Advice is academic ' after the event ' however,
Cotton is usually flimsier than other fabrics
Cotton is a loose weave
Cotton suites usually have machine washable covers
Avoid cotton suites, unless you have a moisture control, upholstery tool.
Opinions are easily given, but without actually seeing the suite, it's not likely that anyones opinion will be really helpful.
From personal experience, I had similar problem, many years ago, with a cotton print. They were a nightmare and scared many cleaners, as they were liable to suffer from, colour migration, shrinkage, or splitting.
Most of these are long gone, but there will still be a few around, so beware.
Tme main problem, is the, loose weave and delicate nature of cotton, compared with other fabrics.
If too much water is applied, the foam padding expands and the cotton, being a loose weave can burst.
Abrasive action from, tools, hoses, plastic and metal fixings, which other fabrics cope with, can easily burst cotton.
