Mattress Review: Nook Pebble Air Crib Mattress


The Nook Pebble Air crib is the Nook Pebble mattress with the greatest bang for the buck for budget-conscious parents. You may feel secure putting your young one to sleep on the Nook Air each night because it is made safely. The Pebble Air is the most inexpensive choice in Nook’s Pebble crib mattress line, as well as Nook Sleep’s lightest crib mattress.

Breathable & Lightweight Crib Mattress – Nook Pebble Air Crib Mattress

The Nook Sleep Pebble Air baby mattress is the company’s lightest crib mattress. This mattress, which is about the same weight as a baby (7 pounds), won’t break your back… or your pocketbook.

When compared to the Nook Pebble Lite ($299), Nook Dream Cotton ($299), and Nook Pebble Pure ($419), the Pebble Air ($209) is a bargain, making it an excellent choice for parents who wish to be “toxin-free” while staying within their budget.

The Air, like the Nook Lite, is a two-stage crib mattress. The Nook Pebble Air is fully composed of approved foam, unlike the Lite, which is made of certified foam and recycled PETE bottles.

Yes, the Air is both light and inexpensive. Yes, the Nook’s signature pebble cover is still included (you can choose from three colors).

The pebble cover, like with other Nook Sleep products, is what makes this mattress “crib ready.” You don’t need to use sheets if you put your infant to sleep straight on the Pebble.

The pebble pattern not only contributes to the beauty of the mattress, but it also improves its functioning. It helps air move over and through the mattress, according to Nook, making your child’s sleeping area more breathable.

Nook Sleep Pebble Air Crib Mattress

The Nook Pebble Air is a breathable and lightweight crib mattress made primarily from CertiPUR-US® certified foam. Covered in the distinctive Nook Pebble wrap (available in 3 gorgeous colors), the Nook Pebble Air can be used with or without sheets and is machine washable. The crib mattress cover is made from cotton, eucalyptus fibre, and zinc, making it naturally excellent at wicking moisture and keeping mold and mites away. It measures 53” x 28” x 4” (which fits a US standard-size USA) and weighs just 7 pounds. The Pebble Air is a 2-stage mattress, offering a firmer side for infants and a slightly plusher side for toddlers. It is GREENGUARD Gold certified (among others), giving you extra confidence that it’s a safe option for your baby. If you’re a continental US customer, you can also take advantage of Nook’s 100-night trial. You may also take advantage of Nook’s 100-night trial if you live in the continental United States.

What Materials Does The Nook Sleep Pebble Air Crib Mattress Made From

Two of Nook’s crib mattress types, the Nook Pebble Lite and the Nook Pebble Air, are made of foam. CertiPUR-US® certified foam is used in both of these mattresses.

In a nutshell, what does this mean? It’s called “Made Without” foam since it’s free of a number of chemicals that are frequently found in foam.

This certification does not ensure that the foam is free of all hazardous compounds, but it does guarantee that it is free of the ones mentioned below.

It’s worth mentioning that Nook uses no chemical flame retardants.

  • Ozone depleters are substances that deplete the ozone layer.
  • The Globally Harmonized System (GHS) has classified fire retardants as chemicals that may cause cancer, genetic abnormalities, or harm to fertility or the unborn child. CertiPUR-US® foam must be free of PBDEs, TDCPP, and TCEP (sometimes known as “Tris”).
  • Heavy metals such as mercury, lead, and other heavy metals
  • Formaldehyde.
  • The Consumer Product Safety Commission regulates phthalates.

Furthermore, it indicates that the foam produces fewer than 0.5 parts per million of VOC’s (VOC’s).

Dual Firmness Foam

The Nook Pebble Air is a two-stage crib mattress, with one side firmer for babies and the other plusher for toddlers.

Customers have previously had difficulty determining which side is which.

Thankfully, Nook has solved this issue by putting a little tag to the mattress that indicates which side is for infants.


The Air comes with a Pebble wrap, much like the rest of Nook’s Pebble crib mattresses (wrap is what Nook calls their mattress covers).

The air wrap is built with the same high-quality materials as the other pebble mattresses: eucalyptus fibre, organic cotton, an organic cotton-poly mix, zinc, and a nylon zipper.

Eucalyptus fibre may sound strange for a mattress cover, but it helps to drain moisture away from your baby’s skin, according to Nook. Zinc is an antibacterial substance.

Fire Retardants in the Nook Pebble Air

Nook is adamant about avoiding utilizing chemical fire retardants in any of their goods. They’ll have to come up with additional techniques to ensure the items aren’t combustible to fulfil federal flammability regulations.

Nook employs a “non-toxic fire barrier” in the Pebble Air. We thought the language was a little unclear for a firm that prides itself on transparency. Thankfully, Nook contacted us to explain what this implies (our emphasis in bold):

Our goal with FR is to mirror the natural fire barrier capabilities of wool using a combination of natural and non-toxic man-made materials. The ideal combination of genetically enhanced materials such as rayon and silica offer the highly desirable FR properties, which essentially means that the fire protection is naturally part of the polymer backbone and can never be worn or washed away. Rayon is regenerated cellulose fibre, while silica occurs when mineral quartz, sandstone and other rocks combine. The non-toxic fire barrier is free from carcinogenic chemicals and harsh toxins found in most other fire retardants. So the long and short is that we have done our research and we have checked the boxes and the FR Fire Barrier is not only safe and healthy, but it will stand the test of time as well.

The line “can never be worn or washed away” was bolded since one of the major issues with chemical fire retardants is that they detach from the polyurethane foam to which they’re commonly applied over time, resulting in household dust.

In addition to Nook’s statement above about their non-toxic fire barrier and their overall commitment to not utilizing chemical fire retardants (available on their website), Nook has a long list of independent certifications that show the mattress’s worth as a non-toxic baby mattress.

We’re very secure about putting our infants to sleep on this kind of crib mattress when we look at it all together.

We already covered Nook’s foam, which is CertiPUR-US® certified. Beyond this, Nook products hold a range of certifications, including:

  • Global Organic Textile Standard
  • Oeko-Tex® Standard 100
  • FSC certification
  • bluesign® system for sustainable textile production

Is It Breathable?

It seems like calling a crib mattress “the Air” and not making it breathable would be a major mistake.

The Pebble Air, on the other hand, is one of Nook’s breathable crib mattresses.

Nook claims that:

Considered the best light weight option in its class, the Air core packs a major punch when it comes to breathability. Strategically placed open air channels within the mattress core allows oxygen to flow freely. The dual-sided construction is ideal for infant and toddler sleep.

What We Love About The Nook Air

Nook is a huge supporter of the local economy, which is good for both jobs and the environment. The foam in the Pebble Air crib mattress is produced and tested in the United States, as are the zippers.
It’s very light, weighing only 7 pounds (less than some infants!).
Because of the dual-sided hardness, you’ll be able to use this mattress for many years – long into your child’s pre-school years.
The mattress comes with a limited lifetime guarantee (and all other Nook crib mattresses).
The washable Pebble wrap has a beautiful and useful design. The Air wrap is available in three distinct colors.
There are no chemical fire retardants in the foam used in the mattress, unlike typical polyurethane foam.
Multiple independent certificates provide assurance that this mattress is genuinely safe and non-toxic for your young one! We enjoy seeing the Greenguard Gold accreditation since it implies we won’t have to worry about hazardous VOC’s off-gassing in our baby’s nursery.

Things The Nook Air Could Do Better At

The biggest issue we have with the Nook Pebble Air (and the Nook Pebble Lite) is the absence of information on their website concerning the “non-toxic fire barrier.” We appreciate that this is most likely for commercial reasons, however it appears like Nook glosses over the issue on their website. (We’ve removed this from the record because Nook contacted us to clarify more about the FR barrier!)
