Here is a badly designed chair. Made primarily in Zbrush by using the given primitives only, e.g. the body of the chair was made by using the gear primitive and changing its variables.
A few other parts were made in 3Ds Max.

I was practicing with Zbrush and decided I haven't messed with the primitives enough. When I found that I could change a bunch of stuff while in their non-edited form. I started to experiment.
