Go to Houzz Products. Scroll down to the Furniture. Click. Choose the category of furniture you want. Click. Enter search terms such as "gray" in the search box. Be sure to use quotations marks when entering search terms.

Make your own Ideabook for each category of furniture. Even if you are not sure about a photo, add it right then. It is impossible to find a specific Houzz photo unless you have the photo number. It is easy to delete a photo from an Ideabook.
