Taking with you furniture from an old house to your new place is like trying to fit into clothes from years ago. While you may still very much like these pieces they may not fit and blend in as they once did a while ago. There are ways to adapt old favorites and make then good as new again if you are willing to get a bit creative.
Change things up
Things in a room do not have to follow a specific order and layout, especially when it comes to the living and dining room areas. Once you figure out which piece goes where, you will then be able to know which parts of the furniture to do without and which to keep.
Here is your chance to reuse those staple pieces you are not quite ready to get rid of. You could change the legs of that coffee table you love so much or use the small dining table as a work space for your home office. You could reuse an old sofa or matress by putting it in the den or family room. Throw on a few pillows on it and you are good to go.
The only true way to know if a piece fits in a room or not is to try putting it in different rooms to see if it works well or if it needs a new home. Do not worry about creating symmetry as long as the pieces tie in with the entire look of the room.
There really is no need to throw out the old pieces that you once loved, there is a myriad of way you can repurpose pieces. You could always consider giving them way or selling them and let someone else enjoy them.
