Is it possible and safe to attach this type of seat to suspension seatpost? I have a Merida Crossway 20 bike, and want to change its saddle.

Now after buying a new one I am not sure it is even possible to mount it. I had forgotten I have a suspension seatpost, but the new saddle seems to use a different type of attachment.

Is it even possible, and if it is, then is it reasonably safe to attach this type of saddle to a suspension seatpost?

The original seatpost + saddle:



The new one:
Looks like the new one has the same kind of saddle rails so you can remove the attachment from it and try the bare saddle rails in the suspension seatpost. It should work!

Undo the two big black nuts and it should all fall off. 

Edit (Grigory, Criggie): The extra bits are just the clamp from an older design of seat post. So they’re not needed, but might be useful back on the seat post they came from. The common interface on the saddles is/are the two parallel rails.
