Product Review: Newton Crib Mattress – Is It Worth It?

Updated on


Did you know that as many as 4,000 seemingly healthy babies unexpectedly die in the US due to SIDS (sudden infant death syndrome), accidental suffocation, or unknown causes? (1)

According to the FDA (US Food and Drug Administration), many of these deaths are due to babies rolling to their stomachs and suffocating on their mattresses, pillows, infant sleep positioners, or other items inside their cribs. (1)

To reduce the risk of suffocation, the FDA recommends making your baby sleep in a bare crib. Soft toys, pillows, blankets, quilts, comforters, and extra clothes should never be put inside their sleeping areas. (1)

So, in choosing a bassinet or crib mattress, make sure that it’s made of breathable material.

It costs more than most crib mattresses, but the Newton Crib Mattress is a breathable bed that can help reduce your baby’s suffocation risks while sleeping. Is it worth your money? Continue reading this review to find out.

Does Newton Mattress Reduce SIDS?

Newton Crib Mattress Reviews

Positive Reviews

We love the peace of mind knowing that the mattress is 100% breathable since we don’t want to worry about SIDS. We love that it’s easy to clean too—worth the extra money!” – Reviewer on Baby List.

I’m already so happy I have this mattress. She automatically became a face-planter and tummy sleeper. And I’m able to rest easy at night knowing she is on this mattress.” – Reviewer on Newton Baby.

Love this mattress. My son likes to sleep face down, so this gives me a little peace of mind. Also, he’s now sleeping almost 1.5 hours longer every night! I call that a win.” – Reviewer on Amazon.

Negative Reviews

So the reviews say it reeks of chemicals? I thought, ‘must have been a bad batch.’ Nope. THIS THING REEKS. I opened it up, and the smell hit me like I had walked into a Sherwin-Williams paint store.” – Reviewer on Amazon.

I am a bit disappointed by this expensive mattress. Long time spent reading and searching for a non-toxic mattress. And it smells so much that it is impossible to stay in the room. I don’t understand why only 1% of the reviews mention the smell. It is hard not to notice it.” – Reviewer on Amazon.

This mattress stinks. Like most of the parents who end up finding this mattress, I found it after weeks of research for the most breathable crib mattress on the market. Unfortunately, it has a terrible chemical smell that hits you as soon as you take it out of the box. The smell didn’t go away after airing it out. Every time I caught a whiff, I would get an instantaneous headache. The smell was not because of “off-gassing” or tight packaging.” – Reviewer on Amazon.


Newton Baby Crib Mattress FAQs

Is The New Baby Crib Mattress Organic?

This crib mattress isn’t organic, but it’s certified for low chemical emissions and no toxic VOCs.


Is The Newton Mattress Safe?

Made from natural materials with Greenguard Gold Certification, the crib mattresses are free from off-gassing, the scent of new products. (3)

While the “new” scent smells good, that could be due to toxic VOCs and other chemicals that can harm your little one.


Do Breathable Crib Mattresses Work?

Some parents who reviewed the product tested its breathability by putting their face down on the mattress. They were able to breathe even if their entire face was flat on the mattress.


Are Newton Mattresses Worth It?

Despite the high price tag, these mattresses can be worth your money. 

Newton crib mattresses are more expensive than regular brands. Tthe cheapest standard size can cost twice or thrice the price of other brands, while the waterproof version cost more.

You can even find other organic crib mattresses within the cheaper brands’ price range; although others also cost more.

Newton Baby markets its baby crib mattresses as breathable, low-chemical baby products that allow better sleep for your baby up to their toddler years. (2)

Some parents believe the price tag is too high, but others believe that the safety features could make the crib mattresses worth it because it gives them peace of mind.

Also, these baby products are washable, firm, and may last until your baby’s toddler years.


How Do I Know If The Mattress Is Firm Enough?

Some parents suggest testing the mattress firmness by putting household items about the same weight as your baby. Check if the item sinks on the mattress.


How Can I Wash This Crib Mattress?

You can wash all the parts of this mattress. But it’s best to wash the mattress core only on a seasonal basis or if your baby makes a really big mess.

If needed, wash the core under running water and shake the excess water off. Stand upright to dry. Place it in a well-ventilated area, but avoid direct sunlight. Don’t use heating elements for drying.

The mattress cover can be washed as often as you can, but only wash the encasement (second layer) when soiled.

Both the mattress cover and the encasement can be washed inside the washing machine. Don’t leave damp from the wash, and don’t hang dry. Use a low heat setting for tumbling dry.

If the natural Viscose material develops an odor, add ½ cup baking soda while washing.


Is The Newton Mattress Double Sided?

You can use both sides of the Newton mattress for infants and toddlers alike. The sides have the same firmness that may be ideal for both stages.

If you already have a crib mattress at home, you can add a Newton waterproof crib mattress pad to help make it breathable.

Newton Waterproof Crib Mattress Pad

The crib mattress pad has a TPU (thermoplastic polyurethane) waterproof lining, a universal fitted skirt, and two layers of breathable quilted spacer material.

This product is also Greenguard Gold Certified for your baby’s health.

You can also add this waterproof mattress pad to your non-waterproof Newtown crib mattress or opt to buy the waterproof mattress option.

But Newton Baby doesn’t recommend using the mattress pad until your little one is one year old to maximize the Newton crib mattress’s breathability benefits.
