How to Choose the Right Sofa: An Interior Designer’s Guide

A sofa is one of the biggest furniture investments you’ll make in your home, yet it’s often chosen based on looks alone.

Clients regularly send me beautiful inspiration images and ask, “Which sofa should I buy?” But before we talk about fabric, colour or shape, I always ask:

How do you want to use it?

The best sofa for entertaining friends can be very different from the one you want to curl up on for a Netflix marathon. Here are the key things I consider when choosing a sofa for our interior design projects.

1. Sofa Depth: Entertaining or Lounging?

Sofa depth has an enormous impact on comfort.

A shallower sofa encourages a more upright sitting position. It feels supportive, conversational and is easier to get in and out of, making it a great choice for formal living rooms and entertaining spaces. It can also be more comfortable for shorter people and older family members.

A deep sofa, on the other hand, is designed for lounging. Sofas around 900–1000mm deep create that relaxed, sink-in feeling that's perfect for family rooms, movie nights and putting your feet up.

Neither is better. The question is whether you want your sofa to support conversation or encourage lounging.

2. Foam vs Feather Sofa Cushions

What’s inside your sofa matters almost as much as how it looks.

Foam cushions

Foam holds its shape well and requires very little maintenance. It creates a structured, tailored appearance and is ideal if you like your sofa to look neat every time you walk into the room.

The compromise is that you lose some of the luxurious softness of feather.

Feather cushions

Feather creates a relaxed, soft and beautifully lived-in sofa. It's incredibly comfortable, but it requires more maintenance.

Cushions need regular fluffing and reshaping as the feathers naturally settle and compress. For this reason, I rarely specify fully feather-filled sofas for formal living rooms.

Feather-wrap cushions

For many of our clients, a foam core wrapped in feather is the sweet spot.

You get the support and structure of foam with much of the softness of feather. You can also combine different inserts — perhaps a supportive foam seat with softer feather-wrap back cushions.

There is no universal answer. It comes down to how you like your sofa to feel — and how much fluffing you're prepared to do.

3. Consider the Shape of Your Sofa

The shape of your sofa doesn't just change how your living room looks. It changes how people use the space.

A classic three-seater works beautifully with one or two occasional chairs and is often my preference for entertaining spaces. Multiple seating options create a more conversational furniture arrangement.

Curved sofas feel softer and more sculptural. They can become a feature within the room while also making a seating arrangement feel less rigid.

Modular sofas are ideal for relaxed family living. They offer generous seating, work beautifully for movie nights and, depending on the design, can often be reconfigured as your needs change.

4. What About Recliner Sofas?

This may be controversial, but I'm generally not a huge fan of motorised recliner sofas in a main living room.

The technology is improving, but aesthetically, many still have some catching up to do.

If putting your feet up is important, a beautifully designed armchair with an ottoman can often give you the same comfort while maintaining a more refined look.

A dedicated media or TV room is another story. In those spaces, comfort can absolutely win.

5. Use Cushions and Throws to Add Comfort

Remember that the sofa itself isn't your only opportunity to introduce softness.

Even a structured foam sofa can feel incredibly inviting when layered with feather-filled scatter cushions, oversized cushions and a beautiful wool or textured throw.

These finishing layers allow you to introduce colour, texture and personality while making a more tailored sofa feel relaxed.

Before You Buy a Sofa, Ask Yourself This

Do I want my sofa to look perfect, feel perfect, or strike a balance between the two?

Every sofa involves some compromise.

A deep feather sofa may be wonderfully comfortable but require regular maintenance. A structured foam sofa may always look immaculate but won't give you the same sink-in feeling.

The trick is understanding which compromises you're happy to make before you fall in love with the most beautiful sofa in the showroom.

Because ultimately, the best sofa isn't simply the one that looks good.

It's the one that supports the way you live.
