Sofa Back Styles: Loose, Attached, Tight and With a Headrest

A plain guide to sofa back construction and how it applies to every Cozey collection: which backs have loose cushions, which are built in, which come in more than one height, and which accept a headrest.

Short answer: Cozey's Ciello, Gaia and Orian have loose back cushions that lift off. Our Atmosphere, Cassini and Neptune have backs built into the module. Only Neptune offers an optional headrest.

The back decides how a sofa feels when you lean, how tall it looks and how much upkeep it needs. This page explains the general back styles, then shows which one each of our collections uses, with figures you can compare in a table.

What are the main sofa back styles?

Four terms come up when you shop for a sofa, and they describe how the back is built, not how soft it is.

  • Loose back: the back cushions are separate and lift off the frame, so you can reposition, fluff or wash them.
  • Attached back: the back cushions are fixed to the frame, often sewn or fastened on, so they stay where they are put.
  • Tight back: the back is one smooth upholstered surface with no cushion to move.
  • Headrest: an extra piece above the back for the head and neck, either built into the sofa or added as an option.

These are general sofa terms, and our modular sofas do not map onto them one to one. All of our sofas are built from modules, so each back is its own module that connects to a seat. The more useful question for our collections is whether the back cushion is loose or built in. A built-in back sits between an attached and a tight back: its cushion does not lift off the way a loose one does.

Which Cozey sofas have loose back cushions?

At Cozey, three collections have loose back cushions, and each gives a different lean.

  • Ciello: soft, loose back and arm cushions in two styles. The Original back is 33 inches high on Regular and 34.3 inches on XL, and the High Angled back is 37 inches high and leans further back. We introduced High Angled after customers told us the Original back felt low. Our Ciello guide has the full figures.
  • Gaia: one back style, taller than Ciello's Original, with loose cushions that are 7.9 inches thick and an overall height of about 39 inches. Our Gaia guide covers it, and Ciello vs Gaia compares the two.
  • Orian: a lower back, 28.7 inches high, with soft, loose back cushions over a firm seat. It has no headrest option. See our Orian guide.

Loose backs feel relaxed because the cushion gives when you lean, and you can push it into the shape you like. The trade-off is upkeep: on Ciello and Gaia we recommend fluffing about every week or two, and a loose cushion can shift out of place. Our guide to keeping sofa cushions plump covers the routine, so we do not repeat it here.

Which Cozey sofas have backs built into the module?

At Cozey, three collections have backs where the cushion is part of the module, so there is nothing to lift off and reposition.

  • Atmosphere: the seat and back cushions are built into the modules, and the backs use D30 foam. You choose a square back, 29.1 inches high with a seat depth of 27.5 inches, or a round back, 30.9 inches high with a seat depth of 29.5 inches. Loose lumbar and decorative cushions are optional extras. Our Atmosphere guide explains the choice.
  • Cassini: layered-foam backrests that all share one height, 27.8 inches, so the sofa looks low and even. The seat depth is 26.5 inches and the seat height is 17 inches. See our Cassini guide.
  • Neptune: integrated seat and back cushions in layered foam, a back 33.9 inches high, which is the tallest of our sofa beds, and a lumbar pillow with each seat. The seat depth is 22.5 inches. Our Neptune guide has the rest.

Built-in backs feel more structured, and they hold their shape without a fluffing routine. You press and smooth the surface by hand, and you fluff only the loose lumbar or decorative cushions. If you want a firmer lean and less upkeep, this is the group to start with.

Which Cozey sofa has a headrest option?

Neptune is the only Cozey collection with an optional headrest. It is a separate extension that slides on top of the back and connects with two metal spokes, so it sits between the back cushion and the backrest. You can add one to a seat, and corner seats have their own corner headrests.

We offer the headrest for extra upper-back and neck support when you lean back to read, work or watch television. That is a comfort option, not medical advice, and it is easiest to judge by sitting in one. It is a good match for the upright, firm feel that Neptune already has.

Our other sofas do not have a headrest option. Orian has no headrest, and on Ciello, Gaia and Atmosphere the way to get more back support is a taller back: Ciello High Angled or the Atmosphere round back.

How do the back styles compare across our collections?

The first table shows how each back is built and cared for. The second shows the heights and depths to compare before you choose.

Heights run from the floor to the top of the back and are taken from each collection's product guide, so check the exact module on its product page. Seat depth is measured with the back cushion in place, so a different back changes it slightly. For how seat depth and height work together, read our seat depth and height guide.

How does the back change how a sofa feels and what you need to do?

Softness and construction are linked. Our loose-back sofas have the softest backs: Ciello and Gaia are the softest, and Orian pairs soft back cushions with a firm seat. Neptune has the firmest back. Our sofa comfort guide ranks the backs from softest to firmest, so this page does not repeat the ranking.

Care follows the same split. Loose backs need an occasional fluff and reshaping, and built-in backs need a press and smooth. All six collections have removable cushion covers, and the cover care steps, such as washing cold on a gentle cycle and air drying, are on each product guide and in our guide on how often to wash sofa covers.

What should you check before you choose a back style?

Work through this list. The first two points are general advice, not a product specification.

  • Sit back and look at the height: the top of the back should land where you want to rest your head or shoulders, so compare the back height in the table with your own seated height.
  • Pick loose or built in: loose is softer and easier to reshape, and built in is firmer and needs less upkeep.
  • Choose the height or shape: Ciello offers Original or High Angled, and Atmosphere offers square or round.
  • Decide on a headrest: only Neptune offers one, so choose it if neck support matters to you.
  • Preview the build: Cozey Studio shows your sofa on screen with its overall dimensions before you order, and our Cozey Studio guide explains the steps.

Our recommendation

At Cozey, we suggest choosing the back by how you lean. For a soft, relaxed lean, choose a loose back: Ciello with the High Angled back if you want more support, Gaia for a taller back, or Orian for a firm seat and a lower, softer back.

For a firmer lean with less upkeep, choose a built-in back: Atmosphere, Cassini or Neptune. If you want a headrest, choose Neptune. Our guide on which Cozey sofa is right for you helps if you are still undecided.

Frequently Asked Questions

A loose back sofa has back cushions that lift off the frame, so you can fluff, reposition and wash them, and they feel softer but can shift. A tight back sofa has one smooth upholstered back with no cushion to move, so it looks neater and holds its shape. At Cozey, our modular backs fall into two groups instead: loose cushions on Ciello, Gaia and Orian, and cushions built into the module on Atmosphere, Cassini and Neptune. A built-in back is the closer match to a tight back.


Cozey's Ciello, Gaia and Orian have loose back cushions. Ciello and Gaia have soft, loose back and arm cushions, and we recommend fluffing them about every week or two. Orian pairs a firm seat with softer back cushions that you can move to change how upright you sit. The back cushion covers are removable on all three, and on Orian the arm and base covers are fixed. Loose cushions can shift, so expect to pat them back into place now and then.


Cozey's Neptune is the only sofa with an optional headrest. It is a separate extension that slides on top of the back and connects with two metal spokes, sitting between the back cushion and the backrest, and corner seats have their own corner headrests. We offer it for extra upper-back and neck support when you lean back to read, work or watch television. It is a comfort option, not medical advice, so sit in a Neptune if you can before you decide.


At Cozey, we do not offer a headrest for Ciello, Gaia, Atmosphere, Cassini or Orian. Neptune is the only collection with one. If you want more back support on another sofa, the options are a taller back: Ciello offers the High Angled back at 37 inches high, against 33 inches for the Original on Regular, and Atmosphere offers the round back at 30.9 inches high, against 29.1 inches for the square. Gaia already has a taller back, at about 39 inches overall height.


At Cozey, back heights range from 27.8 inches on Cassini to 37 inches on Ciello High Angled. Orian is 28.7 inches, the Atmosphere square back is 29.1 inches and its round back is 30.9 inches. Ciello Original is 33 inches on Regular and 34.3 inches on XL, Neptune is 33.9 inches, and Gaia is about 39 inches overall. Heights run from the floor to the top of the back, so check the exact module on its product page.


Yes, at Cozey, the cushion covers are removable on all six collections. On Ciello and Gaia the back cushion covers are removable and machine washable. Orian and Neptune have removable seat and back cushion covers, but their arms and bases have fixed upholstery. Atmosphere covers on the seats, backs and arms are removable, and each Cassini backrest has its own cover. For care, we advise washing cold on a gentle cycle and air drying, and avoiding bleach and high heat.


At Cozey, a built-in back needs the least upkeep. Atmosphere, Cassini and Neptune have backs that you press and smooth by hand, and you only fluff the loose lumbar or decorative cushions, such as the lumbar pillow that comes with each Neptune seat. Loose backs on Ciello and Gaia need fluffing about every week or two, and Orian back cushions may need occasional fluffing. Our guide to keeping sofa cushions plump explains how to fluff and rotate.
