Short answer: Cozey's modular sectionals are customizable from the first module: you choose a collection, the modules and chaise side, the arms and the fabric, then preview the build in Cozey Studio before you order. You can add or rearrange modules later within the same collection.
A sectional is hard to judge from a photo, and a modular one adds choices: size, shape, fabric and what you might change later. This page gives the buying decision in order and links the deeper guides instead of repeating them.

Where can I shop for customizable sectionals online?
At Cozey, we sell four modular sofa collections online, Ciello, Gaia, Cassini and Atmosphere, and each is built from separate modules that you choose and arrange. Our collections at a glance:

How do I customize a sectional, step by step?
At Cozey, you customize a sectional in six steps, big decisions first.
1. Pick a collection. Choose by feel and seat depth from the table above.
2. Choose the modules and the chaise side. Ciello, Gaia and Atmosphere offer a left, right or double chaise, while Cassini curves with wedge modules instead.
3. Choose arms and back style. For example, Ciello has two back and arm styles and Atmosphere has a square or round back.
4. Choose the fabric and colour. See the fabric section below, and order free swatches first if you can.
5. Preview the build in Cozey Studio. Check the shape and the overall size on screen.
6. Order, then add or reconfigure later. Modules ship in separate boxes, and you can add to the sectional as your room changes. Every order also has a 30-day risk-free trial, explained in our delivery and returns checklist.
Where can I buy a modular sectional I can reconfigure later?
At Cozey, every sofa collection is modular, so you can add, remove and rearrange modules within compatible configurations. A reversible chaise is a chaise module that can be attached to either the left or right side of the sectional, so you can change its orientation if you move or rearrange your room.
Check the limits before you plan a future layout. In Ciello and Gaia, Regular and XL modules cannot be mixed. In Atmosphere, regular, storage and sleeper modules cannot be combined, and you cannot upgrade a sofa from one type to another by swapping seats. A module from one collection should not be assumed to fit another, and arms are handed in some collections, so confirm the arm modules too.
Our guides to what a modular sofa is and the difference between a sofa and a sectional explain how modules connect.
Which modular sectionals come with sizing guides for proper measuring?
At Cozey, all four collections are covered by our sizing guides. Our guide to how many modules you need lists each collection's module widths, and our sectional size guide, guide to choosing a sofa size and guide to measuring stairs and doorways cover the room and the route in.
Two widths to start from, each a sum of module widths with no gap:
- Cassini, armless: a two-seater is 52.8 inches (134 cm) wide and a three-seater is 79.1 inches (201 cm).
- Atmosphere Regular, armless: a three-seater is 88.6 inches (225 cm) wide, or 110.6 inches (281 cm) with two square arms.
Before you order, work through this list:
- Both legs of the L: measure each wall the sectional will follow. As general advice, keep walking paths at least 30 inches (76 cm) clear, and 36 inches (91 cm) is more comfortable.
- Chaise side: sketch the room and check that the chaise does not block a door or vent.
- Overall size: confirm the final footprint in the configurator before you order.
Which fabrics and colours can I choose?
At Cozey, you choose the fabric after the shape, and the choice depends on the collection. Abrasion resistance is measured in Martindale double rubs, and a higher number means a more durable surface.
Which fabrics and colours can I choose?
| Fabric | Martindale double rubs | Offered on |
|---|---|---|
| Aquaforte Velvet | More than 200,000 | Ciello, Gaia, Cassini, Atmosphere |
| Aquaforte | 78,000 | Ciello, Gaia |
| Performance Chenille | 48,000 | Ciello, Gaia, Cassini, Atmosphere |
| Performance Textured Weave | 54,000 | Ciello, Gaia, Atmosphere |
| Performance Plain Weave | 90,000 | Ciello |
| Performance Natural Weave | 18,000 | Gaia |
| Corduroy | 15,000 | Ciello, Atmosphere |
| Bouclé | 15,000 | Atmosphere |
Aquaforte Velvet is the fabric to look at first if the sofa will see heavy use, and it now comes in eight colours; our Aquaforte Velvet colours guide shows them. In our own assessment, Aquaforte Velvet and Performance Chenille are good choices for homes with pets. Colours can change, so check the product page for what is available.
Judge a colour in your own light with free swatches. Replacement covers are available for all four sofas, so you can change the colour later. Our guide to choosing a sofa colour helps you narrow it down.
How does Cozey Studio help me preview a customized sectional?
Cozey Studio is our online configurator where you design a sectional from our collections and see it before you order. You start with a first module and add one at a time, and at each step it offers only the modules that can attach next.
For this decision, Studio does three jobs. You can add, delete or replace any module until the shape suits your wall, such as a longer row or one extra seat. The overall dimensions appear at the bottom left of the screen, so you can compare the design with your measurements. And you choose the arm at each end and the cushions seat by seat, so each end can differ.
Our product pages have a step-by-step selector that is quicker when a ready-made layout already fits. Our Cozey Studio guide walks through every step.
Where can I find tables that match modular furniture?
At Cozey, several of our tables are modular too, and all five below come in Oak or Walnut.
Where can I find tables that match modular furniture?
| Table | Size | Why it suits a modular sofa |
|---|---|---|
| Stella coffee table | 23.5 inches (60 cm) square, 18.5 inches (47 cm) high closed, lifting to 26.4 inches (67 cm) | Start with one module and link more later, like the sofa |
| Arca | 21.5 inches (55 cm) square, 13.8 inches (35 cm) high | Curved has hidden storage and fluted has open storage; two joined make a 43.4 inches (110 cm) coffee table |
| Ombra | Coffee table 43.3 inches (110 cm) by 21.5 inches (55 cm) by 13.3 inches (33.9 cm) | Two ottomans nest under the top and pull out as extra seats |
| Eclipse | Coffee table 31.5 inches (80 cm) across, 15.4 inches (39 cm) high | A round top for a room approached from several sides |
| Tessella | 67.6 inches (171.7 cm) long, 27.0 inches (68.5 cm) deep, 16.0 inches (40.7 cm) high | Our longest coffee table, designed for a wide three-seat sofa |
As general advice, leave 14 to 18 inches (36 to 46 cm) between the sofa and the coffee table, and allow for the chaise reaching into the room. Our guides cover each table: Stella, Arca, Ombra, Eclipse and Tessella. For choosing between them, read how to choose a coffee table and how to pair a sofa, accent chair and coffee table.
What can go on the wall beside a modular sectional?
At Cozey, we make two wall systems that grow in the same way as the sofa. Themis is a modular system of three units, a shelf, a cabinet with sliding doors and a desk, each 32.0 inches (81.3 cm) wide and 24.0 inches (61 cm) high. The shelf and cabinet are 11.0 inches (28 cm) deep and can be wall-mounted or freestanding. Each unit holds 50 lb (23 kg).
Altitude is a shallow wall shelf, 32.0 inches (81.3 cm) wide, 9.5 inches (24 cm) deep and 32.0 inches (81.3 cm) high per unit, in a set of one, two or three, with a storage cabinet that slides between two shelves and closes with a magnetic push latch. Both hang on the wall with the hardware in the box.
Measure the wall against your sectional first, so the shelves clear the sofa and the chaise. See our Themis guide, our Altitude guide and our guide to planning a shelving wall.
Our recommendation
At Cozey, we suggest choosing the shape first and the details second. Cozey Ciello suits you if you want a soft, deep seat and a chaise, Gaia if you want a soft seat with a more upright, high back, Cassini for a curved, low layout, and Atmosphere for our deepest seat or hidden storage.
Then preview the build in Cozey Studio, order free swatches, and add tables and wall storage once the sofa is in place.
