Thanks for the nice words.
She woke up early and traveled for 16 hours, and when I turned this on she played for an hour until I made her stop and get some rest.
I guess you could say she loved it. She was standing up playing only for a few minutes, then got on her knees to play. So i told he she could use a regular chair, and that seemed to work out well.
I played it myself in a chair, and it's pretty comfortable.
I'll button this one up after a couple weeks to make sure everything is stable before I shell it, and then I'm off to some other projects.
