Short answer: Cozey's Atmosphere and Gaia are both modular sofas that sit very differently. Atmosphere is medium-firm and 27.5 inches (70 cm) deep, with Storage and Sleeper versions. Gaia is soft, with loose cushions and a high back. Choose Atmosphere for function, Gaia for softness.
Both are modular and both have removable covers. The choice comes down to how firm you want the seat, how much floor space you have and whether the sofa needs a second job, such as storage or a guest bed.

What is the main difference between Atmosphere and Gaia?
At Cozey, we build Atmosphere for structure and function and Gaia for softness. Atmosphere has D35 high-density foam seat cushions that give medium-firm support and keep their shape without routine fluffing, and it comes in three versions: Regular, Storage and Sleeper. Gaia has thick, loose cushions of polypropylene fibre fill around a D35 foam core, over a seat base with a further 1.5 inches (4 cm) layer of D35 foam, and it comes in two sizes, Regular and XL.
Our guides to Atmosphere and Gaia go through each sofa in full.

Which has the deeper seat, and which feels softer?
Atmosphere has the deeper seat, and Gaia has the softer one. Atmosphere seats are 27.5 inches (70 cm) deep with the square back and 29.5 inches (75 cm) deep with the round back. Gaia is 24.0 inches (61.5 cm) deep in Regular and 25.5 inches (65 cm) in XL, so Atmosphere is about 3.5 inches (8.5 cm) deeper than Gaia Regular and about 2.0 inches (5 cm) deeper than Gaia XL with the square back.
Softness comes from construction. The Atmosphere seat and back cushions are built into the modules, so you press and smooth them instead of fluffing them. Gaia seat cushions are 9.4 inches (24 cm) thick, with fibre fill that settles in the seats you use most, so we suggest fluffing them weekly or every two weeks. Depth is not softness: a deep Atmosphere seat is firm, and a shallower Gaia seat is soft.
If you are tall or like to sit cross-legged, look at Atmosphere or Gaia XL. If you want a sink-in seat with a more upright back, look at Gaia. Our sofa seat depth and height guide compares every collection, and our Gaia comfort guide explains the build.
Which takes up more room in a living room?
Atmosphere takes up more floor space, and Gaia stands taller. A two-seater with two square arms is 81.1 inches (206 cm) wide on Atmosphere and 67.75 inches (172 cm) wide on Gaia, about 13.5 inches (34 cm) more, and the Atmosphere square back is about 6.5 inches (17 cm) deeper overall at 40.5 inches (103 cm) against about 34.0 inches (86 cm). Atmosphere seats are narrower, at 29.5 inches (75 cm) against 31.8 inches (81 cm) for Gaia Regular, but its square arms are 11.0 inches (28 cm) wide each.
The round Atmosphere narrows the gap: its arms are 9.1 inches (23 cm) wide, so a two-seater is 77.2 inches (196 cm) wide and 38.5 inches (98 cm) deep overall. Gaia has slim arms and a high back, about 39 inches (99 cm) tall against 29.1 inches (74 cm) for the Atmosphere square back, so it reads as the taller sofa.
If floor space is tight, start with Gaia Regular or the round Atmosphere, and check the route in with our guide to measuring stairs and doorways. Our guide to how many modules you need turns a wall length into a module list. In Cozey Studio, our online configurator, you can build either sofa one module at a time and read the overall dimensions at the bottom left of the screen.
Which is better for storage and overnight guests?
Atmosphere is the one to choose for either job, because Gaia has neither a storage seat nor a sleeper. The Atmosphere Storage version hides a compartment of 79.4 litres in each seat, corner and ottoman, and 74.5 litres in the long ottoman. The Sleeper version opens to a bed surface about 88.6 inches (225 cm) long and 59.1 inches (150 cm) deep, with three seats or with two seats and the sleeper ottoman, and individual sleeper modules can open on their own. A two-seater with the sleeper ottoman reaches about 98 inches (249 cm) into the room when open, so measure the space in front of the sofa. Regular, Storage and Sleeper modules cannot be mixed in one sofa, so choose the version first.
Gaia keeps storage to the storage ottoman, which measures 31.5 inches (80 cm) square and 21.3 inches (54 cm) high, with a hidden space inside of 26.8 inches (68 cm) square and 7.6 inches (19.3 cm) deep. Gaia has no sleeper module: its modules are seats, corners, a chaise and the storage ottoman. For a full-size or queen sleeper, see Neptune vs. Orian vs. Atmosphere Sleeper, and for where bedding goes, read our guide to sofa beds with storage.
How do the covers, fabrics and care compare?
At Cozey, both sofas have removable, machine-washable covers, and replacement covers let you change the colour later without replacing the sofa. Wash cold on a gentle cycle, air dry, and avoid bleach and high heat. On Atmosphere, the Cloud bouclé is also machine washable, but we advise spot cleaning it to maintain its look.
The fabrics overlap on three. Abrasion resistance is measured in Martindale double rubs, and a higher number means more rubs before wear shows.
How do the covers, fabrics and care compare?
| Fabric | Martindale | Atmosphere | Gaia |
|---|---|---|---|
| Aquaforte Velvet | More than 200,000 | Yes | Yes |
| Aquaforte | 78,000 | No | Yes |
| Performance Chenille | 48,000 | Yes | Yes |
| Performance Textured Weave | 54,000 | Yes | Yes, Mocha |
| Textured Weave | 54,000 | Yes | No |
| Performance Natural Weave | 18,000 | No | Yes |
| Corduroy | 15,000 | Yes, Storage and Sleeper versions | No |
| Bouclé (Cloud) | 15,000 | Yes, square back only | No |
In our own assessment, Aquaforte Velvet is the strongest choice for homes with pets, and Aquaforte and Performance Chenille are good choices too. Colours change, so check the product page and order free swatches. Our sofa fabric types guide and pet-friendly sofa guide go deeper, and our guide to keeping sofa cushions plump covers the fluffing routine.
What should I check before choosing between Atmosphere and Gaia?
Work through this list.
- Seat feel: decide whether you want a structured, medium-firm seat (Atmosphere) or a soft one you fluff every week or two (Gaia).
- Depth: measure how far you like to sit back, and compare 24.0 inches (61.5 cm) and 25.5 inches (65 cm) for Gaia with 27.5 inches (70 cm) and 29.5 inches (75 cm) for Atmosphere.
- Footprint: measure the wall and the walkway against the overall width and depth in the table, and allow for the chaise if you add one.
- Second job: if you want hidden storage or a guest bed, only Atmosphere offers them, in the Storage and Sleeper versions.
- Version: choose Atmosphere Regular, Storage or Sleeper, or Gaia Regular or XL, before you plan the layout, because types cannot be mixed.
- Fabric: pick from the table, and order swatches to judge the colour in your light.
Then test the build in Cozey Studio. If you would like help, you can also book a free design consultation.
Where do our other sofas fit, and what goes around them?
At Cozey, we make four modular sofa collections and two sofa beds, and Atmosphere and Gaia sit alongside the others:
- Ciello: a very soft sofa with a dedicated chaise and a storage ottoman. See Atmosphere vs Ciello and Ciello vs Gaia.
- Cassini: a curved sofa with a 26.5 inches (67 cm) seat depth and a 45-degree wedge module.
- Neptune and Orian: our two modular sofa beds, a full-size sleeper and a compact queen sleeper.
To compare all six, read which Cozey sofa is right for you.
Around either sofa, our wall systems add storage without floor space. Themis is a modular system of a shelf, a cabinet with sliding doors and a desk, 11.0 inches (28 cm) deep for the shelf and cabinet, and Altitude is a shallow wall shelf 9.5 inches (24 cm) deep. See our Themis guide and Altitude guide.
Our recommendation
At Cozey, we recommend choosing by what the sofa has to do, then by feel.
- Hidden storage in more than one seat: Atmosphere Storage.
- A guest bed in the living room: Atmosphere Sleeper.
- A structured seat that keeps its shape without fluffing: Atmosphere.
- A very deep seat: Atmosphere, with the round back at 29.5 inches (75 cm).
- A soft, loose-cushion seat with a high back: Gaia.
- A smaller footprint for the same number of seats: Gaia Regular.
- A chaise to stretch out on: Gaia, with a chaise 55.1 inches (140 cm) deep in Regular and 59 inches (150 cm) in XL. Atmosphere also offers a chaise on its Regular and Storage versions.
Whichever you pick, preview it in Cozey Studio and check the dimensions on the product page.
