13 Stylish Modular Sofas We Love for Living Rooms Both Big and Small

Interior Define is the place to go for anyone who likes their sofas to meet their exact standards—no matter how specific those standards may be. This retailer lets you customize pretty much every detail of the pieces, including this modular sofa. Choose between 400 fabrics (free swatches included), two sizes, and two cushion fills. They're both cozy, but if you want that sink-in feel, go with the down. The best part about ordering a sofa from Interior Define is the ability to see the proportions with an actual person for scale. At the bottom of the product page, you can see two videos featuring people of different heights walking around and sitting on the sofas. Trust us; there will be no buyer's remorse here.

Generally speaking, couches—especially large couches—are expensive. So when we found this 106-inch-wide find for $500, we had to add it to the list. It doesn't hurt that it comes with plenty of positive customer feedback. One person said, "This sofa is so amazing and so comfortable it’s crazy, and it’s super easy to put up." It's also available in seven neutral shades, including this cool-toned charcoal shade.

If this leather-clad sofa looks a little too big for your space, feel free to opt for the two-piece version, which is only 72 inches wide. Otherwise, enjoy this 108-inch one that's as plush as it is supple, and it's contract-grade, so there's no need to moisturize the leather; it will hold up just fine on its own. Plus, you can get it in genuine or vegan leather.

We love a sofa that can grow with you, like this option from Sundays: it can be configured as two pieces or, when you're ready and have more space, add on to the sofa and turn it into six pieces. "Every time we have guests over, they rave about how comfy this couch is—even friends who have slept on it overnight," tester Samantha Jones says. "The deep seats and pillowy cushions make it easy to curl up on while providing adequate support. Plus, even though I was very skeptical about the longevity of a white couch (especially in New York City), I have found the upholstery quite easy to clean with a vacuum or my Bissell Little Green machine." This one is only two pieces, making it that much easier to move and clean.

Do you want a sofa you can comfortably fall asleep on? Check out this pick. When Associate Commerce Editor Jessica Cherner moved out of her 350-square-foot New York City apartment into her current 800-square-foot one, she had one big non-negotiable: she needed a big couch that she and her fiancé could spread out on.

However, when she started her shopping research, she hadn't signed the lease yet, so she didn't know the configuration that would work in her future space. So rather than buy a left- or right-facing sectional and hoping it would work, she opted for a modular sofa with a movable chaise.

This Crate & Barrel one is available in a whopping 252 fabrics and two-leg finishes, so you can get precisely what you're looking for, no matter how specific your vision may be. It's filled with fiber, not down, so it won't have that sink-in feel, but it's the perfect balance between plush and supportive. Plus, because there are no feathers, there's no fluffing required. “I can't tell you how many times I've fallen asleep on the chaise,” Cherner says. “It's just so comfy, and the seat is deep, so you're forced to sit in a lounge-like way versus straight up with a 90-degree angle between your lap and torso.”

Leather sofas–as long as you keep them out of direct sunlight—are low maintenance, especially the ones from Burrow. "I've had my Nomad sectional for six years, and aside from having to vacuum out dog hair and granola crumbs (I blame my husband) underneath the cushions occasionally, it needs minimal cleaning. When I spill on it, I wipe it down with a lightly damp towel, and it's good as new," Senior Commerce Editor Marina Liao says. "I have allergies to dust and dander that get trapped in fabric sofas, so I knew I wanted a leather sofa and one that was modular, too. The chaise here is removable, making it easy to have it on the left or the right. In my old apartment, the chaise was on the left side, and now, in my new home, it's on the right, so the chaise doesn't completely block my fireplace. You can also add on to this sofa by inserting more pieces, but because of my living room space, I'll have to just stick with three seats for now." Don't love leather? You can also get this sofa in other fabric options, including velvet.

You've probably heard a lot about cloud couches, and before you ask if it's worth buying, the short answer is yes. "I used RH's design service to decorate my New York City apartment and gave my assigned designer free rein to choose products as she saw fit," tester Benjamin Cherner says of his Cloud Couch. "The only guidance I gave her was incorporating darker pieces and making everything as comfortable as possible, which is how I ended up with this striped area rug and my Cloud couch. It's modular and can be arranged to fit a specific space, but I preferred this L-shape sectional. The seat is really deep (48 inches), so it's a great place to relax. Plus, my new puppy Roy loves it," he adds.

We can't speak for Roy, but we can guess it's a popular place to sit because the seat and back cushions are filled with 100 percent down feathers. If you're familiar with down-filled sofas, you know they require more maintenance than down- and fiber-filled ones because there's little support to keep the cushions from slumping once you stand up. "I don't fluff mine a lot, so it does have clear divots from where I sat, but that doesn't bother me," Cherner adds. "The down makes it extremely soft and comfortable to sit on."

The husband-and-wife duo behind Albany Park have launched many a sofa, but the most famous is easily the only modular one on offer: the Kova. As you may be able to glean from the images, the sofa is completely customizable in terms of configuration by rearranging the various pieces, including the ottoman, which can be used to create a U-shape sectional. Did we mention that there are many fabric options depending on what you prioritize? Opt for kid- or pet-friendly options, or go with stain-resistant alternatives. If you want all three, you have plenty to choose from. The best part is the ottoman, which you can get with or without storage.

"I love the sofa so much. I got the loveseat, and it's comfortable and cozy, and it gives me that sitting-on-a-cloud experience without hurting my back," Liao, who tested this sofa, says in her review. "My husband, who is more of a napper than I am, has slept on this comfortably and said it was a good 'napping couch.' Both the back and arm cushions are very plump and spongy, which makes for a soft giant 'pillow,' and the seat cushions give in, so you feel like you're getting the most optimal loungey experience. According to Albany Park, the cushions are filled with a 'cloud-soft, hypoallergenic microfiber blend.' I also feel like the performance linen doesn't trap heat, so even though my house gets humid come summer, I feel cool sitting or sleeping on the Kova."

Pro tip: Make sure to measure your space correctly, as the couch does feel big in smaller spaces.

The ottoman alone could double as a bed because it's so big! It's 44.5 square inches, so scoring a spot on the sofa with ottoman access is the best seat. The rest of the couch is vast enough to spread out and relax. One reviewer wrote, "Comfortable to sit on but not to sleep on," which is worth knowing but not necessarily a dealbreaker since sofas are not beds. If you like this sofa, get it fast because there are only a few left in each color.

Cozey’s Neptune line is one of its most popular due to all the various arrangement styles, performance fabric options, and washable covers. Tester Andrew Jarrett opted for an L-shaped configuration in green and says the delivery was seamless because the pieces arrived in multiple boxes that easily fit through the door. “We can fit about eight people on this couch, and my friends were saying how comfortable it is,” he notes. “We got storage with the couch, which is a good place to put our extra blankets and pillows. My daughter is able to climb and play on this and the couch has been sturdy and looks as good as new even half a year later.”

Before buying this sofa because it's seemingly only $899, know that that's the price for one piece (the corner chair). Why, you may ask, does Article not sell the sofa as a whole? It's modular! It's meant to be purchased à la carte to create your custom sofa using modular pieces. It comes in 12 colors (nine fabric and three velvet), so feel free to pair your new modular sofa with the pre-existing palette in your space.
