Hair-stuffed things feel pretty dense. It's a firm padding.

My grandma's old house was in an awful, awful area. She finally moved out, and the house was later firebombed. She left behind a beautiful claw-footed bathtub just like that.
I suggested to my dad, mostly joking, that we go snatch it back. His response:
"Umm...I dunno...There could be a cadaver in it by now, for all I know."

... Is that your foot?

That would make a mighty nice print.

Oh yeah...the calming colour thing.
Didn't 'they' instruct families back then to paint that same "apple green" colour in kitchens, in order to make housewives calmer and happier?
Later, they realized that it actually caused nervousness and anxiety--and was, in fact, the same (or similar) colour used in interrogation rooms in jails/prisons/police stations/whatever.

I don't know--hydrotherapy in itself, back in the 1800's, wasn't particularly pleasant all the time, either. Nevermind the flower stickers, being plunged into cold water as a cure for...whatever ails your legs...doesn't sound too helpful.
