Hi Adam, this is Brookside.
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. This topper is CertiPUR-US certified for quality and safety and is safe to use.
We're sorry to hear you aren't happy with that topper! Comfort preferences vary and we understand if it wasn't the best fit for you. We hope you are able to find something that works better for you.
