Everything You Need to Know About Modular Sofas
Lately, it seems like modular sofas are everywhere—but what exactly are they? And why are they becoming the go-to choice for so many people? Whether you're furnishing a new space, upgrading your living room, or just sofa-curious, we’re here to break it all down.
From what a modular sofa is to its benefits, different types, and how to choose the right one for your space, this guide has everything you need to know. So, let’s dive in.
What Is a Modular Sofa?
A modular sofa is made up of multiple sections, or modules, that can be arranged in different configurations. Unlike traditional sofas that come in fixed shapes, modulars offer flexibility—you can either buy them as a pre-set configuration or build your own by selecting individual pieces.
Why does this matter? Because whether you have a spacious open-concept living area or a cozy apartment, a modular sofa allows you to customize your seating to fit perfectly. Plus, they’re great for rearranging—whether you’re hosting guests, moving to a new space, or just in the mood for a refresh.
Why Choose a Modular Sofa?
Modular sofas are a game-changer for a few reasons:
They’re versatile. Modular sofas allow you to create different shapes to suit your space—whether that’s an L-shape, U-shape, or even a simple straight-line setup. They fit easily into tricky layouts or awkward corners, making them perfect for maximizing space. Plus, you can expand or reduce the size over time by adding or removing modules as your needs change.
They’re adaptable. You can rearrange some modular sofas, whether it’s for a movie night, a party, or just because you want a fresh look. You can also use different modules in various rooms as your needs evolve, which is especially useful if you’re in an apartment but plan to move. Need to make room for a holiday tree or an at-home yoga session? Simply shift your setup to create more open space.
They save space. With a modular sofa, you can design a setup that only takes up the space you need, helping to keep your floor plan open while still providing plenty of seating. Plus, different modular pieces can serve multiple purposes. Case-in-point: pop a tray on your ottoman to use it as a coffee table.
Types of Modular Sofas
Modular sofas generally fall into two main categories, each offering a different level of customization and flexibility.
Three-Component Modular Sofas
These are made up of just three main pieces: an armless chair, a corner chair, and an ottoman. The armless chair can be placed anywhere, the corner chair serves as the perfect end piece, and the ottoman can be used as a footrest, extra seat, or coffee table. With this setup, you can create anything from a compact two-piece sofa to a sprawling U-shaped sectional. A four-piece configuration might include two corners, one armless chair, and one ottoman. Our Movie Night™ and Get Together™ collections embody this concept perfectly, featuring ottomans that can be moved around easily. This means you can create a left- or right-hand chaise, position the ottoman in the center as a table with a tray, or even arrange it into a cozy “pit” setup—ideal for lounging or hosting the ultimate movie night.
Left- or Right-Facing Modulars
These sofas are designed with a fixed orientation, meaning the modules aren’t interchangeable. Instead, you choose left- or right-facing components based on how you want the sofa to fit in your space. (Pro tip: left or right describes the orientation when you’re standing and looking at the sofa.) The arms and backs are designed specifically for one side, so a left-arm chair has a different design than a right-arm chair. These sofas typically come in two or more pieces, offering a structured, polished look. While they may be less flexible than three-component modulars, they allow for a more tailored aesthetic that fits seamlessly into your space. Our Wind Down collection has five components (a left-arm chair, right-arm chair, corner chair, armless chair and ottoman), while our Come Around pairs a two-seat bench with either a left- or right-facing chaise.
Modular vs. Sectional: What’s the Difference?
Surprise! Modular and sectional are used interchangeably. Traditionally, “sectional” refers to sofas with an L- or U-shape, while “modular” simply means the pieces can be rearranged. Comparatively, a “sofa” is generally a single, fixed piece (sometimes also called a “bench sofa”).At Sundays, our modular sofas come in all shapes and sizes, including sectional and straight-line options.
Choosing the Right Modular Sofa for Your Space
There’s no one-size-fits-all when it comes to modular sofas. Here’s how to find the right one for you:
Assess Your Space and Needs Measure your space to determine what size and shape would work best. Consider how many people you need to seat regularly and whether you want the option to rearrange it often.
Consider Your Design Preferences Modular sofas generally have a contemporary aesthetic. If you prefer a cleaner look, a left- or right-facing modular might be a better fit. If you love the freedom to rearrange, a three-component modular is the way to go.
Different modular pieces can serve multiple purposes. Case-in-point: pop a tray on your ottoman to use it as a coffee table.
