Aniline leather is leather that has been dyed in a bath using aniline dye. The resulting leather is open-pored and smooth without pigmentation (coloured coating), or at most a light coating on the surface, which preserves the natural appearance of the hide and is generally considered to be very expensive and valuable. Thanks to the lack of pigmentation, aniline leather retains a soft, warm touch and transparent appearance with all of the natural features of the hide, such as variations in colour and texture, liver spots, tick bites, scars, hedge scratches, skin folds and grazes etc. In this leather category, it is acceptable to process closed, incorporated natural features, thus each piece of furniture is unique and will deviate in colour and structure from the sample! Aniline leather tends to fade and develop “speckles” (patina) with use.
