IKEA makes good beds - at least here in Japan. In US there tends to be a bottom box spring, then another spring "under mattress" whatever you call it - then the soft cushie thing you sleep on.
In Japan the IKEA sells these adjustable bamboo slat things as the bottom layer - buy the most expensive one - then the mattress - again the most expensive one. Most comfortable bed I have owned.
We bought loads of modular cupboards and shelving for the kitchen that is pretty good - its cheap, but "looks" nice - and actually the hinge hardware is great - nothing "slams" shut it slowly closes quietly.
Our couch is shit - agreed. Don't like it. We have a bookshelf that again looks sharp but is cheap.
I would stay away from - besides the bed - stuff you spend loads of time on - like the kitchen table, couch, kitchen chairs, etc. We paid a buttload for the kitchen stuff in the US and shipped it over. I actually had a guy from Extreme Home Makeover (well, he worked on the show as a contractor when the show came to MIchigan) shorten my table from and 8 person table to a 6 person table - it's solid teak - no f'ing way I was getting rid of it.
Anyway - cupboards, beds (if you buy the top of the line, and its the style described above that I got in Japan), bookshelves - no worries. As previously stated don't buy pots and pans. Dishes for everyday use and mates are FINE - but get yourself a few place settings for when you want to show you have some class that cost some money. We actually got lucky - you can go to (in the US, sorry never lived in Aus) to places like Bed Bath & Beyond and bought discounted really expensive place settings where the customer ordered 1 too many or whatever. We have 6 or so settings that are "similar enough" to look cool when we put them out - actually looks pretty cool - they don't all have to exactly match to be nice. Obviously we don't put out square and round and oval and a bunch of shapes - but all one general shape with generally compatible patterns is fine. Just check the stores every now and then and slowly build your eclectic fine china set! And save a butt;load of money.
For pots and pans - buy Calphalon with a lifetime warranty. Yes it will cost you more Cookware
but it takes a lot to ruin them, they last for years, and when one is damaged they send you a new one for free - of equal or greater value. It will be the last set of cookware you buy actually - because every few years you can architect a failure and get a new set. But even then - you won't need to - we have this set going on 4 years and we sent one piece back because I screwed it up. New pan arrive in days free of charge with a box to put my old one in.
Anyway - thats my 2 cents. Get a Roomba robot vacuum. Seriously good stuff if you have hardwood/short carpet. We manually vacuum once a month now that the Roomba is in charge.
