Stevie,
Chemdry use water-based systems as their main cleaning methods, the same as the rest of us

The cleaning advice on suites varies between manufacturers, and a lot of them do word their cleaning instructions to deter customers from setting about them with a sponge and soapy water, or chucking the covers in the washing machine etc etc.
You need to use your common sense, instinct and experience as time goes on, to work out what's the best method and what the fabric can withstand.
The bottom line is that the vast majority of upholstery fabrics nowadays are perfectly fine for water-based cleaning.
BUT no matter how experienced you get you should always be cautious and test! I could have bought a suite on Saturday, I was convinced it was a polyester pile but turned out to be viscose. The only tell-tale was a little patch where the customer had used water on it. If I hadn't have spotted that I wouldn't have spent so long test-cleaning an area which then showed HWE to be a no-go!

You seem to have an axe or two to grind

Neither SM or CD can "brainwash" companies like M&S or G-Plan into thinking that only they can clean their upholstery. Give people some credit! The other thing you don't realise is that these companies hold service contracts with the franchises, who get sent out to troubleshoot problems like delivery damage/soiling, as well as a whole host of other report-based work. The care label is only part of the relationship between the two companies.
Being named on the care label of a suite is a paid-for privilege. The manufacturer gains from this too - by providing a trusted and respected company to go to for cleaning, it is an extension of their customer care. And also, dare I say it, many customers will benefit from the arrangement as well, because it will help them avoid either ruining it themselves or ending up with a cowboy instead of one of the many first-class independent cleaning pro's out there.
Interestingly, I'm a SM franchisee but I clean plenty of G-Plan furniture which recommends CD. I'm sure it's the same the other way round with M&S furniture. Funny things, people are
