. The extra space accommodates their growing needs and ensures a better night’s sleep.
