Google search product name

So for every product that is indexed in google search, at least the ones I have checked, the name appears to be strange.

As in an image, number 1. Is the title page, but number 2. is another product, not related to the first one kind off. And part 2. is always the same for every search result.

Lets say for example it appears in search like this: 1. Big Kitchen Table - 2. Yellow Chair... Yellow chair is a product too, and its always next to the name of the product that is found in a search.

Where does google take part 2 from?

Hope that makes sense...
