"Relaxing" on my island?

[Kirika-]

Once you get flying on your island, fly into the hanging chair from the outside of your house.
This will force-dismount you (the house is a Hoofing-It zone), but you will be inside of the cavity of the hanging chair.
Trying to jump into the inside of the chair, I couldn't do it originally, but flying into it did work. Jumping does seem to work as of today.
Then type /groundsit, this will cause you to /sit but ignoring the static sit-spot of the edge of the chair.
You will then be sitting inside of the chair's cavity on top of the cushions.
You can then use /cpose to cycle through your different sitting positions.
