GREENGUARD Gold certified and assembled in Arizona, the premium Birch natural mattress by Helix is expertly designed for a medium-firm feel that's perfect for side sleepers, as well as back and stomach sleepers. Made with a breathable organic cotton cover as the top layer, hygroscopic organic wool and 100% organic, GOLS-certified latex layers increase airflow and keep you cool for a good night's sleep.
