Best Bunk Bed Mattresses (Twin & Twin XL)

Bunk beds aren't just made for children and can be a perfect way to host multiple adult guests. If you want an environmentally friendly bed for your bunk bed, the Natural Bliss is a great option. The 8-inch PlushBeds Natural Bliss Mattress is a thin mattress that will fit your bunk bed while providing enough body support for adults.

Unlike other PlushBeds models, which include a layer of wool under the cover, the Natural Bliss features a plant-based, proprietary fire barrier. Each variant of the PlushBeds Natural Bliss comes with the same organic cotton cover, but the specific configuration of comfort and support layers varies by firmness and thickness. All the mattresses use a 6-inch base of natural Dunlop latex, which offers a sturdier and more supportive feeling. 

As for the comfort layers, they vary by firmness and thickness. The 8-inch model features a 2-inch comfort layer made of Talalay latex. Compared to Dunlop, Talalay latex is springier and more responsive, enabling your mattress to offer more pressure relief and conforming. 

The PlushBeds Natural Bliss ships free anywhere in the contiguous U.S. and is available in Full, Twin XL, and Twin sizes. It should be compatible with most child-friendly bed frames and bunk beds. It comes with a 100-night sleep trial and a 25-year warranty. 

If you want a cooling, affordable mattress for your bunk bed frame, the GhostBed Classic is worth a look. It consists of three dense, supportive memory foam and latex layers to promote growth and development. An 11-inch profile makes it compatible with standard bed frames and bunk beds.

The GhostBed Classic begins with a stretchy polyester material quilted into a thin and breathable cover, followed by a 1.5-inch comfort layer of aerated latex foam that's responsive and ventilated to keep your kids cool throughout the night. Next, you'll find another 2-inch layer of gel memory foam that protects sleepers from night sweats and stickiness. What's more, it adds more pressure relief to the sleep surface. A high-density foam base completes the design. This 7.5-inch helps keep your mattress firm, steady, and stable. 

GhostBed provides free ground shipping throughout the contiguous United States. The Classic Mattress comes with a 101-night sleep trial period and a 25-year limited warranty.

Kids and preteens often need a sleep surface that supports and cushions their bodies equally. This ensures proper growth and development, not to mention night-to-night comfort after they have ditched their toddler bed. The Amerisleep AS1 has many features that make it a viable option for children in the preteen stage. For starters, it has a low profile, a firm feel with gentle cushioning, and a breathable top layer that won't trap heat. Plus, its firm feel limits sinkage, which should keep your kid's body on an even plane. 

The Amerisleep AS1 features a two-layer design starting with a top layer of Bio-Pur foam that's designed to be more responsive and breathable than traditional memory foam. This material also offers some contouring to the body and enables sleepers to sink a little bit for pressure relief.
