Sonos doesn’t actually sell the lamp, it’s only sold through ikea.  Checking their site, I don’t see an option to buy just the shade, but perhaps you can get a replacement through their customer service?

Also, others have managed to get standard lamp shades on to this speaker.

Hi Julio,

Exactly the same thing happened with us. My 3 year old broke the lamp shade / dome. 

Did you manage to find a replacement?

Thanks

Hello Keith.

No, had to make some creative adaptations….

I did use the below, and some 3M reinforced double-tape.

Result is below, hope that this helps…..

 

Keith, 3M tape should be heavy duty, as below:

Many Thanks!

Thank you Julio,

I only just saw this  message 

Separate shades are being developed for Symfonisk. Due out next year. Not helpful now I realize, but FYI
