Looking After Leather And Upholstery

Sofas and chairs usually fail before their frames do. The covering degrades in ways that are gradual, predictable and largely avoidable with a small amount of routine attention.

Leather is a material that dries out

Leather is a protein structure held supple by fats and moisture distributed through the hide during tanning. Those components migrate and evaporate over time.

As they leave, the fibres stiffen and lose the ability to flex without damage, which is why cracking appears first on the seat cushions where bending is greatest.

Heat accelerates it sharply. A leather chair beside a radiator or in direct sun will stiffen years earlier than the same chair in a cool corner.

Finishes decide what leather needs

Most furniture leather is pigmented, meaning it carries a coloured surface coat. Cleaning acts on that coat rather than on the hide, and conditioners work through it slowly.

Aniline and semi-aniline leathers have little or no surface coating. They feel better, absorb spills immediately and mark from water alone, which makes them far less forgiving.

Applying a product intended for one type to the other is a common cause of patchy darkening, which is why a hidden test area is always worth the delay.

Fabric wears by abrasion

Woven upholstery fails where it is rubbed: the front edge of the seat, the arm tops and the point where a head rests against the back.

Grit is the accelerant. Fine particles work into the weave and cut the fibres from within each time someone sits down, which is why regular vacuuming extends life more than any treatment.

Rotating and turning reversible cushions spreads that wear across more of the fabric, and it also evens out the compression of the filling.

Spills are a timing problem

A liquid on upholstery spreads outward and downward into the filling. What is visible on the surface is a fraction of what has actually been absorbed.

Blotting from the outside inward lifts liquid without driving it further out, while rubbing pushes it deeper and disturbs the pile so the mark shows even once dry.

Over-wetting during cleaning causes the classic ring, because dissolved soil travels to the edge of the damp area and deposits there as it dries.

Light and position

Sunlight fades dyes and weakens fibres, and it does so unevenly, so one arm of a sofa ages faster than the other in most rooms.

Moving furniture occasionally, or adjusting blinds during the brightest part of the day, keeps the fading uniform enough not to be noticed.

Where a piece is valuable or the covering is unusual, professional cleaning is the safer route, because the wrong solvent on an unknown fibre is not reversible.
