Last Updated on

Nook Sleep smashes it out of the park when it comes to aesthetics. Their Pebble crib mattresses are visual joy, giving design-minded parents a bit of reprieve from all the primary-colored kid stuff in their lives. But what about safety – both human and environmental? Can the Nook Pebble Lite offer good looks, great function, AND a toxin-free sleep? We dug into the details to find out.

Introducing the Nook Pebble Lite Breathable Crib Mattress

The Pebble Lite Eco Friendly is Nook’s most breathable crib mattress. As with all Nook Sleep crib mattresses, it has a distinctive and beautiful Pebble cover, which will look like a million bucks in your baby’s nursery.

And according to Nook, it will also help keep your baby safe and cool.

“The asymmetrical pebble pattern increases air circulation over, around and through the mattress cover. Air travels through the valleys between the Pebbles making a more breathable sleep space for infants.”

Besides creating airflow on the surface of the mattress with the gorgeous cover, Nook achieves breathability by layering certified non-toxic foam with woven PETE (recycled water bottles) under the cover.

The Nook Sleep Pebble Lite is a breathable crib mattress made from recycled PETE bottles and CertiPUR-US® certified non-toxic foam. The inner mattress is covered in the unique Nook Pebble wrap, available in 5 gorgeous colors and crib-ready, not requiring any sheets! The wrap is machine-washable and made from cotton, moisture-wicking eucalyptus fiber, and zinc, to discourage mold, mildew, and mites. It measures 53” x 28” x 4” (on the larger end of a standard USA crib size) and weighs 17 pounds. The mattress is 2-stage, good for infants and toddlers, and has a number of certifications to assure you it is non-toxic and safe. Nook offers a 100 night trial to continental US customers, meaning there’s no risk to giving the Nook Pebble Lite a try!

What’s Inside the Nook Sleep Pebble Lite Crib Mattress?

CertiPUR-US® Foam

Both the Nook Pebble Lite and the Nook Pebble Air use CertiPUR-US® Foam in their mattresses. 

I call CertiPUR-US® foam “made without foam,” because it’s made without all kinds of nasty chemicals.

Buying CertiPUR-US® certified foam products is like a security blanket for parents. You know it’s free from many (although not all) of the harmful chemicals commonly used in conventional foam.  

Specifically, foam with the CertiPUR-US® certification is made without:

  • Ozone depleters.
  • All toxic flame retardants. CertiPUR-US® requires foam to be free from PBDEs, TDCPP and TCEP (”Tris”). However, Nook is transparent about the fact they don’t use any chemical flame retardants.
  • Mercury, lead, and other heavy metals.
  • Formaldehyde.
  • Phthalates regulated by the Consumer Product Safety Commission.

CertiPUR-US® certified foam also has to emit less than 0.5 parts per million Volatile Organic Compounds (VOCs).

Recycled PETE Bottles for Breathability

Admittedly, breathable plastic sounds like a bit of an oxymoron, but Nook seems to have pulled it off. 

The Nook Pebble Lite combines CertiPUR-US® foam with recycled Polyethylene Terephthalate (PET or PETE).

Even if Polyethylene Terephthalate sounds intimidating, I can assure you you’re familiar with this material. PET or PETE is a food-grade plastic. You’ll know it in its most common form: plastic soda bottles. 

Nook uses recycled bottles in their mattresses. This is a nice bonus for the earth, giving some empty bottles a chance to be useful for longer than the time it takes us to sip our Cokes.  

According to Nook Sleep:

“PETE is BPA-Free water bottle plastic that has been repurposed to create the lightweight, ultra-firm and extremely breathable side of the Pebble Lite … In addition to being non-toxic and safe, it is also responsibly reused in this eco-friendly mattress option.”

What About the Cover?

All Nook Pebble mattresses use a crib-ready cover (wrap in Nook speak). They’re all made of eucalyptus fiber, organic cotton, an organic cotton and non-toxic poly blend, and zinc, with a nylon zipper. 

You can use the Nook Lite without sheets. Because of this, Nook wanted to be sure it could stand up to gross, messy babies. They made a lot of their textile decisions around this.

The organic cotton is soft for your kiddo’s skin, the eucalyptus fiber helps to wick moisture away from your baby, and the zinc is used as an antimicrobial agent.

Is the Nook Pebble Lite Non-Toxic?

Fire Retardants in the Nook Pebble Lite

Nook doesn’t use chemical fire retardants in their products. Instead, they rely on inherently fire retardant materials (coconut coir, wool, etc). Or they use non-toxic fire barriers.

The Pebble Lite has a non-toxic fire barrier.

Now, unfortunately, Nook doesn’t provide a lot of information about this fire barrier. Throughout their website, they describe it as a “Non-Toxic Freudenberg Fire Barrier.”

We interpret this to mean Nook’s chosen fire barrier is proprietary to Freudenberg.

Certainly, I’d rather have more info about the fire retardant system in the Nook Pebble Lite. However, Nook’s independent certifications also help assure this truly is a non-toxic crib mattress.

Independent Certifications

In addition to using CertiPUR-US® Foam, Nook has certifications from GREENGUARD GOLD, the Global Organic Textile Standard, Oeko-Tex®, bluesign®, and more.

  • Nook’s products meet GREENGUARD Gold standards for the lowest chemical emissions checked for.  
  • Global Organic Textile Standard means Nook products need to contain at least 95% organic fiber, along with other stringent requirements. Products can’t be treated with bleach, formaldehyde or other toxic substances, they must use non-toxic dyes, and they need to manufacture in facilities applying strict social and environmental standards.
  • Oeko-Tex® certified textiles certified to be free from chemicals and safe for human use. Nook doesn’t specify which of the materials it uses meet Oeko-Tex® Standard 100.
  • Nook sources from FSC certified forests. It’s unclear if this is related to packaging or the eucalyptus fiber.
  • Nook follows the bluesign® system for sustainable textile production. This ensures harmful substances aren’t used in the manufacturing process, and ensures production is safe for people and the environment.

Local Economy Supporting

Part of Nook’s thing is supporting their local economy. In this case, that means the USA. The company sources a lot from US producers and manufacturers. This is good news for the environment, because it cuts down on greenhouse gases for shipping, and the US *may* have more stringent environmental standards than some manufacturing powerhouse countries.

With the Nook Lite, Nook uses US-made and tested CertiPUR-US® foam and US-made zippers. The company sources packaging for the mattress from Los Angeles.
