It doesn't slice, dice or help prep dinner, but it does accommodate a larger number of people than we usually can.
Here is what our living/dining room usually looks like:
This setup is fine, except when we are more than eight people for Shabbos meals. Which is almost all the time, since we try to have guests for both dinner and lunch (we try to have a balance between people we are already friends with and new folks)
After a meal when we opened the table and put all the kids on the side near the sliding glass door and told them to crawl under the table if they wanted to get out ("not ideal" is really an understatement, although the kids were all 9 and under [i.e. so they thought it was really cool that they had permission to crawl under the table]), Penina came up with the genius idea to try to move the living room around. And it worked! Everything fits exactly when we move it around (i.e. we are very happy the living room club chair is not 2 inches wider, or it wouldn't fit).
First thing: the shtender (to stand and learn at) goes into the office, as does the ottoman.
Second step: all chairs to the side and club chair in interim mode. We can't move the table with the club chair in its usual spot (have I mentioned it's a bit of a tight squeeze here?!)
All done! Now we can fit ten to twelve seats for Shabbos! The club chair is to the side in what we refer to as "the reading nook" (during the week it holds Shalom Shachne's dining room chair that is now up against the sliding glass door). The nook is cozy and out of the direct line of the air conditioner (the largest sofa is right under the a/c and usually requires a blanket if one plans to sit there for more than a few minutes).
Now if I can only get the same expandable model in the kitchen ;)
