Loom & Leaf memory foam is 100% hypoallergenic and non-toxic and will never off-gas or smell in your home. We use eco-friendly foams that are certified to be low-VOC and free of harmful chemicals, an organic cotton cover, and natural thistle flame retardant. Our cooling Spinal Zone Gel is made from non-toxic, water-based materials that contain no chemicals or irritants. As a final step, we treat the cotton cover with Guardin, an antimicrobial that inhibits bacteria and extends the life of the material.
