How do you keep your dog off the couch?

I adopted Brenya from a rescue who believed that as long as there are plenty of dog beds provided that your newly adopted grey would do well knowing it is not allowed on couches/beds to prevent any issues. I have always let my dogs on the couches and bed, but my fiance is really not fond of the idea of dogs on the furniture. We do not live together yet, but when we get married, I can forsee an issue with us aruging if the dogs should be allowed on the bed/couch or not. Since I do have a dog bed for pretty much every room, and I am already dealing with some growly issues from Seven when he is on furniture and I ask him to move, I think I am going to try and keep both pups off the furniture and on their dog beds. I just want to know how to go about doing this! Both dogs will come up to the couch and try to get on, where I redirect them to their dog beds. They sometimes stay put on their bed for an hour if they are busy chewing on a marrow bone, or it can be literally 2 minutes and they are back trying to get back on the couch again, where I just keep telling them "no" and bringing them back to their dog beds! Any tips on how to keep these spoiled bedhogs on their own beds? []
