I have versions of the anATOMic seat that I sell that are at (or under) 2 lbs after finishing.
I list 3 lbs on my website to be conservative, but most come out of the mold at around 2-1/2 lbs, then with trimming, etc.. they get pretty light!

Atom's seats are pretty comfortable. I'm using one on my highracer. Although I haven't finished the seat, here some pics:

I just rounded off the corners with my friend's jig saw after I took the photos.
