Purchased the yellow cover, which seemed a brave decision, but it is a lovely shade of pale yellow. The cover sizing was accurate and it was very easy to fit, which was lucky as my dog refused to sit on the sofa once the cover was on.
I swapped it to a slightly larger sofa, ( which the dog is not allowed on) and the fit was more snug, but very good. 
 The dog then decided he did like the cover after all and he is obviously very pleased with my purchase as it’s now his favourite place for a nap 
Good value, quick delivery, easy to fit.
