An adaptor to fit a standard four bolt Unicycle saddle on to an old style bicycle seat pillar or plain 22mm diameter seatpost.
Bicycle seat pillars (without a built-in rail adaptor) come with a 22mm diameter seatpost section at the top as standard - the adaptor fits on to this section of the post. The lower section of the seat pillars are sized to fit the frame.
This seat adaptor is ideal for use on converting:

Pashley Unicycles with 25.6mm seatposts
Pashley Unicycles with 25.8mm seatposts
DM Unicycles with 25.0mm dia seatposts
Recommended for use will all unicycle saddles with standard 4 bolt fitting except the Nimbus Classic Saddle
