Summary: If you have old furniture in your house that you no longer want to use, do not be so quick to throw it away. There are other options you can explore to make the furniture useful again.
Whether what you have back at home has gone through normal wear and tear or you simply want to buy that new piece you saw at the mall, you might find yourself in a position where you want to get rid of some furniture. If the furniture you want to get rid of is in bad enough shape that it should not be used at all, then the only practical option is to throw it away. However, if the furniture in question is actually in fairly good condition, you have various options for how you can proceed with it.
If the furniture you no longer want is in good condition and you want to get rid of it quickly, you could look into donating it. There are shelters and online groups you could reach out to that might be willing to take the furniture from you. There might be someone in your neighborhood or there could be a homeless shelter that could make good use of the couch cushion you want to replace for the memory foam one you found at The Foam Factory. Certain items, such as bed mattresses, could be very dirty and difficult to clean. Most non-profit organizations will not take these items.
Alternatively, if you want to make some of the money you spent on the furniture back, you could find online markets where you can sell used furniture to people nearby.
Depending on what you want to get rid of, you might be able to repurpose the furniture. That patio cushion that no longer matches the theme you are going for could easily be turned into an outside bed for your dog. Thinking creatively to find new ways to use old items can save you money.
