Before you protect a new sofa

A new sofa is the easiest surface in the house to protect well, because nothing has happened to it yet. It is also the easiest to spend money on unnecessarily, for the same reason.

Six questions, in the order worth asking them.

Has the fabric already been treated?

Start here, because the answer sometimes ends the conversation.

A large share of contemporary upholstery — anything sold as performance fabric, most outdoor-rated fabric, and several house ranges — leaves the mill with a repellent finish already applied. It is frequently one of the reasons the fabric was specified in the first place.

If that finish is present and performing, a second treatment on top is at best redundant and at worst the cause of an uneven result. The useful step is to establish what is there, watch how it behaves for a while, and revisit later when it starts to fall off.

Ask the retailer directly: has this fabric been treated, with what, and is there documentation? A specific answer is a good sign. A vague one is worth testing.

What does the cleaning code say?

Every piece of upholstery carries a cleaning code, usually on a tag under the seat deck. It is a single letter and it governs everything that happens to the fabric afterwards.

Code	What it means
W	Water-based cleaners can be used
S	Solvent only — water will mark it
WS	Either water- or solvent-based cleaners
X	Vacuum and brush only; no liquid cleaning at all

An S or X code changes what is appropriate to apply and how the piece must be cared for afterwards. It is also the piece of information most likely to disappear, because tags get cut off or lost in the first year.

Photograph the label the day the sofa arrives. It takes ten seconds and it answers a question you will otherwise be guessing at in three years.

What is the fibre?

Not the colour, not the collection name. The fibre.

Linen, cotton, wool, viscose, polyester, olefin and the blends between them each take a coating differently. Viscose in particular is worth knowing about early, because it can mark from plain water whether or not anything has been applied to it — some so-called water rings on upholstery are the fibre reacting to moisture, not a stain.

The composition is usually on the same tag as the cleaning code, which is another reason to photograph it.

How will this piece actually be used?

Honestly, rather than aspirationally.

A sofa in a formal sitting room used at weekends is a different proposition from the one where two children eat breakfast in front of a screen every morning. Both are entirely reasonable. They lead to different recommendations, and the mismatch between the two is where most disappointment with upholstery comes from.

Worth stating out loud: whether anyone eats on it, whether pets get on it, whether it sits in direct afternoon sun, and who will actually be doing the cleaning.

What is the real first-year risk?

Not usually what people prepare for.

Spills are the anticipated threat, and a coating helps with them. But in a new sofa's first year the more common problems are dye transfer — new dark denim onto a pale seat cushion, which is a pigment migration rather than a spill and which no coating prevents — and delivery damage, which happens before you own the problem.

Inspect the piece at delivery, in daylight, before signing. Check the underside, the back and the seams. It is considerably easier to raise then than a week later.

And if the sofa is pale and the household wears new indigo denim, that is worth knowing before choosing the fabric rather than after.

Is a coating the right spend here?

Sometimes the answer is no, and it is fair to say so.

It is usually worth it on a pale sofa in a household with children or pets; on upholstered dining chairs, which meet food far more often than anyone plans for; on a bed headboard, which meets hair oil nightly and gets cleaned almost never; and on hospitality seating, where use is constant and replacement is expensive.

It is usually not worth it on loose covers that go in a washing machine, since laundering shortens the coating's life considerably; on fabric already carrying a good mill finish; on very dark fabrics where marking is far less visible anyway; and on a piece you already expect to replace within a few years.

The order that works

Take delivery and inspect the piece in daylight. Photograph the care label before anything happens to it. Live with the sofa for a week or two, so you can see how the room actually uses it. Then assess, patch test in an unseen area, and decide.

What we would bring to that conversation is the fibre, the existing finish, the patch-test result and a plain account of what a coating will and will not change. What you bring is how the piece is genuinely used.

If the answer is that the fabric is already protected and the sensible move is to wait, that is the answer you will get.
