Cockpit Does anyone have a Hyperdrive cockpit and are they any good?

Have been looking at these online and like the colapseabilty of the unit. also the smaller seat which would allow it to be stowed away easier (keep the other half happy). Just not sure how stable they are.

This is the particular one I was looking at
