Sofa Comfort Guide: Feather, Foam or Pocket Coils?
You will sit on your sofa most evenings for years, so the seat matters as much as the shape or the cover. Two sofas can look alike in a photo and feel very different once you sit down. Of all the things that separate the types of sofa on the market, the seat cushion makes the biggest difference to how a sofa feels.
Every Superba sofa uses one of three seat builds: Sink-in Comfort, Soft Support Comfort and Rich Feel Comfort. We don't rank them. Each one suits a different way of sitting. This guide shows you what goes inside each seat, how it feels, how to look after it and which Superba sofas use it, from our leather sofas to our modular and small sofas.
- Sink-in Comfort: feather and fibre over foam, no springs. You sink in and the cushion hugs you.
- Soft Support Comfort: fibre-wrapped foam over pocket coils. Soft on top, steady underneath, no feathers.
- Rich Feel Comfort: feather and fibre over foam and pocket coils. A plush top with springy support below.
What goes inside a sofa seat
Every seat cushion is a stack of layers. Change one layer and the whole seat feels different. These are the parts you will see in our seat diagrams:
- Quilted lining: a soft cotton down-proof lining, stitched into channels. It keeps the feather and fibre spread evenly and stops feathers working their way through the cover.
- Feather and fibre mix: half duck feather, half fibre, ethically sourced. Feather gives the seat its soft, sink-in feel. Fibre adds body and helps the cushion bounce back after you get up.
- High-performance foam: the core of the cushion. It holds the seat's shape and carries your weight.
- Fibre wrap: a layer of fibre wrapped around the foam. It softens the first touch and rounds off the edges of the cushion.
- Pocket coils: small springs, each sewn into its own fabric pocket. Each coil moves on its own, so the seat responds to where you sit and gives a gentle lift.
A rule of thumb: the more feather near the top, the softer and more relaxed the seat. Coils underneath add support and spring.
Comfort also depends on seat depth and the height of the back. Our sofa dimensions guide explains standard sofa dimensions and how to measure your room.
Sink-in Comfort: feather and fibre over foam
What's inside: a soft cotton down-proof quilted lining filled with an ethically sourced feather and fibre mix, over a high-performance foam base. No springs.
How it feels: you sink into the seat as you sit down and the cushion settles around you. It feels relaxed and soft, the kind of seat you curl up on with a book or stretch out on for a film.
Looking after it: feather moves as you sit, so the cushions will take your shape. Plump and turn them every few days to keep them full and even. Over time they take on a soft, slouchy look, which is part of the charm.
Choose Sink-in Comfort if you:
- like to lounge, tuck your feet up or nap on the sofa
- want a soft, relaxed look over a crisp, tailored one
- don't mind a quick plump of the cushions now and then

Soft Support Comfort: fibre-wrapped foam over pocket coils
What's inside: high-performance foam wrapped in a fibre lining, over a pocket coil suspension system and a high-performance foam base. No feathers.
How it feels: soft on the first touch, with even, steady support underneath. You sit on the cushion more than in it, and the coils give a light spring when you sit down and stand up.
Looking after it: the foam keeps its shape, so the cushions stay neat and tailored with very little effort. A quick straighten is usually all they need.
Choose Soft Support Comfort if you:
- sit upright to chat, eat, work or watch TV
- like a crisp, tidy sofa that looks the same at the end of the day as it did in the morning
- want a seat that is easy to get in and out of
- prefer a feather-free sofa

Rich Feel Comfort: feather and fibre over foam and pocket coils
What's inside: a soft cotton down-proof quilted lining filled with an ethically sourced feather and fibre mix, over high-performance foam and pocket coils.
How it feels: the feather top gives as you sit, then the foam and coils hold you. You get the plush feel of feather on top with springy support underneath, so the seat stays comfortable through a long evening.
Looking after it: the feather layer moves as you sit. Plump the cushions every few days to keep them full and even.
Choose Rich Feel Comfort if you:
- love the softness of feather but want more support underneath
- spend long stretches on the sofa and switch between sitting up and lounging
- share the sofa with people who like different seats

How to choose your seat comfort
Ask yourself these four questions. Your answers will point you to one comfort, or two at most.
0 of 4 answered
Your comfort appears here as you go.
1. How do you sit?
If you curl up, lie down or sit with your legs tucked under you, look at Sink-in Comfort. If you sit upright with your feet on the floor, look at Soft Support Comfort. If you do a bit of both, Rich Feel Comfort gives you a soft top with support below.
2. Who uses the sofa?
Think about everyone in the house. A seat that is easy to get up from suits older family members and anyone with a sore back or knees, and that points to Soft Support Comfort. For a family sofa that hosts film nights and long weekends, Sink-in or Rich Feel Comfort on a corner or modular sofa gives everyone room to stretch out.
3. How much space do you have?
In a small flat, a compact two-seater or a small modular you can add to later works best. Every comfort feels the same on a small sofa as on a large one, so choose the seat first and the size second.
4. How much looking after do you want to do?
Feather seats need a plump every few days. If you would rather skip that, choose Soft Support Comfort, which keeps its shape on its own.
Choose your comfort, then your cover and shape
Once you know which seat you like, pick the cover and the shape around it. Each cover changes the look and the touch of the sofa:
- Leather sofas: our luxury leather sofas age with you and develop a patina over the years. A feather seat on a premium leather sofa gives you a relaxed, lived-in look.
- Linen sofas: a natural, breathable fibre with a soft texture. Linen pairs well with the relaxed shape of a feather seat.
- Velvet sofas: deep colour and a soft pile. A tailored foam seat keeps velvet looking smooth.
- Fabric sofas: the widest choice of colours and textures for everyday family life.
Then choose the shape:
- Small sofas: modern small sofas for flats and smaller living rooms.
- Corner sofas: more seats for families and open-plan rooms.
- Modular sofas: pieces you can rearrange or add to as your home changes.

Caring for your sofa cushions
A few minutes a week keeps any seat looking and feeling its best:
- Plump feather cushions every few days. Lift each one, press the sides together a few times and drop it back in place.
- Turn and rotate cushions every week or two so they wear evenly. Swap the seat you use most with one you use least.
- Straighten foam cushions when they slide forward. They keep their shape and need little else.
- Keep the sofa out of strong sun to protect the cover, whatever it is made of.
Look after the cushions and the frame and a well-made sofa should last you many years. Our sofa care guide covers cleaning by material, from fabric and linen to velvet and leather, and our care booklet has the full details.
Frequently asked questions
What is the most comfortable type of sofa?
That depends on how you sit. Loungers tend to love Sink-in Comfort, upright sitters prefer Soft Support Comfort, and Rich Feel Comfort sits between the two. Use the questions above to find your match.
Which seat feels the firmest?
Soft Support Comfort feels the most structured, because foam and coils sit right under the fibre wrap. Sink-in Comfort feels the softest.
What is the best type of sofa for a family?
A corner or modular sofa gives the most seats. Pair it with Rich Feel Comfort if your family switches between sitting up and lounging, or Soft Support Comfort if you want cushions that stay neat with little upkeep.
Are modular sofas comfortable?
Yes. Comfort comes from seat depth, cushion fill and the frame, not from whether a sofa is modular. Oli Modular has Soft Support Comfort and Elo has Rich Feel Comfort.
Do feather cushions go flat?
Feather moves as you sit, so the cushion shows where you sat. Plump it and it springs back. The foam core inside our feather seats keeps the cushion's shape underneath.
Do any of your sofas have no feathers at all?
Yes. Every sofa with Soft Support Comfort is feather-free: Oli, Oli Plus, Oli Modular, Jasmine, Caro, Jade, Milo, Theo, Valenti and Edgar.
What are pocket coils?
Small springs, each sewn into its own fabric pocket. Each one moves on its own, so the seat supports you where you sit without rolling you towards the person next to you.
How long should a sofa last?
A well-made sofa should last ten to fifteen years or more with good care. Our frames come with a lifetime guarantee.
Can I try the comfort before I buy?
Yes. Every Superba sofa comes with a 30-day home trial, so you can sit on it in your own living room. See our delivery and returns policy for the details.
