Hi again

I'm trying to make the bottom of a bar stool, I've included a picture for reference.
I'm trying to understand how to make the legs. I've tried using a polygon primitive cylinder then selecting all the faces at the end and extruding them out using the extrude tool with it following a CV curve. This method only seems to work with one face selected at the end not all of them. I know I need to use the taper and twist but I'm missing part of the method in the middle. Or I'm going about it completely the wrong way. Basically I want to know how to bend a cylinder shaped primitive to my required shape.

Cheers
