Checking Leather Quality on a Sofa: A Buyer's Checklist

On a leather sofa, the leather is most of what you see and everything you touch. Yet two sofas in the same colour can look almost identical in a photo and feel completely different after a year of use. The differences are in the grain, the finish, the hand feel and the way the hides are cut and sewn, and most of them can be checked in a few minutes in a showroom or with a sample on your table.

This checklist covers what to look at, what to ask, and which answers should make you pause. At Sitdesign we use genuine leather only, and the same checks are the ones we suggest when you browse our leather sofas.

1. Look at the grain

The grain is the outer surface of the hide, and it tells you how much of the original skin has been kept.

• Visible pores. Hold the leather under a side light, for example next to a window. Full-grain and lightly corrected leathers show fine, irregular pores. A perfectly even, repeating pattern usually means the surface has been sanded and embossed.
• Natural marks. Small healed scratches or slight variations in tone are a sign that the surface has not been heavily covered. They are normal, not a defect.
• The fold test. Pinch and fold a corner of a sample. Good upholstery leather forms fine wrinkles that relax when you let go. Coarse cracks or a surface that looks like it lifts from the leather point to a thick coating.

2. Know which finish you are looking at

Most upholstery leathers fall into three finish types. None is "better" in general; each suits a different room and way of living.

• Aniline. Dyed through with soluble dyes and little or no surface coating. It feels very soft and warm and shows the full grain, but it absorbs stains and fades in strong sun. Our in-depth article on aniline leather explains it in more detail.
• Semi-aniline. Aniline-dyed with a thin protective layer. It keeps much of the natural look and softness and handles daily use more calmly. For many living rooms it is the practical middle ground.
• Pigmented (protected). A coloured coating on the surface gives an even colour and good resistance to spills and light. It feels firmer and cooler, and the grain is less visible.

A simple test with a sample: put one drop of water on it. On aniline leather the drop sinks in and leaves a darker spot for a while; on pigmented leather it stays on top. If you have small children, pets or a sunny south-facing room, a semi-aniline or pigmented finish is usually the calmer choice. In a quiet study, aniline can be a pleasure.

3. Feel, thickness and smell

Run your palm across the seat and the arm and pay attention to three things.

• Temperature. Genuine leather warms up quickly under your hand. A surface that stays cold and slightly slippery usually has a heavy coating, or is not leather at all.
• Body. Upholstery leather is typically around 1.0–1.4 mm thick. It should feel supple, not papery, and recover its shape when pressed.
• Smell. Genuine leather has a mild, natural smell. A strong chemical or plastic smell is a warning sign.

If you can see the back of a sample, look there too. Genuine leather has a fibrous, suede-like reverse side. A woven or knitted textile backing means a leather-look material, which we do not use.

4. Check the edges, seams and panels

Much of the quality of a leather sofa shows in how the hides were cut and sewn.

• Even stitching. Stitches should be the same length, run in a straight line and sit at an even distance from the edge.
• Matching panels. Every hide varies slightly in shade. On a well-made sofa the panels next to each other, for example the seat cushions and the arm fronts, are chosen to match.
• Clean edges and corners. Piping should be smooth and straight; corners should be neatly folded, without bunching or glue marks.
• Tension. Leather on the seat and back should be smooth but not stretched tight. Deep creases when nobody is sitting on it suggest poorly fitted covers.

When you look at a model such as the Platon sofa in leather, the seams along the arms and the seat front are a good place to start. Our IIFF 2024 fair page shows several of our leather pieces up close.

5. Ask the right questions before ordering

A sofa is more than its cover, so ask about what is underneath as well. At Sitdesign every piece is handmade in our own factory in Büyükçekmece, Istanbul, on frames of kiln-dried beech with high-resilience (HR) foam and sprung seating. Good leather only shows its quality on a frame and seat that keep their shape.

Questions worth asking any maker:

1. Is this genuine leather throughout, including the sides and back?
2. Which finish is it: aniline, semi-aniline or pigmented?
3. Which leather group is it in, and where do the hides come from?
4. Can I have a sample to see in my own room and daylight?

Our range covers 76 leather colours in 12 colour families, and Italian leathers form our top leather group. You can see an overview on our leather materials page. Colours shift between showroom lights, screens and daylight, so looking at a sample at home, next to your floor and curtains, saves surprises. Fabric upholstery is also possible, and we accept customer's own material (COM).

Next step

If you are comparing leathers for a sofa or a full seating group, we can send leather samples on request and prepare a quote for the model and size you have in mind. Custom dimensions are available on request. Contact us with your room size and preferred colours, and we will take it from there.
