We're living in a heyday of mattresses, with hundreds of brands vying for our attention both in stores and online. In addition to claims of comfort and support, many mattresses are now marketed as 'non-toxic'—but what does that really mean, and is it important?

We spoke with Charlotte Vallaeys, a Consumer Reports senior policy analyst, and Tasha Stoiber, Ph.D., a senior scientist at the Environmental Working Group, to break down exactly what you need to know about low-toxicity mattresses. These two experts spend their days researching how the materials in our homes impact our health.

Here's their top insight on which mattress materials to look for (and avoid), which labels you can trust, and which brands are doing it right.

Nontoxic mattress materials.

Avoid: Polyurethane foam

Stoiber, an EWG senior scientist and co-author of the group's Healthy Living Home Guide, cautions against mattresses made from polyurethane foam for health and environmental reasons.

"The majority of mattresses on the market are made from polyurethane foam based on petroleum chemicals, so it can off-gas volatile organic compounds, which can cause respiratory irritation, skin irritation, etc.," she tells mbg.

Though more research still needs to be done, one study found that babies are particularly susceptible to these chemicals, and their cribs may be the source of up to 30 volatile organic compounds (VOCs) that range the gamut from phenols (often used as antiseptics) to formaldehyde (a potential carcinogen found in glues and adhesives).

Even if you don't have a child, it's probably best to avoid these chemicals where you can, especially with something you use as often as a mattress.

Look for: 100% natural latex foam

Instead of synthetic polyurethane, look for mattresses made from natural materials like latex, wool, and cotton. The EWG's top choice is 100% natural latex foam, which is extracted from rubber trees and isn't treated with as many chemicals as polyurethane during manufacturing.

These days, the rise of direct-to-consumer models have made natural latex (a historically pricey option) slightly more affordable, but you need to ask a few questions to ensure you're getting the most bang for your buck.

"You have to be careful because some brands might say it's a latex mattress, but really it is made from synthetic latex. Or, only the top inch is latex and it has polyurethane underneath, so you need to find out the composition of the mattress and know what each layer is made of," Stoiber cautions.

The best nontoxic mattress labels.

After researching 12 mattress labels to verify or dispel their health and sustainability claims, Vallaeys and Consumer Reports found mixed results: "There's a lot of variability when it comes to what the labels address," she explains.

"Some of them address just one thing while others will address everything from the farms that grow the mattress materials to the factories where the mattress is made to the likelihood that a mattress will off-gas once you start using it."

Some of the more comprehensive, holistic labels are Oeko-Tex Standard 100 and Greenguard Gold, which set strict limits on VOCs, flame retardants, and dyes.

The winners, though, are the GOTS and GOLS labels, which signify 95-plus% certified organic textiles and latex, respectively. Mattresses with these labels also have a substantial list of banned substances and were made in a way that champions the environment.

"GOTS and GOLS were very comprehensive, all the way from the farm to the final product," Vallaeys says, and Stoiber echoed that the labels holds the most weight.

Other things to look for in a safe mattress.

While mattress layer materials are important to pay attention to, you'll also want to look into what's holding your mattress together: Opt for water-based glues over synthetic solvent-based ones, which can pollute the air.

Finally, make sure that your mattress has absolutely zero chemical flame retardants. A handful of states are now in the process of banning flame retardants, but until this is the norm, keep an eye out for this unsafe (and ineffective) additive.

The bottom line.

Mattresses made from natural latex foam tend to be the best nontoxic option (bonus points if they are GOLS certified). While mattresses made from this material tend to be a bit pricier, they are worthy of the investment. Top them with some breathable, natural sheets, and consider your sleep sanctuary set.
