The Naturepedic Organic Cotton Classic Lightweight 150 crib mattress has a “U.S.-grown organic cotton filling” and their WaveSupport system made with food-grade polyethylene plastic, as well as a polyethylene waterproof surface. This mattress is much lighter (around 8 pounds) than their classic innerspring crib mattress (around 21 pounds) and is free of vinyl/PVC, phthalates, lead, and antimicrobial biocides.

What we like

Naturepedic’s Lightweight version of its Classic crib mattress is a little cheaper and a lot lighter, all without compromising firmness or safety. The lower weight makes for much easier middle-of-the-night crib changes! (This is much harder with a heavy and floppy latex crib mattress)

Naturepedic offers two lightweight options:

  • A one-stage crib mattress
  • A two-stage crib mattress that can see your baby through toddlerhood.

I strongly suggest choosing the two-stage model as this is more sustainable and budget-friendly in the long-run.

These lightweight mattresses have reinforced edges and square corners to properly fit standard size cribs. This mattress also fits toddler beds and day beds.

This is a wool-free crib mattress, making it vegan-friendly.

Like most Naturepedic crib mattresses, this one has a waterproof cover comprising food-grade low-density polyethylene (LDPE). This is less toxic and more eco-friendly than polyester and will biodegrade at end of life.


There are few downsides to this crib mattress. If pushed, I’d say that the slightly heavier Classic crib mattress which contains innerspring coils may be a tad more robust (and bouncier) overall. If you suspect you’ll have a larger baby or intend to use this mattress through to late toddlerhood, the innerspring model may be a better bet.

In fact, I’d even suggest going for the Breathable or Breathable Ultra models from Naturepedic. These have a far higher coil count and more edge reinforcement. So, while none of these crib mattresses are meant for adults to lie on, the higher coil count models will stand up better to the occasional co-sleeping arrangement.

Great customer service!

Naturepedic has a strong reputation for making high quality mattresses both for adults and children. It offers excellent customer service too and is typically very responsive if anything does go wrong.

Naturepedic vs. the competition

Two things really set Naturepedic’s Lightweight Cotton Classic Crib Mattresses apart from other eco-friendly, non-toxic crib mattresses:

  • The built-in non-toxic waterproof cover
  • The fact it weighs just 10 or 11 lb.

This means that if you can lift your newborn, you can probably lift this mattress.


If you’re looking for an eco-friendly non-toxic and lightweight crib mattress with an in-built waterproof cover, Naturepedic’s Organic Cotton Lightweight crib mattress is your best bet.

Naturepedic’s quilted model isn’t waterproof, so be careful to choose the right mattress!

For most other crib mattresses I recommend at LeafScore, you’ll need to use wool puddle pads and/or a waterproof crib mattress cover or pad.

Wool and fire resistance

If you’d rather not have wool in your crib mattress, Naturepedic offers some of the best wool-free options.

In contrast, OMI, Soaring Heart, Sleep Lily, and Savvy Rest all include wool in their crib mattresses. Essentia is another good option for a wool-free crib mattress, while Lullaby Earth offers a decent wool-free crib mattress made with recycled polyester and polyethylene.


Naturepedic is an excellent mid-price option for an eco-friendly and non-toxic crib mattress. Because it already has a waterproof cover, Naturepedic’s Organic Cotton Classic and Lightweight Classic end up costing less overall than slightly cheaper mattresses without waterproofing built-in (such as My Green Mattress; see our review).

Lullaby Earth offers a marginally less expensive version of the Naturepedic lightweight mattress, made instead with recycled polyester and polyethylene. It has some good eco-certifications, but if you’re going to spend more than $200 on a crib mattress, I strongly suggest going with My Green Mattress or Naturepedic instead.

If you want a lightweight crib mattress, the Naturepedic Lightweight is your best option.

Non-toxic and eco-friendly credentials

Naturepedic boasts all the key green certifications I expect from a crib mattress and has long led the way, pushing the industry as a whole to do better.

The Naturepedic crib mattresses were the first to be EWG Verified. This certification comes from the Environmental Working Group and means you can rest assured that Naturepedic:

  1. Discloses all materials and ingredients
  2. Only use safer materials than don’t off-gas harmful VOCs
  3. Don’t use any PFAS, harmful chemical flame retardants, or fiberglass
  4. Don’t use polyurethane foam or PVC.

Naturepedic was also one of the first crib mattress companies to attain MadeSafe certification, as well as maintaining GOTS certification for many years running.

Other things you won’t find in a Naturepedic Crib mattress include:

  • Antibacterial treatments
  • Glues or adhesives
  • GMO materials.


Naturepedic crib mattresses are a fairly standard size, but if you happen to have an ever so slightly larger crib than usual, you may want to avoid this mattress and choose something else.


Because Naturepedic’s Classic Crib Mattress is a tiny bit narrower and shorter than some others. I’m talking a quarter to three-quarters of an inch in width and just a few eights of an inch difference in length, though, so chance are your mattress will fit just fine, without any safety concerns.

Soaring Heart crib mattresses tend to be the biggest of the bunch, but they’re much thinner, at just 3.5 inches deep versus the standard 6-inch depth.

Both Savvy Rest and My Green Mattress crib mattresses are a tiny bit wider and longer than Naturepedic’s crib mattresses.

For comparison, here are the mattresses listed from largest to smallest in terms of width and length:

  • Soaring Heart – 28 5/8” x 52 3/8” x 3 ½ “
  • Sleep Lily – 28” x 52” x 6”
  • NaturalMat – 28” x 52” x 6”
  • Savvy Baby – 27 ½” x 52” x 6
  • My Green Mattress – 27 1/4″ x 52″ x 6″ 
  • Naturepedic – 27 ¼” x 51 5/8” x 6” 
  • Lullaby Earth – 27 ¼” x 51 5/8” x 6”.

Warranty and refunds

All Naturepedic crib mattresses come with a 100-night trial and free returns, assuming you buy directly from the company. You have to pay all shipping costs (including outbound costs associated with any promotions), however. Naturepedic offers a lifetime warranty on crib mattresses though.

My Green Mattress has a similar 100-night sleep trial. If you don’t want to keep the mattress after your 100 nights, My Green Mattress will work with you to donate it to a local charity and then refund your money. 

Savvy Rest doesn’t do returns at all.

Final thoughts

Naturepedic is our top choice for safe, non-toxic, and eco-friendly crib mattresses. While I prefer the higher coil count Breathable innerspring version (view on Naturepedic), the lightweight two-stage model is a great choice too, especially if you’re keen on a super light mattress with built-in waterproofing.

  1. We just purchased this mattress and it ran a little small. Have you looked into the Avocado latex crib mattress? Dimensions seem to fit our crib better and runs around the same price. Curious for your thoughts on it…

    • Hi Zack,


      I haven’t reviewed the Avocado crib mattress (yet), but a quick look suggests it would be a great choice. It’s made with natural latex, individually cotton-wrapped coils, and flax and coir pads to structure, plus a layer of wool as a natural fire barrier. I also like that they’ve designed it for longevity (always good for sustainability!) by having a side that is firmer for younger infants and a bit softer for the toddler years, with easy labelling for sleep-deprived parents!

      If you ended up going with the Avocado mattress, let me know how it’s working out for you.

      All the best,
