Hmm. I'm glad I just found this post. I ordered one of their custom seats earlier this year. It took over two months for them to send the seat to me. Which they did explain on their website that their custom seats take a while because they have to wait for a donor seat to come in. I was happy with the seat they eventually sent me, so I sent them my stock seat at part of the deal. It was cheap, and I did experience a vast difference in comfort over the stock seat. (They say you can send it back if you don't like it, and you just pay the shipping.) But it worked out nicely, and I like the way it looked and felt.
Now that I read this, I'm sure I will not attempt to order from them again.
Keep moving, learning, loving, and living.
