In my humble opinion, that is never going to happen. I hope you didn't pay much for it, and learned a lesson. Now, if you don't get it out of your house as soon as possible, other things in your home will acquire that noxious smoke smell, like nearby upholstered pieces, and carpeting.

Don't throw any money away on cleaners, etc. The smoke will have penetrated every fiber of that sofa, every cushion, and probably on into the frame. To the dump it goes!

The smell will never go away regardless of what you try to clean or mask the odor. The odor has penetrated too deep into fabric and wood. Give it to charity and someone that smokes will enjoy using it and will add more smoke odor to it.
