Hey Navneet, we are sorry to hear about your experience. All new foam products can have a new smell when they are first opened, especially as they expand. This smell is completely harmless and should dissipate very quickly. A great way to air out this topper is to place it in a well-ventilated room with a fan blowing on it. If there is anything we can do to help, please let us know at info@lucidmattress.com.
Thank you!
