 Padding: Light padding

The light upholstery can be recognized by its softness and suppleness. This is a padding that adapts to the body. The cover and the fine upholstery (Upholstery non-woven mat) are not consistently adhered to the interior, but hung loose and only connected to the outer sides. As a rule, new sets have either little or no waves. Using may cause conditional waves, which may differ from model to model or cover to cover. The undulations on the seat, backrest, armrests and clamping parts do not constitute a quality defect!

  • For ADA upholstered furniture
  • NAPPA leather
  • is exclusively used.

Nappa leather

The tanned hides are dyed deep in the barrel with an aniline stain.
As aniline colours are transparent, the natural surface (structural and growth characteristics) remains visible. This includes:

Aniline leather

For semi-aniline hides, only a small proportion of natural features are processed. To give a uniform colour to the surface of the skin, a thin pigment ink layer is applied to the pre-coloured skin. The soft feel and the natural appearance of the graining are fully maintained.
Features: easy-to-clean, durable fade-resistance, copes well at room temperature.

Pigmented leather

Pigmented leather uses the hides which do not meet the high demands of the semi-aniline leather range. Injuries and parasites may have led to open and unhealed scars, which are covered with a layer of pigment. Furthermore, leather is often ground to conceal the characteristics of the errors so an artificial grain pattern is then imprinted. Pigmented leathers have good performance features, are easy to clean, and have durable fade-resistance. However, they are less supple and breathable.
Features: easy-to-clean, durable fade-resistance
