Some searching in the 3D Warehous may yield what you need, or at least something close.
For me, the room layout is the most important, the furniture is more a general illustration. Therefore I prefer quite simple models (small file sizes) that will not distract my work. But I also need furniture to have surfaces that can be changed and textured to see the general overall impression. I posted some chairs I could not find in the catalogue - small file sizes that can be textured and scaled to do the trick for me.
But well, it depends on how accurate you want your recreation. See SH3D Sourceforge 3D models 288.
PS. Sometimes I make exact replicas of existing furniture, but that is only when they are so off that nobody is likely to have made them - or need them ...
