hi everyone, does some one know that where i can buy cheap furniture in Lausanne?

Go to Emmaus in Etagnieres.
Last time I was there they had loads of very cheap furniture and all kinds of kitchen equipment.
Some of the stuff is absolute rubbish, but every so often there's a 'jewel'.
Just Google Emmaus Etagnieres for a map.
It's on the road to Yverdon.
Good luck.
