Ian,
The reason I asked the question is that you will not always have the luxury of asking others before proceeding.
The fibre mix indicates that the suite should be wet cleanable, so what else do you need to know?
You say you did a colour test. I'll assume that you tested for crocking, dye transfer and bleed, plus colour change with all the product you intend to apply
Another useful piece of information is whether the fabric will physically alter in other ways if made wet. Will it shrink or stretch? Is there something in the construction of the fabric that will de-laminate, for example.
Most upholstery will allow inspection of the back of the fabric for anything suspicious and you should know how to test for shrinkage/sagging.
If the fabric passes all these tests then it leaves you to decide on the matter of temperature, which comes from knowledge of the fibre characteristics.
