Clarification!
This dirty job is not done by me.
It is a first-timer production-manager somewhere in Chicago USA that does it.
I don't recall any mention about changing cushions or stuffing.
Anyway, I will email him to confirm.
It is very typical for absorbent leathers to expand three-dimensionally when it undergoes a full hydration and fatliquoring.
The leather structure swells, thus tightening up the obviously over-stretch leather that thins-out and spreads-out.
So, we are not just restoring for looks!
We are also restoring back the leather structure integrity.
The leather will regain its flexibility, strength and another lease of useful practical life - to be sat on with integrity!
This is a cut and paste from
TWheelwright explanation to Bruce!
It really is not very complicated.
Most things will contract as they dry out and increase (in thickness) in size when moisture is added.
That is why a 2"x4" of lumber is not exactly 2"x4" in size - those are the dimensions before curing and drying.
Over wetting a jute backed rug and the jute will swell in thickness causing it to shrink in its length.
Leather, when re-moisturized will swell in its thickness and tighten up in its length and breadth.
Look carefully at the creases in the back parts and seats in the first picture that have been caused by the leather stretching and growing in 3 dimensions and look at the same places in the "After" picture.
It is very obvious.
As you stretch an elastic band lengthwise it becomes thinner in thickness, same as with the leather drying out.
The foam cushion is unaffected by the work done on the leather and is unchanged.
The leather is thickened up by the addition of moisture and fat thus, fatliquor
