How to use GF for Conference table bookings

Hi, I’m new on this forum and somewhat to GF. I’ve been using GF for sometime but only for minor forms ect.

I want to use GF to allow users to book TABLE SETTINGS/Chairs for a Conference.

I don’t know if there is a 3rd party add-on that can do the job or if GF is not adequate at all for this job.

This is an example of what I’m wanting to accomplish -

If there is a better way, please tell me.

Thank you much for any assistance.
