Out at the Picton Cars and Coffee day, someone asked me about these lifts I'd seen mentioned on another forum.
The lifts are fitted flush in a floor when retracted, are two panelled (one each side) so you can do trans work etc.
To me, way more useful than a four poster lift.
So, I can't recall who asked, but heres the link......
