Seems also very valuable for remodeling-- not just furniture. The most commonly remodeled rooms are kitchens and bathrooms.
The site is agonizingly slow. You are serving up 200k+ images scaled down in HTML. Seriously? Make it as fast as hot or not and you have a winner.
I'd also break it down by room. Kitchen, Living Room, Bedroom, etc.
Of course, as with many sites-- there's no build in marketing. How are you going to get visitors?
