A bucket chair is the only one I would want to sit to watch a movie, without feeling left out, don't think it would be too hard too move around, you can get the swivel bucket seats also

Hi nhuneke :) A classic dilemma for all except those who have space to spare... :-/ ;-)
You would need a chair that is as adjustable as possible, to fit all the uses. I would probably go for a good, high quality office chair. They come in all styles, all shapes and sizes, so I'm absolutely sure would be able to find something that has the right look for you. Also, they're height-adjustable (lower them a bit for the relaxed sitting), the back is adjustable (lean back to watch that movie ;) ), and they have wheels, so that makes moving it between rooms a lot more comfortable. Just have an image google for office chairs, you might get bright new ideas. And look for one that has removable armrests - or at least, armrests that can be lowered - for the dinner table use. And if you find one that looks too "office-y", but is otherwise what you need - that's nothing that a good upholsterer can't fix, by adding a nice, removable (and washable!) cover in the style you like. :) Good luck!
