7 Best Sustainable Mattress Toppers

Want to go green with your bedding? These sustainable mattress toppers are filled with natural or eco-friendly materials. They skip the chemical foam in favor of things like wool, cotton, bamboo, or even coconut fibers, so you can sleep soundly and guilt-free.

Coconut Coir Mattress Topper

:contentReference[oaicite:4]{index=4}This Japanese-style coconut coir topper is interesting and eco-friendly. It's made of layered coconut fibers covered in fabric. The 5cm thick coconut coir mattress topper is firm, perfect for airflow, and naturally resistant to dust mites. It’s a traditional tatami-like topper, not plush, but provides firm support with a natural twist — great for an eco-conscious bed boost.

Wool Mattress Topper

For a soft, temperature-regulating layer, check out this wool topper. Filled with 100% natural British wool and wrapped in cotton, it wicks moisture and feels cozy. The Slumberdown wool mattress topper is fluffy and light, yet it helps keep you warm in winter and cool in summer. Natural wool is sustainable and biodegradable, so you get warmth with a clear conscience.

100% Cotton Mattress Topper

This cotton topper is pure fiber through and through. It uses 100% cotton filling and cover for breathability. The UK Care cotton mattress topper is 10cm thick with a quilted design, giving you plush comfort with no synthetic fill. Cotton is renewable and recyclable, making this a green choice. It’s snug like a feather topper but fully plant-based.

Organic Cotton Mattress Protector

Add this organic cotton mattress protector for extra sustainability. Made of 100% cotton and GOTS-certified, it adds a soft layer on top of your mattress. The Whisper Organics cotton protector is lightweight and highly breathable. It won’t noticeably change mattress feel, but it keeps your bed hygienic and feels nice, all while avoiding harsh chemicals.

Natural Latex Mattress Topper

Finally, consider natural latex. Made from rubber tree sap, it’s a durable and sustainable foam alternative. The Talatex natural latex mattress topper is medium-firm and topped with organic cotton. Latex is biodegradable and long-lasting, so this topper can protect your bed without introducing synthetic stuff. It bounces back instantly for support while being kind to the planet.
