Free sculpting plugins ?

[SamatVogue]

Ive been trying to create soft shapes like chairs and cushions etc.

Until recently Ive been using Vertex tools to achieve this as all the tutorials online use it alongside subdivide and other thom thom pluggins.
Since I downloaded it a 30 day trial has been put on the pluggin and I am unable to now use it.

My boss doesn't want me to use any paid extensions, are there any simalar to Thom Thoms vertex tools, or any other 3d modeling tools you can recommend?
I am also unable to use the Artisan pluggin that everyone is using for the same reason.
