The short answer: A sofa under 70 inches (178 cm) wide doesn't have to be a single chair or an uncomfortable bench. Cozey offers several confirmed two-seat configurations below that limit: Cassini armless at 53 inches (135 cm), Atmosphere armless at 59 inches (150 cm), Neptune with arms at 64.6 inches (164 cm) and Gaia with arms at 67.7 inches (172 cm). They all solve a similar width problem, but they feel and function very differently.
If you're furnishing a studio apartment, narrow living room, home office or secondary seating area, every few inches can matter. The trick is to choose the most useful sitting experience within the actual maximum width—not simply the smallest sofa on the list.

Four genuinely compact two-seat options
Four genuinely compact two-seat options
| Cozey configuration | Overall width | Key benefit | Trade-off |
|---|---|---|---|
| Cassini, armless two-seater | 53 in / 135 cm | Minimum width and curved styling | No armrests |
| Atmosphere, armless two-seater | 59 in / 150 cm | Medium-firm seating, highly configurable | Armless lounging isn't for everyone |
| Neptune, two-seater with arms | 64.6 in / 164 cm | Firm support, tall back, seat storage | More upright feel; larger opened footprint if used as a bed |
| Gaia, two-seater with arms | 67.7 in / 172 cm | Plush, fibre-filled comfort and back support | Loose cushions need regular fluffing |
These are assembled sofa widths for the listed arm configurations. An armless two-seater isn't equivalent to the same two-seater with arms.
Narrowest confirmed two-seater: Cassini at 53 inches
Cassini's armless two-seater is only 53 inches (135 cm) wide and about 36 inches (91 cm) deep. That's a useful footprint for a small room with a doorway beside the sofa or for someone who wants to keep space for a desk or bookshelf.
Cassini has a softly curved silhouette and medium-firm, layered-foam seating that slopes gently toward the back. That gives a subtly cradled position without the loose fibre-filled cushion care of Cozey's cloud-style collections. Its upholstery covers are removable and machine-washable.
The trade-off is clear: no armrests. If you like to lean against a side arm or rest your head on one, this minimal layout may not provide the experience you want. The arm-equipped Cassini two-seater is about 72 inches (183 cm) wide, placing it just above the under-70-inch category.
Best for a compact, supportive armless sofa: Atmosphere at 59 inches
Atmosphere's armless two-seater measures approximately 59 inches (150 cm) wide. Its medium-firm layered-foam cushions have a more structured feel than Ciello or Gaia, and its modular design supports different backs and arm choices if your room changes later.
Atmosphere can also offer regular, storage or sleeper seating in compatible configurations. That's valuable if you want more than one function from a small piece of furniture, although adding a sleeper arrangement or ottoman changes the total space needed. Its upholstery can be removed and washed across upholstered components, and compatible covers can be replaced.
For a room where you want no arms and don't like regularly fluffing loose cushions, Atmosphere deserves consideration alongside the smaller Cassini.
Best under 70 inches with arms and storage: Neptune at 64.6 inches
Neptune's 64.6-inch (164 cm) two-seater is a useful answer to the question, Can I keep proper armrests and still stay under 70 inches? You can. Neptune also provides a tall backrest, supportive firm seating and storage inside each sofa seat.
This is especially practical in a multipurpose room where blankets and guest bedding need somewhere to go. Neptune's sofa-bed system can offer guest sleeping, but be precise: the referenced full-size arrangement requires the two-seater plus compatible storage ottomans. The sofa-only width isn't the total sleeping footprint.
Seat and back cushion covers are removable and washable. Arm and base upholstery is fixed, so Neptune doesn't offer the same full-cover colour-changing flexibility as Cassini or Atmosphere.
Best under 70 inches for soft, plush comfort: Gaia at 67.7 inches
Gaia's 67.7-inch (172 cm) two-seater with arms is the plush choice in this group. It combines supportive high-density foam with soft synthetic-fibre cushions, a taller backrest and French-seam styling. It offers the relaxed, cloud-like sit many people want without needing an 80-inch-wide sofa.
Because the cushions are loose and soft, they need to be fluffed regularly and rotated to preserve their shape. The upholstery covers are removable and machine-washable, and compatible replacement covers can refresh the sofa over time.
Gaia is especially worth considering when a 70-inch width cap is strict and you don't want to give up armrests or a soft lounging feel.
How much clearance do you actually have?
Before choosing the widest sofa that fits on paper, measure the clear space between trims, mouldings or obstacles. Consider where the sofa's arms finish, not just where the cushions start. If the wall is exactly 70 inches long, a 67.7-inch Gaia leaves around 2.3 inches total before any installation allowance, while a 64.6-inch Neptune leaves more room.
Then check depth. A narrow sofa might still project farther into the room than you expect. Finally, think about future needs: if you move to a larger space, some modular configurations can be expanded with compatible modules instead of replacing the original sofa.
Which small two-seater should you choose?
Choose Cassini for the narrowest confirmed footprint and a sculptural, medium-firm feel. Choose Atmosphere for a compact armless sofa with structured cushioning and extensive modular options. Choose Neptune for supportive arm-equipped seating and hidden storage. Choose Gaia if you want proper arms and the softest, most cloud-like experience among these four choices.
