Simple, need new seat because the current one is ripped off and don't want to fix it with tape.What do you mean by seat and why do you want one? Do you only need a cover, or the whole seat? Is it because it's too high, too uncomfortable, or something else entirely? You can't expect other people to put too much effort into responding if you don't try to at least give a somewhat detailed account of the issue.
So you don't need a new seat. All you need is a cover. If you don't know how or don't want to do it yourself, take it to a car upholstery shop. It'll probably take 10 bucks of material and half an hour of labor.
