What makes the Sleepout Crib Mattress different?
A better mattress — made from materials you recognize
Everyone deserves a good night’s rest — especially our little ones. That’s why we’ve crafted our Sleepout Crib Mattress to be safe, breathable, long-lasting, and comfortable — from familiar materials and without harmful substances.
It’s a 100% breathable mattress made from a blend of cotton, wool, and polyester fibres. The high-density core is thermo-bonded, with no chemical flame retardants, petroleum-based foams, fiberglass, or adhesives to bind the layers. The cotton and wool fibres carry all the benefits of their organic properties, so it naturally sleeps cool. And the high-density core delivers the breathable support growing bodies need.
We chose a breathable bamboo outer cover because of its softness, temperature-regulating capabilities, natural stain resistance, hypo-allergenic properties, and long-term durability. It’s even GREENGUARD GOLD® Certified — a standard of safety so high only mattresses with absolutely zero toxins can qualify.
How it's made

Why we made this
When we started Sleepout, we were surprised by the problems with so many home & baby products. We realized a few important things while designing our mattress.
While it's cheaper for companies to condense mattresses for shipping, inconsistencies mean children could be harmed while sleeping on a mattress that's not fully expanded. We also learned that foam mattresses often contain fibreglass and polyurethane, which offgases VOCs that can be harmful to developing children.
That's why we developed our natural crib mattress from materials you recognize. It's free of toxins, precisely crafter, and never compressed for ultimate safety. So your little one can get a better sleep with the natural support they need.

Reasons to love the Sleepout Crib Mattress
FAQ
What is the mattress made of?
The breathable, hypoallergenic cover is made from bamboo, while the mattress is made from a 5" thermo-bonded core made from a blend of natural cotton, wool, & polyester fibres (the polyester fibres bond the cotton and wool core together with just heat–no chemicals–to give it strength and shape).
What size is it / what are the specs?
Each Sleepout Crib Mattress is 5.5” thick, and measures 52" x 28" x 5.5” with a weight of 14 lbs.
Is it waterproof?
The bamboo cover is both temperature regulating and water resistant, to keep your little ones cool and sweat-free during the night. However, it is not waterproof. For toddler beds and concerns about accidents, we recommend adding a mattress cover for extra protection.
How can I clean it?
The bamboo cover is machine-washable and easy to remove (just look for the hidden zipper and unzip the cover from the core). As a bonus, it’s quick to air dry!
What does “all natural materials” mean?
Our mattresses are made from clean materials without any additives, which means zero latex, adhesives, or flame retardants (or other chemicals like PVC) in the mattress at all. Thermo-bonding means that heat helps the fibres fuse, so there is no need for any additional materials or adhesive - and then the bamboo covers are fitted around the core.
Where is it made?
Our mattress is made by a family-owned manufacturer in the US and Canada, and the bamboo cover is imported from Europe.
Is there an age limit?
Sleepout Crib Mattress will last as long as your littles will use it! Our manufacturer is offering an incredible 15-year warranty, so you can use your Sleepout Crib Mattress for many years (and even for multiple siblings!)
What is the warranty?
Our manufacturer is offering a 15-year warranty on every Crib Mattress.
What makes Sleepout’s Crib Mattress different?
Our Crib Mattresses are made with all-natural materials, and zero additives, chemicals, plastics, or metals. Unlike most Crib Mattresses, ours ship fully expanded, and are never compressed, for ultimate safety. The cotton and wool fibres carry all the benefits from their organic properties, so it naturally sleeps cool. And the high-density core delivers the breathable support growing bodies need, with the firmness recommended by the American Association of Pediatrics. The breathable bamboo cover and core also helps baby stay cool, and lower the risk of suffocation.
How do I know that this is a safe choice for my family?
We've done extensive testing on the products to ensure no chemicals, off-gassing, or anything similar that could harm your family—like all of our products, Sleepout Crib Mattresses are OEKO-TEX®, SGS®, and Greenguard® certified non-toxic.
