Inspiration photos. Different tables will make it more interesting, furniture that looks changed over time is a good look.

My home is a mishmash of yard sales, consignment stores and family pieces, as in first two photos (chair is a work in progress). Nothing matches. However I do try to keep a common thread in every room... Maybe wood color or painted furniture. If you decorate this way, you need to build the room slowly as you come across pieces that you like. Otherwise go to ikea and see what they have. They tend to have eclectic stuff.

No..they don't have to match!

I have a blog post that may help you with your project

Too much matching makes for a boring space .
