Looking for the ultimate cozy sofa without spending hours researching or testing in-store? You’re in the right place. We’ve done the work for you—sorting through top brands to identify what actually makes a sofa truly comfortable. We’ve identified a few key factors to keep in mind. Deep seat dimensions and plush, supportive cushions are essential for a lounge-worthy experience. Just as important is the cushion composition: many sofas use a single-density foam core, which can flatten over time and lack support. The best designs layer multiple foam densities to balance structure and softness—offering a more durable, sink-in feel that lasts. Read on for our picks of the most comfortable sofas and what sets them apart.

The Big Picture
The Modular Performance Sofa by Anabei - Customer’s Choice
Anabei revolutionizes modern furniture expectations, delivering a perfect fusion of durability, comfort, sustainability, and affordability tailored for contemporary family living. Its pet-friendly, stain, and liquid-resistant fabrics make it the practical choice for households with furry friends or young children. Cleaning is a breeze with the entire sofa being machine washable, including the dacron duvet layer and fabric covers. Anabei's plush slipcover frame and cushion design is crafted to provide unparalleled coziness without the need for constant fluffing (typically a pain point with this style of sofa).
Boasting a sturdy steel frame, Anabei guarantees enduring quality. The ability to swap covers and a modular design empower you to adapt to your evolving lifestyle and preferences. Sustainability remains at the core of Anabei's ethos, evident through their eco-friendly practices: a commitment to no PFCS, upcycling plastic bottles, carbon-neutral shipments, and the use of CertiPUR foam. Their no-risk satisfaction guarantee provides you with 30 days to decide if it's a perfect fit, promising a full refund if you're not satisfied. Anabei stands as a testament to quality and affordability, offering a sophisticated look without breaking the bank.
Compared to Sixpenny: Both offer a similar style, but Sixpenny comes with a price tag more than triple that of Anabei. While Sixpenny offers two insert options and a broader range of fabric types, it's essential to note that not all of their fabrics are performance grade, and none are machine washable. Additionally, Sixpenny offers a 30-day return policy, but with restocking fees, unlike Anabei, where returns are 100% free—an almost unheard-of benefit in the e-commerce furniture space.
Verdict: Anabei offers an incredibly affordable sofa (they start at $639) that's a game-changer - it's the first 100% machine washable sofa. It checks all the boxes for modern life being high performance, and transformable in nature with its modular design and changeable slipcovers. It’s great for homes with pets, kids, and is an overall high resilience, low maintenance choice with its machine washable layers and plush cushion design that requires no fluffing. And it’s risk-free—you can return it for 100% of your money back if you’re not in love.
The Modular Harmony Collection by West Elm - Best Seller
The Harmony Collection is West Elm’s number one recommendation for comfort in their sofa category. They say that on a scale from 1-5 (5 being the most firm), the Harmony is a 1. Its low profile design is perfect for a luxurious lounge and it features pillow-soft cushions. The extra lumbar and arm pillows are included with the sofa and allow you to find a comfortable seat in any position on the sofa. They took extra care in designing the cushion composition as well. The back cushions are 50% polyester fiber, 45% duck feather and 5% duck down. This combination is very soft but also needs regular fluffing, so they created reversible back cushions that can be occasionally fluffed and then reversed to help them maintain their shape. The seat cushions are high-density polyurethane foam. In addition to being comfortable, the seats are also spacious with a 34 inch depth and 43 inch width. If you’re looking for a soft upholstery we recommend choosing one of their velvet or boucle options. You can order free swatches to feel them out in person before picking the right one for you. And finally, the modularity of this sofa allows you to also choose the perfect configuration to meet your comfort needs. For example, if you like to kick up your feet on either end of the sofa simply add a chaise on either end.
Verdict: The Harmony is West Elm’s self-proclaimed softest and most comfortable sofa. Its spacious seats and down feather cushions will make you melt. The modularity of this sofa will allow you to choose the perfect confirmation for you.
The Washable Cloud Sofa by Diorama Living – Designer’s Favorite
What makes the Diorama Cloud Sofa a standout favorite among designers and customers alike is its perfect balance of elevated design and everyday practicality. Each piece is wrapped in high-performance fabrics that are not only liquid- and stain-resistant, but also offer pet-friendly, snag-resistant options—ideal for busy households. The entire sofa is 100% machine washable, including the plush duvet and tailored slipcovers, offering unparalleled ease of cleaning. Thanks to its resilient construction—including cushions and pillows engineered to retain their shape—it delivers a sink-in feel without the need for constant fluffing. Beneath the softness lies a powder-coated steel frame, engineered for long-term durability and support.
But the Diorama Cloud Sofa isn’t just thoughtfully designed—it’s also made with sustainability and flexibility in mind. All foam used is CertiPUR-US® certified, ensuring low emissions and zero harmful chemicals, and the fabrics are entirely free of PFAs and PFCs. Modular and customizable, the Diorama Cloud adapts effortlessly to evolving spaces and tastes, with interchangeable slipcovers that allow for seasonal updates or design refreshes. And with a no-hassle, 30-day return policy—free of shipping or restocking fees—you can experience the comfort of the Diorama Cloud risk-free, knowing it’s as easy to live with as it is to love.
Compared to 7th Avenue: Both Diorama and 7th Avenue offer stylish sofas that appeal to modern, design-conscious shoppers. While 7th Avenue includes some modular features and removable covers, Diorama stands out with its fully machine-washable construction and truly interchangeable slipcovers—providing greater flexibility and ease of care. Diorama also offers more accessible pricing and a risk-free 30-day return policy with no shipping or restocking fees. By contrast, 7th Avenue markets free returns but in reality, charges return shipping and limits returns to 10 days. While 7th Avenue is still a quality option, Diorama delivers a more flexible, washable, and comfort-forward experience at a more accessible price point for the modern home.
Verdict: The Diorama Cloud Sofa earns its name with an ultra-comfortable, sink-in design that’s made to be enjoyed by all shapes and sizes. Its extra-wide, extra-deep seats create a spacious, lounge-ready feel, while layered cushion densities strike the ideal balance between plushness and support—so you can truly relax without feeling weighed down. Whether you prefer to stretch out solo or sit upright with added lift, optional bolster pillows provide customizable back support for every posture. Combined with its modular flexibility, machine-washable covers, and steel-framed durability, the Diorama Cloud is more than stylish—it’s a comfort-first haven built for real life.
The Modular Bondi Collection by Inside Weather - Editor’s Choice
Inside Weather's the Bondi sofa has proved itself to one of the most comfortable collections on the market and the reviews follow suit. How? Its design features oversized, cloud-like cushions that offer a spacious surface area to “sink in deep, and then deeper.” The back pillows are also extra large, providing an all around cushy feel when leaning back. Choose between their two luxury comfort cushion options. The Classic Plush Blend cushion gives a dense yet cozy seat and is made from layers of medium, and low density foams, both of which are high resilience. This means they maintain their integrity over time. Then to top it off, it’s wrapped in a plush layer of their 100% recycled down alternative. Their Deluxe Memory Foam Cushion option features a high resilience, medium-density foam that’s also wrapped in an alternative down layer. And for extra cloud-like appeal, it features an additional layer of temperature-regulating memory foam. The plush back cushions are also filled with their recycled down alternative. Even the frame is specifically designed for comfort with a tapered back, allowing you to sink in. Its base is designed with a webbing system of elastic straps that contribute to that subtle bounce you will love. Inside Weather also provides a generous amount of upholstery options. To maximize your comfort, we suggest choosing a velvet, suede or boucle fabric.
Compared to LoveSac: Customers often compare these two given their modular designs. LoveSac presents a more traditional sofa style whereas Bondi presents a more unique modern silhouette. Inside Weather has more performance fabrics to choose from and every single part of the fabric is washable whereas LoveSac offers removable portions of fabric. Both offer above average return policies—LoveSac with a 60 day window, and Inside Weather boasts a 365 Home Trial.
Verdict: The Bondi’s deep and spacious cushions with customizable inserts make it one of the most comfortable sofa designs for consumers within this price range out there at the moment. Choose between their Classic Plush Blend or Deluxe Memory Foam cushions, both of which have layers of medium and low density foam and wrapped in their cruelty-free 100% recycled down alternative. The Deluxe Memory Foam cushions take it a step further with an extra layer of memory foam for an extra sink-in feel.
The Modular Bryant Collection by Joybird - Trending
The Bryant Collection is designed for ultimate luxurious lounging. The cushions are made from high-density foam and multi-layered fiber sheeting that will keep you coming back. And don’t be worried when the cushions naturally soften and flatten over time, it won’t take away from the overall comfortable feel of the sofa. Joybird calls this style of sofa, loose back and loose seat. This means that the cushions are meant to be a bit floppy. Every surface of this sofa is covered with an oversized cushion or pillow. So, no matter how you lounge, you will never find yourself bumping into a hard surface. They also designed the frame with comfort in mind. Instead of making it completely out of wood, they made it predominantly from foam. They say the foam frame may lead to more noticeable wear and tear than traditional sofas, but they do offer a lifetime warranty to ease your worries. The seat height is 21 inches which is taller than the average sofa usually ranging from 17-18 inches in height. Also check out the 5 star rave reviews on their website—its cloud-like appeal has people talking!
Verdict: Joybird describes The Bryant as having a “loose back and loose seat design.” Its floppy cushions and predominantly foam frame gives the sofa a luxuriously plush feeling. It’s taller than the average sofa, so it’s just as easy to stand up from the sofa as it is to fall into it.
The Sunday Collection by Blu Dot
It's all in the name for this collection. It’s perfect for that Sunday afternoon snooze, or to curl up with a book for hours. These extra deep cushions are made for melting into. The thick, oversized back, seat and arm cushions are stuffed with high resiliency foam that’s wrapped in feathers and down. Because every surface of this sofa is covered with such thick cushions, it allows you to find a comfortable seat in any position. Even though the Sunday is not modular, they do offer many different configurations. And instead of wood slats under the seat cushions, it has webbing that gives durable support. However, their website does not describe the webbing material. Blu Dot designed the Sunday with a thin frame intentionally so the oversized cushions steal the show. They do recommend fluffing and flipping the reversible cushions to promote even wear over time. Finally, we recommend choosing their beautiful Camel Velvet upholstery fabric for an even softer appeal to your seat.
Verdict: The Sunday design puts the spotlight completely on the cushions. The thin frame emphasizes the size and comfortability of the oversized cushions which are filled with high resilience foam wrapped in feathers and down. Just make sure to regularly flip and fluff the cushions so it wears evenly over time.
