Question about Suncomfort by Glatz Varioflex

Doppler Granite Base Plate. CHF 459.
Here at Galaxus.
I bought an adapter but didn't use it. Just drilled out the holes of the Glatz umbrella a bit. It's held up well for the second year.

Yes, there is a mobile foot from Glatz itself. VERY expensive.
Alternatively, I bought a 140 kg foot from another company. This one came with an adapter. I only had to drill 2mm into the existing holes. Then it fits and was half the price.
