The Organic Breathable Ultra 2-Stage Baby Crib Mattress combines breathability and waterproofing for a safer, healthier and more hygienic crib mattress design. The mattress starts with a firm, flat waterproof surface made from non-GMO sugarcane that is so pure, it actually meets food contact standards and easily wipes clean. This approach protects the inside of the mattress from urine, spit-up, and other messes. We then add a 3-dimensional cover with a soft organic cotton surface for increased airflow. This unique cover creates a breathable space under the baby which improves temperature regulation and allows the baby to breathe right through it if necessary. Finally, the flexible 2-stage design allows the mattress to grow with your child for years to come. Features organic cotton fabric & filling throughout and passes all federal and state flammability standards without any fire retardant chemicals or flame barriers whatsoever. Get all the safety features you need, including breathability, while maintaining a healthier, more hygienic, organic crib mattress design.

What is a "breathable crib mattress"?

A mattress that allows your baby to breathe through the surface in case he/she rolls over to be face down. It also makes the mattress more comfortable by allowing airflow between the baby and mattress which results in a cooler and less sweaty sleep.

How does Naturepedic do breathability differently than everybody else?

Naturepedic breathable baby mattresses come with a breathable layer on the surface of the mattress rather than making the whole mattress breathable all the way through (including the interior of the mattress). The breathable layer is removable, machine washable, and doubles as a mattress protector since it has a waterproof backing.

Why is the Naturepedic design better than a crib mattress that is breathable all the way through?

We believe that breathable crib mattresses that are breathable all the way through pose a safety risk to the baby without any added breathability benefit. If liquid (think pee, poop, spit-up, milk, etc.) get into the interior of the mattress, it is virtually impossible to clean. This will lead to mold growth which can contaminate the air your baby breathes in. Some designs allow you to wash the mattress core in the shower using cold water only. However, this is highly impractical for several reasons. Drying could take several hours and newborns sleep every 90 minutes, so your baby could get stuck with nowhere to sleep. Additionally, that kind of breathable crib mattress is made with phosphate flame retardants, which are known to be toxic.

Naturepedic breathable crib mattresses have a waterproof core that is covered with our exclusive food-grade surface made from non-GMO sugarcane. The breathable layer is on the outside of the waterproof core so you get the best of both worlds; a breathable surface plus a mattress core that will stay dry and safe.

Is there an official rating for breathable crib mattresses?

There is an official test for crib mattress breathability which is administered by a third party lab. In the test, a device is placed on the mattress surface and mimics a baby breathing face straight down. The device measures the air resistance to determine if the surface is truly breathable or not. The score is between 0 and 100 with a lower score being better. Any score lower than a 16 is a passing score, meaning that a baby can breathe through the surface indefinitely. Naturepedic breathable crib mattresses scored a 2, which is about the best you can get. We have tested other "breathable" crib mattresses on the market, including the ones that are open to the inside, and none score lower than a 2 with most of them scoring higher.

The Naturepedic design provides the highest level of breathability without compromising on a quality crib mattress underneath.

Is "organic" or "breathable" more important?

They are both important. However, if the mattress is breathable, the "organic" part is even more important. If babies can breathe "into" the mattress, we need to be asking how safe is the air quality of what they are breathing in? Using organic non-toxic materials guarantees that there will be no offgassing from flame retardants or other chemicals, whether inside or outside the mattress. Naturepedic is the only manufacturer that makes crib mattresses that are certified organic, breathable, and waterproof.

What is the difference between lightweight and innerspring?

Our lightweight organic crib mattresses are made with our patented WaveSupport technology, which is is both supportive and extremely lightweight. A lightweight crib mattress makes changing sheets a lot easier, as lifting a crib mattress out of a crib can be cumbersome. The mattress core is made from food grade polyethylene, a safer, non-toxic material.

The innerspring version is for those who want the ultimate in support and durability. The innerspring has 252 coils, which is among the highest coil count in the industry. It disperses the weight of the baby over more coils, reducing pressure points. It also has a heavy-duty border rod for extra support around the perimeter. If you plan to use the crib mattress in a toddler bed, where an adult may sit on the edge, the innerspring may be a better choice.

What is the difference between the Breathable and Breathable Ultra Organic Baby Crib Mattresses?

While both models meet the highest standards for breathability, there are some differences. The Breathable Organic Baby Crib Mattress has a waterproof backing on the removable cover, which prevents liquids from reaching the mattress. On the other hand, the Breathable Ultra comes with a separate flat waterproof pad that is meant to go between the mattress and the cover. The flat waterproof pad is also great for traveling, as you can use it on just about any surface where you want to put your baby down. The Breathable Ultra also has a thicker breathable layer for extra airflow as well as an upgraded, more luxurious organic-cotton surface.

Do I need a waterproof mattress protector?

No. The Breathable Ultra Organic Baby Crib Mattress comes with a waterproof pad that goes between the mattress core and the breathable layer. It is removable and machine washable. For added convenience, buy an extra Breathable Ultra Organic Mattress Cover so you can have a backup when one is in the wash.

Will this crib mattress fit my crib?

All full size cribs in the United States are a standard size. As long as you have a standard crib (roughly 52" x 28"), Naturepedic crib mattresses should fit.

Should I use a sheet with Naturepedic Breathable Organic crib mattresses?

We recommend using a sheet with all of our crib mattresses. You can launder your crib sheets without removing the breathable layer, which only needs to be laundered if there is a spill that leaks through the sheet. The breathable layer should be laundered every 1-2 weeks.

Will a sheet reduce the breathability of the mattress?

Most standard crib sheets allow enough airflow that the breathability will not be affected. You can test your sheets by making a seal with your mouth and trying to breathe through them. You should not feel a lot of resistance. Densely woven or coated fabrics may reduce breathability.

Is the breathable pad included?

Yes, the Breathable Ultra Organic Baby Crib Mattress comes with a breathable cover as well as a flat organic waterproof pad.

Can I buy extra breathable protector pads?

Yes, you can purchase additional Ultra Breathable Organic Mattress Covers here.

What is "2-Stage"?

"2-Stage" means the crib mattress has a firm side and a slightly softer side. For infants, use the firm side. Once the baby is approximately one year old, turn the mattress over for a more comfortable sleep surface. Both sides are firm enough to be safe for an infant.

How firm should a crib mattress be?

Most experts agree that crib mattresses should be very firm. This is sometimes surprising for new parents since it is counterintuitive. But it is actually safer.

Will Naturepedic baby mattresses fit a toddler bed?

Yes. Toddler beds are the same size as cribs. The only difference is that they are usually open on one side so your toddler can climb in and out.

What is the weight limit for the Organic Ultra Breathable Crib Mattress?

80 lbs for the lightweight version. 100 lbs for the innerspring version.
