Beyond Looks: Function, Comfort, Upkeep and Consistency

A room is usually judged in the first ten seconds: colour, light, the shape of the sofa. The way it is actually lived in shows up later, in the third month, when the same seat is used every evening, the same drawer is opened every morning and the first glass of water has been set down on a table without a coaster.

Yacht interiors make this especially clear. In a saloon like the one in our AL REEM project, space is tight, sunlight is strong and every seat is used, so a piece that only looks good is noticed quickly. The same four questions apply to any home or office: does it function, is it comfortable, can it be maintained, and does it hold together as one room?

Function: start from what happens in the room

Before choosing a single piece, write down what the room is for on an ordinary day. A living room might need to seat five for a film, hold a laptop on weekday evenings and store board games, cables and remote controls. Each of those uses translates into a dimension or a choice.

• Walkways: a common rule is 75–90 cm for main routes and at least 45 cm between a sofa and a coffee table.
• Reach: every seat should have a surface within about 50–60 cm, whether that is a coffee table, a side table or a wide arm.
• Storage close to use: things kept where they are used are put away; things kept in another room tend to stay out. A sideboard such as the Lavor sideboard next to the dining table keeps cutlery, linen and glasses within two steps.

If a layout looks right on paper but forces people to walk around the coffee table to reach the door, it will feel awkward every single day.

Comfort: something you can measure and test

Comfort is often described as a feeling, but most of it comes down to a few numbers and the way a seat is built. For upholstered seating, these ranges are a useful starting point:

• Seat height: typically 42–46 cm; lower seats feel more relaxed but are harder to get out of.
• Seat depth: around 55–60 cm for upright sitting, 60–70 cm for a lounging sofa where people tuck their legs up.
• Arm height: roughly 18–25 cm above the seat, so the forearm rests without the shoulder lifting.

Construction decides how those numbers feel after a year. At Sitdesign, upholstered frames are made of kiln-dried beech and seats combine high-resilience (HR) foam with sprung seating, so the cushion recovers its shape instead of settling into a hollow. When you try a model from our sofa collection, such as the Nova sofa, sit for ten minutes rather than ten seconds: check where your knees fall, whether your lower back is supported and how easily you stand up. If one dimension is not right for your household, custom dimensions are available on request.

Maintenance: how the room will look in month twelve

A material that suits the room in the showroom may be the wrong one for a house with children, pets or a south-facing window. Choose materials for the way the space will be used, not only for their colour.

• Leather: pigmented and semi-aniline leathers resist spills and light better; aniline leathers feel softer but mark and fade more readily. Our leather page explains the groups; we use genuine leather only, in 76 colours across 12 colour families.
• Fabric: tighter weaves and mid-tone colours hide everyday wear better than very pale or loosely woven fabrics.
• Tops and surfaces: marble needs coasters and regular sealing; lacquered or oiled wood needs a cloth, not a wet sponge.

Plan the routine before you buy: a five-minute weekly wipe and an occasional leather conditioner are realistic in most homes, and our guide to leather sofa care and cleaning covers the details.

Consistency: one set of decisions across the room

Rooms that feel calm usually repeat a small number of decisions rather than adding new ones with each piece. This is less about matching and more about keeping a clear logic.

• Limit finishes to three or four: for example one leather, one wood tone, one stone and one metal.
• Repeat the same leg finish or base detail on the sofa, armchairs and tables.
• Keep heights related: coffee tables a few centimetres below seat height, side tables close to arm height.
• Choose one detailing language, such as piping or clean seams, and use it throughout.

Consistency also helps later. When a piece is added in two years, a clear palette makes the choice simple.

A short test before you order

Before you commit to a layout or a set, run through these questions with the floor plan and your samples in front of you:

1. Can everyone reach a surface from their seat?
2. Is there a clear route from the door to the window and the kitchen?
3. Have you sat on the seat for several minutes, at the height and depth you are ordering?
4. Does the leather or fabric suit the light, the pets and the people in the room?
5. Do the finishes repeat, or does every piece introduce something new?

If you would like to test these points on your own plan, contact us for leather samples and a quote. Every piece is handmade in our own factory in Büyükçekmece, Istanbul, and upholstered pieces are typically ready in 3–4 weeks.
