How do you make sure the plant weight doesn't tip over the bench?

First association: a plant growing out of a toilet.

Not digging it.

Nice palm--I've seen several variations (some from Japan) of the same idea but with a bench.

I would be worried about someone sitting or putting weight on the plant end.

Other sources: I saw a photo from the 60's where a potted plant grew through the slats of the Nelson bench. I believe Room and Board had a square coffee table that accomodated a plant in the center.

Great... so now it's even more convenient for kitty to use it as a litter box.

You're really concerned it will tip?
