If you're a renter or someone who's just a little afraid of committing to a big furniture piece, opting for a modular sofa over a traditional sofa is a smart move. Modular furniture is composed of individual pieces that connect together, which makes it incredibly easy to take apart and rearrange. Not only does that make moving easier, but it also gives you tons of options for customizing the perfect configuration for your life (and you can add or remove pieces as necessary).
