Hi @Seanwrc, welcome to the Sonos Community!
From what I can see online, it doesn’t look like Ikea sell the stand separately and I can’t find any information on my end that says they do. Ikea might have something that works with the Symfonisk Lamp, so I’d recommend reaching out to them directly to see their options.
My reply will push this thread to the top of recently active and may bring in other users who have some suggestions for floor stands you can use with the Symfonisk Lamp.
When they switched to Gen2, with the bamboo and glass shades, they were sold as the lamp with no shade as well as different lamp+shade packages and the shades separately. In the UK they list all 3 shades as separate items that can be bought.

I don’t think I’ve ever seen the stand from the floor lamp version available on its own. It screws into the bottom of the speaker, so the floor standing version might have a different base on the speaker to the lamp versions.
Ikea customer support/spares would probably know.
As an alternative to the stand included in the Floor Lamp Symfonisk, any stand/shelf unit of the height and design you desire with a large enough top shelf would work as a stand. Whether something is sold as a plant stand, speaker stand, narrow ladder shelf or whatever doesn’t matter if you like the design, the lamp you have fits on top and it supports the weight.
