I think I should get a 2 seater for part one. And a 3 seater for part 2. However I measured that my sofa length is slightly bigger than your suggested length for the 3 seater? Example your seater states 190cm -230cm. But my question is can it's actually stretch beyond 230cm? If can I will get it. Not considering 4 seater because many reviews says the cover are bigger, I don't want to end up having alot of excess, I'm very particular about how neat it will look after putting it up. My sofa is almost new not spoil, theres nothing that I wish to hide underneath the covers, just want a protection. So if it wont look nicer, and have too much excess, then I would prefer orginal.
