This innerspring mattress offers four sizes that support bunk, platform, and trundle bed—so gone are the days of guesswork of finding the perfect bed fit. Naturepedic prioritizes safety and sustainability, with organic materials that reduce the environmental impact of synthetic pesticides and fertilizers. The materials are GOTS-, Made Safe-, and UL/GREEDGAURD-certified.

It’s also dual-sided and can support young sleepers through their growing years. One side is quilted, and the other has a smooth, waterproof surface. Depending on your child’s age and preference, simply flip the mattress over. At the core, an open innerspring design provides comfort, airflow, and temperature-regulation.

Mattress setup services are available, depending on your location. Though, if you prefer to set this mattress on your own, reviewers assure that the process is easy: simply take your mattress out of the box, remove the plastic cover, and let it expand into shape for a few hours.

Since this mattress successfully marries sustainability with support, reviewers say it’s a great bunk bed-friendly mattress overall. “The quality of the mattress is better than I expected for a top bunk mattress that needs to be thin. My son says that it is very comfortable,” one parent writes.

While most reviewers appreciate the waterproof protection this mattress provides, others give a reminder that the waterproof protection doesn’t extend to both mattress sides. To properly safe-guard your mattress, it may be helpful to add a waterproof mattress cover on top for an extra layer of protection.
