Best Bunk Bed Mattresses + Buying Guide

Because most standard quality Twin-sized mattresses are made with multiple layers of comfort foams and supportive springs, many are often too bulky for bunk beds; trying to fit a regular Twin mattress in a top or bottom bunk will leave little room for climbing in and out of bed and even topple over the guardrails, posing a serious safety risk.

3. Consider Mattress Comfort & Support

While choosing a custom mattress thin enough to fit into a top or bottom bunk without adding too much height is essential, most custom thin bunk bed mattresses lack the support and comfort layers that growing children need.

To make sure that your new bunk bed mattress will provide the same quality designs of a regular Twin memory foam or innerspring mattress, pay attention to the mattress material and construction.

Because of the need to keep height down to seven inches, most bunk bed mattresses are made with either innerspring or foam – but not both. And while it is possible for an all-spring or -foam mattress to provide sufficient comfort for adults, most of the time it isn't enough to provide the pressure-relief and support needed for a growing child's bones.
