ZOMG I made this product for other developers because the room we derive furniture from is so ugly. Maybe you've seen it on some product pages. Anyway, you can buy this room if you want to for pictures and stuff. I don't mind if you use it in the previewer though without buying it XD Here's how:

ZOMG ugly room XD

Make sure you have your previewer in advanced mode.

Click on the "Scene Manager" tab and put the product ID number for this product, 1237276 in the box as shown.
Then click the huge "Apply Changes" box. ZOMG no more ugly room XD.

Happy developing!
