Most sofas fall into one of four characters: the classic chesterfield, the modern low sofa, the soft lounge sofa and the compact sofa. Each one changes how a room looks and, just as much, how people sit in it. Choosing the right character first makes every later decision easier, from the seat depth to the leather colour.
This guide describes each type with typical measurements, the rooms it suits and the kind of owner who tends to enjoy it. You can compare the examples below with the full range in our sofa collection.
Start with the room
Before you look at styles, measure three things: the wall or zone the sofa will stand in, the walking routes around it and the ceiling height.
- Length: a common rule is that a sofa should take up roughly two-thirds of the wall behind it. On a 4.5 m wall, that points to a sofa of about 3 m.
- Clearance: leave about 40–45 cm between the sofa and the coffee table, and around 90 cm for main walking routes.
- Height: in rooms with ceilings under about 2.7 m, a lower back keeps the room feeling open; high ceilings can take a taller, more upright sofa.
With these figures written down, you can rule out models that will not fit before comparing looks.
The classic chesterfield
A chesterfield is recognisable by its button-tufted upholstery and rolled arms that usually sit at the same height as the back. The seat tends to be firmer and more upright, with a typical seat height of 44–47 cm and a seat depth of 52–58 cm. That posture suits conversation more than lying down.
It works well in formal living rooms, studies, offices and rooms with generous ceiling height, where its strong outline has space around it. It suits owners who like a structured seat and a traditional room. In genuine leather, a chesterfield develops a deeper colour and a softer surface with daily use. Our chesterfield sofas, such as the Edward sofa, show how the same idea can vary in arm shape and length.
The modern low sofa
A modern low sofa has a back height of about 70–80 cm, a seat height around 40–43 cm, slim or block arms and clean, straight lines. Because it sits low, it keeps views to windows and artwork open, which is why it is often chosen for open-plan living areas.
The lower seat feels relaxed but takes more effort to get out of, so it suits younger households or rooms used mainly for lounging. For cleaner lines, look at models such as the Nova sofa, and check the seat height on the product page against the people who will use it most.
The soft lounge sofa
A lounge sofa is about sinking in. Seat depths of 65–75 cm, loose back cushions and rounded or curved forms invite people to tuck their legs up or lie across the seat. It is the natural choice for a family room or a television room.
Two things to plan for. First, loose cushions need regular plumping to keep their shape. Second, a curved sofa needs space to stand free in the room rather than against a wall; allow at least 1 m of open floor behind or beside it. The Janette Curved sofa is an example of this softer, rounded character.
The compact sofa
In an apartment, a study or a bedroom, a two-seater of about 150–180 cm is often the right size. Choose slim arms of around 10–15 cm so that the seat keeps most of the width, and raised legs that show the floor underneath, which makes the piece look lighter.
If a room has a free corner, a corner sectional often seats more people than two separate sofas in the same floor area. The Happy corner sectional sofa is one example; measure both walls and the opening to the room before ordering.
Matching the sofa to the people who use it
The same style can feel very different depending on who sits in it. A few practical checks:
- Tall users: look for a seat depth of 58 cm or more and a back that supports the shoulders.
- Older users: a seat height of 45 cm or more and firm arms make standing up easier.
- Children and pets: genuine leather wipes clean easily; darker or mid-tone colours hide daily wear better than very light ones.
At Sitdesign every piece is handmade in our own factory in Büyükçekmece, Istanbul, on kiln-dried beech frames with high-resilience (HR) foam and sprung seating. We use genuine leather only, in 76 colours across 12 colour families, with Italian leathers forming our top leather group. Fabric upholstery is also possible, and we accept customer's own material (COM). Custom dimensions are available on request, and upholstered pieces are typically ready in 3–4 weeks.
Next step
Write down your room measurements, choose the character that matches how you live, then narrow the colour. If you would like leather samples or a quote for a specific model, contact us with your measurements and we will help you compare the options.
