The answer to 'why is my upholstery odor' is that there are several common causes, including spills, pet accidents, smoke, and mold or mildew. Upholstery can absorb odors over time, and if not properly cleaned and maintained, these odors can linger and become increasingly noticeable.
Some common symptoms of an upholstery odor problem include a musty, stale, or unpleasant smell, especially when the furniture is moved or sat on. The odor may also be more pronounced in humid or warm environments. Identifying and addressing the root cause is crucial to resolving the issue.
