Yes, Talalay latex is natural—it is made from natural latex extracted from rubber trees and is processed using biodegradable ingredients. It’s also hypoallergenic and great for the environment because the process uses carbon dioxide, meaning it’s reducing the number of greenhouse gases in the atmosphere. However, unlike Dunlop, it is not 100% natural because it contains polyurethane fillers. This is only really a deal breaker for sleepers who want a completely natural bed, as Talalay is still completely safe. Synthetic latex, on the other hand, is not a safe mattress material and we do not recommend it. Talalay latex is also rarely certified as “organic” because it often has polyurethane fillers. Therefore, if you are looking for a completely organic latex bed, we suggest selecting one made with Dunlop latex. Organic certifications, such as GOLS (Global Organic Latex Standard), guarantee the mattress is made with 95 percent organic materials. There are currently several mattress brands that sell certified organic latex beds.
