From Webkinz Insider Wiki
The Galaxy Theme was introduced to Webkinz World in February 2010.
When the Galaxy Theme was first introduced, members wondered about the chair-like item under the window in the theme preview. This item was not released with the rest of the furniture. A few weeks after the release of the theme, the Creative Director made the following announcement on Twitter @webkinz:
That was a "cockpit" chair that opened and closed. It didn't work right, so it wasn't released.
Shortly after that, the chair was removed from the theme preview.
