Somewhat of an oxymoron - speaker stands for the floor for bookshelf speakers.

Some speakers will have available factory stands as well. My Focal bookshelf speakers had threads in the bottom to allow them to be attached to the stands, making them a single solid unit. The height of the stands was perfectly designed to get the speakers properly aligned to the listening space. The Blue Tack mentioned elsewhere is also a good solution.

And how does the speaker stay on the stand without fear of knocking the speaker off  - if accidently bumped? 

Velcro!

Blue Tack!

Works great, leaves no marks!

I could never understand why some people think bookshelves on stands look any better than floorstanders. When you come right down to it, what's really the difference?

It's not always about looks. In some instances a monitor will be a better fit for a given room. And subs are easier to dial in when placed in a small(er) room than trying to position a full range speaker to achieve the same flat bass response.
