How Important is Mattress Thickness for Safety?

What Safety Features Should a Bunk Bed Mattress Have?
The safety features to look for in bunk bed mattresses for kids include:
- Low Profile: A low-profile mattress reduces the risk of falls, making it safer for children climbing in and out of the top bunk.
