Here’s some assistance on Leather Terminology
Leather is processed skin or hide that has been put through a tanning process which turns it into a non perishable material which can be legally called leather. Almost all upholstery leather is chrome tanned which involves rotating the skin or hide in a drum containing a bath or chrome liquor. The result is called “Wet Blue” leather which then requires significant further processing before it can be used in Upholstery.
If you don’t quite get the difference between Pigmented and Coated Leathers, here is some help. The surface of Pigmented Leather is coated, that is coloured, with a material containing pigment and is in effect, painted. The colouring is opaque and may be sealed with a polyurethane coat or laquer. This leather doesn’t absorb water readily and so is quite easy to wipe clean. But unless this leather is cared for properly it can crack and deteriorate. So there’s no real difference in the terms Pigmented or Coated, essentially they are interchangeable.
Watch out for the use of the term Finished Leather or Fully Finished Leather as this encompasses all the procedures that can be applied after the initial tanning and dyeing process and includes, rolling, spraying, waxing, milling, buffing, embossing, antiquing plus coating and pigmenting. It’s a nice term that is often thrown around but needs to be qualified!
