Made using entirely organic materials which naturally help regulate airflow and body temperature, this mattress can be used by newborns, older infants, and toddlers. This mattress is not recommended for use with a wire base, however, and is best suited to a slatted or flat crib base.

Naturalmat is a decent option for a crib mattress, especially if you’re in the UK. Here’s our unbiased review of the Naturalmat Quilted Coco Crib Mattress. Spoiler alert: It’s not our top choice for an eco-friendly, non-toxic crib mattress.

In 2001, Naturalmat was the first US company to make a crib mattress that met all British Standards without using any glues, chemical fire retardants or synthetics of any kind. The Coco Mat Crib Mattress was also the first UK-based company to use certified organic coconut coir in its mattresses, and as of 2023, Naturalmat is the UK’s first B Corp mattress maker.

Naturalmat now makes three crib mattresses (plus a Stokke oval crib mattress). All three models include organic coconut coir, organic wool, and conventional cotton. Two also include natural latex that isn’t certified organic. One includes a horsehair core with mohair and is decidedly not vegan-friendly. It’s also very expensive at $700.

Our review here is for the original Quilted Coco Mat Crib Mattress only.

Features of the Naturalmat Coco Crib Mattress

The Naturalmat Coco Crib Mattress appears to be similar in construction to the Avocado Organic Crib Mattress. However, it doesn’t carry the same warranty, certifications, and transparency over design and materials. The Naturalmat mattress is also more expensive.

Overall, the design of the Naturalmat mattress looks robust, with a coconut coir core infused with latex for breathability and firm support. Naturalmat uses local organic wool as a natural flame barrier and encases the mattress with two cotton covers, one of which is removable and machine washable.

Hypoallergenic cover treatment?

The mattress cover has an OEKO-TEX® certified hypoallergenic treatment said to protect against bed bugs, dust mites, mosquitos and moths. It’s not clear what this treatment is though and without GOTS or MadeSafe certification for the whole mattress, I’m a bit wary of any claims over toxicity.

Naturalmat says its crib mattress is completely chemical free and made with 100% natural materials from sustainable, Fair Trade sources. Again, these claims are not third-party verified.

The mattress fits standard size cribs and is six inches deep.

Naturalmat shipping and warranty

Naturalmat’s crib mattress comes with a 5-year warranty. For reference, Avocado’s mattress has a 25-year warranty.

The company ships its mattress directly from the UK, so your mattress should arrive within two weeks. Mattresses are not made to order and may be fumigated upon arrival to the U.S. This could involve spraying with pesticides and other undesirable chemicals.

Naturalmat vs. My Green Mattress, Naturepedic, and Avocado

Naturalmat’s Quilted Coco Mat Crib Mattress is quite a bit more expensive than My Green Mattress’s Emily Crib Mattress which is arguably far better in terms of construction and eco-friendliness. 

Naturalmat mattresses don’t seem to have any clear certifications. There’s no link to a valid organic Soil Association certificate for their coconut coir, nor any details of the OEKO-TEX certification for the hypoallergenic treatment for the mattress cover.

In contrast, Naturepedic, Avocado, My Green Mattress, and our other top choices for crib mattresses all carry a wealth of certifications as non-toxic and eco-friendly. Most of these are also more affordable.

Final thoughts on Naturalmat Crib Mattresses

Naturalmat is not transparent about its materials and processes and doesn’t carry GOTS, Greenguard Gold, or MadeSafe certification. The company appears to only use conventional cotton, not organic cotton, and there’s a strong possibility that because these mattresses are imported to the U.S., they’re subjected to fumigation with hazardous chemicals.

Overall, I’m not entirely convinced these mattresses are non-toxic and eco-friendly, though the new (as of 2023) B Corp status helps allay some of those concerns over transparency. Given the price, carbon emissions associated with transportation across the Atlantic, and availability of more eco-friendly, certified non-toxic mattresses made in the U.S., I’d suggest avoiding Naturalmat unless you happen to be in the UK and are in need of a mattress in a pinch.

Naturepedic’s Organic Cotton Classic crib mattress is half the cost of the Naturalmat mattress and is a much better choice all round. Similarly, the My Green Mattress Emily, or Avocado Organic Crib Mattress cost less and are certified organic and MadeSafe.


Does Naturalmat have a crib mattress warranty?

Naturalmat offers a 5-year warranty but no trial period. Instead, all returns have to be handled within 14 days directly with the company. 

Is the Naturalmat crib mattress waterproof?

No. The Coco Mat only has a cotton cover, without any waterproofing. However, Naturalmat does sell a waterproof crib mattress cover made with a polyurethane layer between two layers of organic cotton. Avocado also sells an excellent waterproof crib mattress cover (view on Avocado) as well as a moisture-resistant crib mattress cover made just with organic cotton layers for absorption (view on Avocado).
