Hey @Neven, welcome back!

I do not own any stands for my speakers, so it is a bit difficult to provide answers for you.

With my response here though, your thread got at the top of the latest activity list, maybe other users of our Community who own any of these stands can give you some feedback.

I hope this helps.

Thank you. Currently I have my Play 3’s wall mounted and plan to swap them for Sonos One SL on stands. I have real concern for Sonos, Sanus and Flexson stands. The only one that seems to securely hold the speaker is Soundbass stand which I hardly don’t see any reviews.

I have my Five on a stand, wasn’t happy with the security either so I used several 3M “Command Strips” in a larger size to secure the Five to the stand. They create a solid but easy to remove connection.

Very nice to know there is a solution. But still, i see a lot of folks recommending Flexson. I doubt there will be a problem, unless someone forces the speker of the stand. 

Thank you

Further I think about the possibility of speaker falling I begin to consider a wall mount or a shelf. It would not look as nice and won't be at ideal listening height but woul be a lot more secure.

Congratulations on your Sonos One SL pair! When it comes to stands, it's crucial to prioritize the security of your speakers. Many users find the Soundbass stands appealing due to cross their unique locking mechanism that ensures speaker stability. If you're concerned about the security of other stands, exploring options like Soundbass with positive reviews for stability could be a wise choice. Feel free to share your experiences or check online reviews to gather more insights from users who have used these stands for their Sonos speakers.
