Your posting said "models for Poser", so if you're willing to import 3DS models, this is the most amazing site I've seen in years.

There are literally thousands of pieces of furniture, beds, clothing, flowers, vases, light fixtures, etc. at this site. It's a little hard to follow as I think it's Russian. Don't click on the big 'DOWNLOAD" buttons. Click on the image once, it will be brought up by itself on the screen, then click on the image again. You'll get prompted for downloading. Some models are excellent; others seem to be only partially finished. I think they add new items daily. I'm at a loss as to how the site makes money.

As a safety precaution, I'd scan everything I download for viruses from anywhere on the net...

Good luck
