The sofa set models of 2027 are less about three matching pieces and more about a composed group: one main sofa, two armchairs, and often a Chesterfield or a curved sofa mixed with a cleaner modern shape. Long, low and deep sofas, rounded forms and warm, muted leathers were among the clearest themes at the Salone del Mobile in Milan in April 2026, where many 2027 collections took shape.
Below we go through five set formats, each shown with a Sitdesign model made in our factory in Büyükçekmece, Istanbul. For the wider picture of shapes and colours, read our sofa trends for 2027 from Milan Design Week; this guide is about how the pieces work together as a set.
From 3+2+1 to a composed set
For a long time a sofa set meant a three-seater, a two-seater and an armchair in the same model and the same leather. That format still works, especially in long rectangular rooms and in family homes where everyone wants a sofa seat. What changes in 2027 is the starting point: instead of choosing one model in three sizes, people choose the main sofa first and then decide what sits opposite it.
- Sofa and two armchairs: the most flexible format, and the one that suits 2027 best.
- Two sofas facing (3+3): for large rooms and for homes that host often.
- Classic 3+2+1: practical for family rooms, fresher when the armchair is a different model or colour.
The practical difference is flexibility. A 3+2+1 fixes the layout; a sofa with armchairs can be rearranged, and the armchairs can later move to a bedroom or a study. For the measurements behind each layout, see our guide to sofa set configurations: 3+2+1, 3+3 and corner layouts.
A curved sofa with two armchairs
Rounded, sculptural forms were one of the strongest ideas in Milan, and a curved sofa suits the sofa-plus-armchairs format well. The soft line of the back lets the armchairs sit at a slight angle, so the group reads as a circle around the coffee table rather than a straight row.
Janette Curved sofa in red leather, with two cream armchairs as the other seats of the set.
The Janette Curved sofa shows the idea: a red sofa with a cream armchair on each side and two round coffee tables of different heights in the middle. The armchairs are not the same colour as the sofa. The set is held together by proportion and by a warm palette, not by repetition, which is exactly why it looks current. Two smaller tables instead of one large one also follows Milan, where coffee tables were often shown in pairs or matching sets.
A Chesterfield beside a modern sofa
Mixing a buttoned Chesterfield with a plain, modern sofa is one of the most useful ideas for 2027, because it lets a classic piece live in a contemporary room without turning the room into a period set.
The white Nottingham sofa with a burgundy Chesterfield sofa and armchair.
In the image, the white Nottingham sofa sits at a right angle to a burgundy Chesterfield sofa and armchair. The pairing works through contrast: deep buttoning and rolled arms on one side, plain upholstery and loose cushions on the other, and a clear light-and-dark difference in colour.
- Let one piece lead: usually the Chesterfield, in the darker or stronger colour.
- Keep the modern sofa simple: straight lines and no buttoning, so the two do not compete.
- Repeat one link: a leather tone in a cushion, or the same metal finish on the side tables.
Our guide to the Chester sofa set covers the classic version in more detail, and the full range is in our Chesterfield sofas collection.
Two armchairs instead of a second sofa
In many living rooms the second sofa is the piece that blocks the walking route or the view to the window. A pair of armchairs has less visual weight, keeps the room open and gives two people the best seats for conversation. In 2027 sets this pairing appears both inside a full set, with the sofa on one side and two armchairs opposite, and on its own by a window or in a reading corner.
A pair of Jackson armchairs: a conversation corner without a second sofa.
The Jackson armchair is shown here as a matching pair, angled towards each other with small round tables between them. A matching pair looks calm and deliberate; two different models can work too, but then keep them close in height and colour. Choose armchairs you can sit in for a whole evening, not only accent chairs, if they replace a sofa. More models are in our armchair collection.
Long, low and deep
The 1970s influence seen in Milan shows most clearly in proportions: oversized, low-profile sofas, some of them modular and several metres long, while slim, upright silhouettes were largely absent. In a set, a sofa like this becomes the anchor, and the other pieces can be smaller and lighter.
Rosalinda sofa in brown leather, with a darker armchair as its counterpoint.
The Rosalinda sofa shows the effect in brown leather: a long seat, buttoned detailing on the back and arms, and a single dark armchair by the fireplace instead of a second large piece. A deeper seat changes how you sit, so try the depth in our showroom or compare it with a sofa you already like before you order. Custom dimensions are available on request, so length and depth can be adjusted to the wall. All our upholstered frames are kiln-dried beech, and the seats combine sprung seating with high-resilience (HR) foam. If your room allows an L or U shape, the modular idea is easiest to follow with a corner piece from our sectional sofa collection.
Matching or complementary upholstery
The last decision is whether every piece wears the same leather. A fully matching set is calm and formal. A complementary set, with two or three related colours, looks more relaxed and is closer to how the 2027 collections were styled.
Manchester sofa in black leather with a tan sofa: complementary colours rather than a matching set.
The black Manchester sofa with a tan sofa beside it is a clear example: two different shapes and two different leathers, tied together by one long, low coffee table. The colours shown for 2027 lean warm and muted: browns, toasted tones, ochre, muted greens and some orange upholstery. For tables and storage around the sofa, see coordinating a living room set: sofa, tables and storage.
- Matching: the same leather on every piece, best for formal rooms and symmetrical layouts.
- Tonal: one colour family in different shades, for example a cognac sofa with sand armchairs.
- Contrast: one dark piece and one light, as with the black and tan sofas above.
We work only with genuine leather: 76 colours in 12 colour families, with Italian leathers as our top leather group. Fabric upholstery is also possible, and we accept customer's own material (COM). Colours look different on screen, so ask for leather samples before you decide.
Frequently asked questions
Which sofa set models are in style for 2027?
Sets built around one main sofa with two armchairs, curved or rounded sofas, long and low sofas, and Chesterfields combined with modern pieces. Warm, muted leathers such as brown, ochre and muted green suit all of these formats.
Is a 3+2+1 sofa set still in style?
Yes. It is still the most practical choice for family rooms that need many sofa seats. For 2027 it looks fresher when the armchair is a different model or in a contrasting leather.
Can you mix a Chesterfield with a modern sofa?
Yes. Let the Chesterfield lead, keep the modern sofa plain, and repeat one link between them, such as a leather tone or the finish of the side tables.
Sitdesign has been making furniture since 1983, and every piece is handmade in our own factory in Büyükçekmece, Istanbul; upholstered pieces take 3–4 weeks.
