    The multiple cracks of various degrees appears on the stain area, which is the cause of the leather stiffness that result in cracks when further stress. More cracks will appears or existing cracks becoming worst if more pressure or flex is asserted to it.

    The stain that is the culprit of the problem has first to be eliminated or neutralized to its original pH value of 3 to 5, leather structure rejuvenated for suppleness and repairs with refinishing follows as an option.

    The strain is suspected to be of alkaline nature or reverting to alkalinity through natural fermenting process. It would be more precise if we could remember what this stain is otherwise the smell may give us the clue.

    Question!
    Is this area part of the armrest with years of accumulated sweat, oil and grease before I proceed with recommendation?

    Thanks ever so much for your response. Its a new chair or rather its a new chair to me (manufactured in the 70's). Thats correct its in the arm and would be the area someone would press on when the sit up therefore assume it pressure and sweat. Any thoughts on what i can do other than avoid putting pressure on the arms?

    Many thanks,

    Matthew

    Will need more pictures to help identify the finish or leather type before specific recommendation.

    From what we see so far, the leather is identified as “Aniline” with either a gloss or satin finish.

    This Aniline (A) Leather Problem Solving Guide is to be used as reference.

    The preventive measure is to soften and strengthen the leather without causing any ill effect to the appearance that may degrade its aesthetic. The procedure is recommended as follows:

    #1 Degreasing and Protonating:
    Product system to use - Degreaser-2.2 > Acidifier-2.0 > Hydrator-3.3
    This combination system will perform a deep degreasing removing contaminated soiling and protonating the leather protein fiber ionic positive (+ve) for pH leather chemistry integrity. Hydrator-3.3 help wicks or moves suspended soiling particulates to the surface by “reverse transfer” technique.

    #2 Leather Rejuvenating System:
    Product system to use – Hydrator-3.3 > Fatliquor-5.0
    The cracks is due to fatliquor dryness or diminishes, hydrating helps relax and plums the leather. With sufficient Fatliquor-5.0 thereafter will help reduce or close up the cracks to a degree.

    #3 Repair Topcoat damages:
    Product system to use AnilineTop-21G
    Most of body oil, grease and sweat prolong contamination deteriorates or damages the topcoat that after degreasing and erasing soiling particulates with Eraser-4, the pale grain leather reveals. AnilineTop-21G will magnify and amplify the color intensity of the leather to a degree depending on existing color loss or damaged.

    Tips:
    Any structural repairs with Impregnator-26 and or Bond-3D may take a darkening effect and the darkest shade will become the lightest color to camouflage them with “transparent” coating dyestuff that see through. All repairs to fill up the cracks can only be blocked off with Micro-54 pigment coloring, transforming the finish to a semi-aniline with an opaque appearance.

    Leather Doctor Kit A6.tc – Aniline Leather Topcoat Refinishing Kit
    Leather Doctor® Kit A6.tc, aniline leather topcoat refinishing kit is designed for topcoat repairs from friction wear, accidental scratch, scuff and abrasion to deteriorating greasy sweat stains. These topcoat damages are identified as white, dull or darkening stain from bare body contacts. Accidental whitish damages in most cases are free of soiling and direct AnilineTop-21G application with in between dry sanding rectifies most damages. Repairs to topcoat from daily wears that dulls will require a degreasing to remove penetrated rub-in soiling prior to topcoat application in a sequence process including Degreaser-2.2 follows with Rinse-3.0; Hydrator-3.3 follows with Fatliquor-5.0 prior to topcoat application. In a greasy and sweaty topcoat damaged areas especially to the headrest and armrest, a deep degreasing is essential follows with Acidifier-2.0 to stabilize the hydrogen bonding between the protein fibers with the other leather constituent like the tanning agent, dyestuff and fatliquor. This deep degreasing process is assisted by leather Eraser-4 in both the wet and dry cleaning process to remove soiling particulates off the leather surface. Hydrator-3.3 helps in the colloidal water movement bringing suspended soiling particulates to resurface through a dwelling and wicking process. Fat and oil is replenished by Fatliquor-5.0 in an emulsion form to penetrate into the leather structure. Once the fat and oil is hydrogen bond with the protein fiber, the water content breaks free leaving a breathing space for natural transpiration. The fat plumps the leather with fullness preventing the leather structure from collapsing during compressing and flexing while the oil lubricates the fiber from sliding smoothly over one another like millions of connecting hinges. Protector-B+ impart a non-stick, rub-resistant surface with a buttery feel helps reduce friction wear to the topcoat and extended a high level of appearance for a longer period of time. When the leather is contaminated with foreign soiling, it is essential to look at topcoat refinishing in a holistic approach. Note that the cleaning and rejuvenating products suffix denotes its pH value in this leather-safe aniline leathers topcoat refinishing system.
