Furniture can be somewhat more expensive but compared to the cost of shipping your menaje de casa along with almost certain damage, plus import costs and taxes, you'd be much better off buying furniture there, either new or especially used.
As I am browsing some prices, they do not seem to be expensive at all - a new 3-person sofa on sale for under $400 USD, a nice used ropero (wardrobe) for under $300 USD.
Plus the freedom of arriving with a minimum of baggage and being carefree cannot be overstated. Shipping a 20' or a 40' container and worrying about it, plus dealing with delays and the bureaucracy and inspections and taxes and port charges, the problem of unloading at the port and then transporting it to wherever at usually high cost, can give you big-time headaches that don't seem to ever end.
Here is a link for Locanto, like Craigslist where people can post without cost items for sale, etc., for Montevideo (other large cities also have Locanto):

Look under HOGAR Y JARDÍN on the left about halfway down, and then click on items starting with Muebles for furniture that people often individuals not businesses are selling. For instance this is the link for bedroom furniture, Muebles para dormitorios:
