To begin, pick a coffee table that fits in your space, whether that be round, square or rectangular, and choose something that pairs well with your other furniture, especially your couch. Next, use a few of your favourite coffee table books to ground the table, and set a base for the beautiful objects on top! Before going on the hunt for new books, shop your own home - I'm sure you have some good coffee table books lying around somewhere (and yes, they're called coffee table books for a reason)!
Again, depending on the size of the table, either on top or next to the coffee table books, I usually look for either a tray, basket or marble slab to act as a "command" centre for all the knick-knacks I put on top.
Now that you have your base, it's time for the fun part! A short vase with your favourite flowers or greenery (my love of eucalyptus is so real) is a staple for a well-styled coffee table. I don't always include flowers, but if you're having a get together with friends, or simply feel like treating yourself, a coffee table is a great place to put those bad boys on display.
