Sometimes wool can has a texture that can be irritating to some. To soften a wool couch we’d recommend using a soft fabric brush to soften the wool fibres. You could also use hair conditioner with light water – although we’d advise against this as it could discolour the fabric. A fabric steamer might also soften a wool couch, if used at a distance, but doing this may damage the fabric. And might cancel out any insurance policies you have.
