Best Bunk Bed Mattresses on Amazon

By Katie Dyal

Bunk beds are a great way to save space. For many kiddos, these stacked beds serve as their first real beds. When selecting a mattress, you’ll want one that’s of the highest quality and utmost safety.

Bunk beds aren’t like traditional beds and this is reflected in their mattresses. Mattress thickness is a factor, which is why our top picks stay in the six to eight-inch range. If you use a regular size, it can keep the guard rails from doing their job or set its sleeper too close to the ceiling. Different rules apply here, so read your frame’s requirements carefully. We’ve chosen some great options that fit the bill. Read on to find our top picks for the best bunk bed mattresses on Amazon and what to consider when shopping for your own.

What to Look For in Bunk Bed Mattresses on Amazon

When searching for the right mattress to outfit a bunk bed, some new rules can come into play. We’re here to fill you in on this information before buying. Mattress type, thickness, and density are all factors that will lead you to the mattress that best suits your bunk.

Mattress Type: Innerspring mattress or foam? Although the former is not seen as often these days, it’s still a solid option that might work best in your situation. Some people like a little spring and firm support. If you’re opting for foam, keep in mind that there are many different types out there and they can be quite different from one another. Gel memory foam will fit you like a glove, while a base foam solely helps with density and support. 

Thickness: This factor is the most important of them all. You’ll need to make sure that the ratio between the height of your bunk bed’s guard rails, the thickness of your mattress, and the space from the ceiling is balanced. If the thickness is overlooked, injuries may prevail. 

Density: Considering firmness is about considering what’s most comfortable for you. A softer density will give you a cushy sleep; whereas, a firmer option will provide you with a strong base of support.


Bunk bed mattresses are a different ball game. With that said, the same priorities still apply; comfort, safety, and durability should all be non-negotiable. By reading this list, we hope you’ve gotten a little closer to understanding which bunk bed mattress fits your frame best.
