The Kiwi Organic Bunk Bed Mattress has earned the top organic certifications in the mattress industry including: GOTS Certified Organic (CU1015248), GOLS Certified Organic (CU 865932), GreenGuard Gold Certified by UL Labs, and MadeSafe® Certified. Learn more about our certifications here.


The Kiwi Organic Bunk Bed Mattress is crafted with high-quality organic and eco-friendly materials, sustainably harvested from our suppliers. It features 100% organic GOTS-certified wool and cotton, making the mattress cover and the top layers naturally breathable to help maintain a cool body temperature during the night. A supportive 2-inch layer of GOTS-certified organic and OEKO-TEX certified dunlop latex completes the comfort layers of this eco-friendly mattress.


Our custom made pocketed coil spring system is made in our Illinois factory and is easily one of the most durable and supportive low-profile spring systems available. The Kiwi Organic Bunk Bed Mattress incorporates a six-inch innerspring (compared to an 8-inch innerspring in our standard Kiwi Mattress). It is composed of up to 790 pocketed coils with added lumbar and edge support and is designed for key pressure point relief and overall comfort.


Hand button tufting is a time honored technique usually only found in luxury mattresses with many benefits including contributing to the overall durability of our mattresses and eliminates the need for toxic adhesives. The buttons are tied to cords that secure the layers of the mattress together, preventing the mattress layers from shifting or bunching and helping the mattress maintain its structural integrity over a longer period, reducing the risk of sagging or lumps.


The Kiwi Organic Bunk Bed Mattress is hypoallergenic and free from harmful chemicals, flame retardants and fiberglass, making it an ideal choice for individuals with allergies or sensitivities. To further ensure your safety, the mattress is MadeSafe® certified, guaranteeing that it contains no known harmful toxins.


The firmness ranking of the Kiwi Organic Bunk Bed Mattress is medium-firm. It is recommended for all body types, as well as stomach, back and side sleepers and can support any full sized adult.


The Kiwi Organic Bunk Bed Mattress is designed for kids’ rooms and is specifically sized for bunk beds and trundle beds. However it will fully support adults, making it a great option for growing teens and for any parent that sometimes falls asleep while reading to or snuggling with their child.


Part of making a mattress sustainable is ensuring that it is built to last. Each mattress comes with a 20-Year Warranty and a 365 Night Sleep Trial.


Organic materials like organic cotton, wool and latex have been shown to contribute to a more sustainable future because they are harvested without harmful pesticides, chemicals and energy-rich processes. Our mattresses are further certified by GreenGuard Gold and MadeSafe® to ensure their safety and sustainability.


Kiwi Bunk Bed Mattress can be placed on any bunk bed or trundle bed with a manufacturer’s recommendation of a mattress that is 8-inches or greater in height. This mattress will also work on any traditional foundation, solid platform bed, or platform bed with slats that are no more than 3.5 inches apart. This mattress can also be used on an adjustable bed base.

We recommend using a mattress protector to protect the terms of your warranty and to keep your mattress clean. Have a spill or accident that needs to be cleaned? Read our guide to cleaning your mattress here.
