IKEA - of course there is always better more expensive quality, but thier stuff generally lasts 2-4 years... alternatively you can shop for second hand stuff around town @ http://www.geoexpat.com/classifieds/, should start you up.
For more expensive variety, try Indigo in Princes Building, other wise, Ap Lai Chow, there's a mega ware house storage building, most nice places sell from there.
