Where 's a good place to buy second hand furniture (Bangkok)

HI guys, I just moved here a month ago and am still setting up my pad. I dont want to purchase brand new furniture coz its a rented place. But basically I'm looking at IKEA style stuff, or even old comfy armchairs/sofas. So is there a place I could go to to buy second hand/quirky/hipster furniture/household stuff?

Many thanks in advance.

Also if anyone is selling their stuff, do contact me as well!

cheers,

hari
