Depends what furniture you want (well built ready made, flat pack takeway etc).
I think you will find Ikea interesting.
My wife and I have bought a few things from Ikea over the last 10 years or so and never had a "dud".
We have had an Ikea dining table for many years that is still in fine condition, some floor standing Ikea bookshelves in two alcoves that are still fine, and we also had our kitchen done out with Ikea units about 10 years ago and not had anything break yet (doors and drawers still work etc).
Even if you dont buy anything there Ikea is still woth a visit to get some ideas.
