Short answer: Our Gaia sofa is comfortable because of four things working together: a deep seat (61.5 cm or 24.2 inches in Regular, 65 cm or 25.6 inches in XL), a thick fibre cushion over a core of D35 high-density foam, an extra layer of D35 foam about 4 cm (1.5 inches) thick in the seat base, and a taller back with loose cushions. It is a soft, sink-in sofa for lounging, not a firm or upright one, and its covers are removable and machine washable.
A sofa can look inviting and still feel wrong after ten minutes. Softness, depth and back support each change how you sit, so it helps to know what is inside Gaia before you choose a size. This guide explains the comfort mechanics. For layouts, sizes and fabrics, read our Gaia sofa guide.

What makes the Gaia sofa comfortable?
Four design choices explain most of the feel: a deep seat, soft seat cushions over foam, a padded base, and a taller back with loose cushions. The table gives the number behind each one.
What makes the Gaia sofa comfortable?
| Measurement | Gaia Regular | Gaia XL | Why it matters when you sit |
|---|---|---|---|
| Seat depth | 61.5 cm (24.2 inches) | 65 cm (25.6 inches) | Room to sit back with your legs up |
| Seat width | 81 cm (31.8 inches) | 86 cm (33.9 inches) | More space per person in XL |
| Seat height | 54 cm (21.3 inches) | 54 cm (21.3 inches) | The same in both sizes |
| Overall height | About 99 cm (39 inches) | About 99 cm (39 inches) | Floor to the top of the back |
| Seat cushion thickness | 24 cm (9.4 inches) | 24 cm (9.4 inches) | A soft top layer |
| Chaise depth | 140 cm (55.1 inches) | 150 cm (59 inches) | Space to stretch out fully |
Our seat depth and height guide explains how we measure these numbers, and why seat depth and seat height should be read together.
How is the Gaia seat built from the base up?
Comfort comes from layers, so picture them from the frame upward.
- Frame: larch and plywood.
- Base layer: about 4 cm (1.5 inches) of D35 foam on top of the base. We added this layer in 2026, after customers told us they could feel the wooden frame through the seat on earlier versions. An older review may describe a version without it.
- Seat cushion: 24 cm (9.4 inches) thick, with fibre on both sides of a 6 cm (2.4 inch) foam core. The foam gives the seat its support, and the fibre gives it the soft top.
- Back and arm cushions: loose, 20 cm (7.9 inches) thick and fibre filled, so you can lean into them.
Gaia and Ciello share this seat construction, which is why our sofa comfort guide lists them as our two softest collections. Loose cushions soften as the fibre settles with use, so plan to fluff them every week or two and rotate the seat cushions, as described in our guide to keeping sofa cushions plump.
Why does a deep seat feel so relaxed?
Seat depth decides what you can do with your legs. On a deep seat you can sit back with your legs up, sit sideways in a corner, or curl up. On a shallow seat you may have to choose between leaning back and keeping your feet on the floor.
Gaia Regular is 61.5 cm (24.2 inches) deep, deeper than Ciello Regular at 55 cm (21.7 inches). Gaia XL is 65 cm (25.6 inches) deep, and Ciello XL is deeper at 67 cm (26.4 inches). On Gaia, the step from Regular to XL adds about 3.5 cm (1.4 inches) of depth, and a comparable three-seater is about 18 cm (7 inches) wider overall.
Deeper is not always better. If the seat is too deep for your legs, you may not be able to rest your feet on the floor while keeping your back against the cushion. That is general advice, and it is why we suggest the fit test below.
How much back and arm support does Gaia give?
Our product page describes Gaia as having a taller backrest and higher back cushions than Ciello, at an overall height of about 99 cm (39 inches). That gives your back and shoulders a place to rest when you sit back. Gaia has one back style, with slim arms and French seam cushions. Ciello offers Original and High Angled backs, and the High Angled back leans further back.
If you want to change the back angle to suit your body, Ciello gives you more choices. If you prefer a tailored back that holds you upright while the seat stays soft, Gaia is the simpler pick. Because the back cushions are loose, they shift a little when you lean.
Which uses is Gaia best for?
Gaia suits relaxed, everyday sitting. The table shows how the build helps in each case and what to add.
Which uses is Gaia best for?
| Use | Why Gaia works | What to consider |
|---|---|---|
| Lounging and reading | Deep seat, soft cushions, taller back | XL for the deepest seat, or add a chaise |
| Napping | A soft seat and a long chaise let you stretch out | Gaia XL with the 150 cm (59 inch) chaise. Gaia is not a sofa bed |
| Watching TV | You can sit back with your legs up or sit sideways in a corner | A sectional with a corner seat |
| Putting your feet up | The storage ottoman is 54 cm (21.3 inches) high, the same as the seat | The ottoman stands on its own, so you can move it |
| Kids and busy households | Covers are removable and washable. Each seat holds up to 159 kg | Chenille or Aquaforte fabrics, and the care routine below |
For kids, we advise against jumping on any sofa, and we suggest securing the sofa to the wall with an anti-tip kit to reduce the risk of tipping.
What is Gaia not?
Gaia is not a firm or upright sofa. If you prefer a firm seat and a structured sitting position, our comfort guide points to Neptune as our firmest collection, and to Cassini and Atmosphere as more structured options.
It also asks for a little care. The loose cushions need fluffing, the seat settles with use, and the cushions arrive vacuum-packed and can take up to two weeks to expand fully. If you want a soft sofa but like to adjust the back, Ciello may suit you better, and our Ciello vs Gaia guide compares the two side by side.
How do the covers affect comfort and care?
The covers are removable and machine washable, and they include the seat cushions, back cushions, upholstered arms and base. We suggest cold water, a gentle cycle, air drying, no bleach and no high heat. Compatible replacement covers let you change the colour without replacing the sofa, and the cushions underneath are the same whichever fabric you choose.
Gaia comes in Performance Natural Weave, Performance Textured Weave, Performance Chenille, Aquaforte and Aquaforte Velvet, with Martindale counts from 18,000 to more than 200,000. In our own assessment, Aquaforte Velvet and Performance Chenille are good choices for homes with pets. Our guides to sofa fabric types and washable sofas for pets and kids go into more detail, and you can order free swatches before you decide.
A ten-minute sit test for Gaia
Soft sofas are easiest to judge by sitting, so use the numbers as a checklist.
- Sit all the way back. Can you rest your feet where you want them, with your back on the cushion?
- Try your usual posture: upright, legs up, curled up or reclined.
- Check the back height against your shoulders, because Gaia has one back style.
- If two people share the sofa and differ in height, compare Gaia Regular with a shallower sofa and an ottoman.
Our product page lists a 30-day free trial and a 5-year warranty (see our warranty page), so you can also test the sofa at home.
Our recommendation
Pick by how you sit.
- You want a soft seat and a back that holds you upright: Gaia Regular.
- You like to stretch out, nap or curl up: Gaia XL, with a chaise or storage ottoman.
- You want to adjust the back angle or want the deepest seat: Ciello, in Original or High Angled, or Ciello XL.
- You prefer a firm, upright seat: look at the firmer collections in our comfort guide.
- You have kids or pets: Gaia in Aquaforte Velvet or Performance Chenille, with washable covers.
