Shout to Urbane Cyclist, there for me in a tough spot again. Somebody stole my seat post and saddle overnight and they had a replacement in stock, and they were able to install it all for me in the time it took to get non-dairy ice cream at Honey's.

Fun fact: if you have the Captain's Chair on a Tern GSD, and you're the right height, you can sit back on the cushion and peddle your bike and you only /look/ ridiculous, it feels fine!
