Wanted: Child seat

The only thing about the copilot is is doesn't have any give / suspension effect, unlike the ones that have two thick metal rails that clamp onto the seatpost. I always think these look a bit wobbly though.

My 2p.
We used the Hamax Smiley, basic version of the copilot.
The seat post clamping system looks a bit sketchy but does provide more comfort than a fixed (ahem) system.
