Yes, pillow foams infused with cooling gel are safe and non-toxic. While some gel memory foam pillows may have a slight order at first, this should dissipate after 2 to 3 days. If you are sensitive to smells or have allergies, look for gel memory foam pillows with a CertiPUR-US certification. This third party certification guarantees the pillow is free of harmful additives and has minimal VOC off-gassing (the “new” pillow smell).
