It is perfectly normal for a new mattress/bedframe to have a “new upholstery smell”. In fact, almost all new items will come with a new product smell. Mattresses are made of materials such as foams, latex, memory foam, fabric, etc. While most people are able to accept the smell, some people might not able to accept it. However, the remedy is simple. Increase air flow in the room by ventilating through open doors and windows consistently for a couple of weeks. The smell should go off by then.
