It is not uncommon for a new Purple mattress to have a slight odor when first unwrapped. This scent usually originates from the materials used in the construction of the mattress, specifically the hyper-elastic polymer and some of the foam layers. Typically, this odor is not harmful and should dissipate over time as the mattress airs out.
To help minimize the odor, it is advisable to first remove all packaging materials and allow the mattress to breathe in a well-ventilated area. If possible, placing the mattress near a window or outside on a dry day can promote faster air circulation. Most odors should fade within a few days to a couple of weeks, depending on the environment.
If the odor persists beyond this period or becomes bothersome, it may be worthwhile to consider how the mattress is being maintained, including the foundation being used. For the most current information on care and maintenance, it would be beneficial to explore the relevant sections of the Purple website for guidance.
