I had seen this, and it looks like it would sense that it is being squeezed. Agreed?
Or would it be better to use an LDR?
Or is there a LilyPad Arduino that would work well?
Any idea what I should do to have my mac recognize/track how long it's being squeezed?
I'm wondering if there is something similar i could do but just for my one chair?

Not at all? Then an LDR is probably not a good choice. A proximity sensor may be better.Small hole in a discrete location? Then an LDR is a probably a good choice. They are simple, easy to work with, and cheap.
How is the chair constructed? Is there a way to attach a flex sensor?
Id go with something capacitive, then no holes, just slip it under the fabric and maybe increase sensitivity if its too far away, look on the playground for capacitive sensing
You don't actually connect ground to the setup, the ground is sensed thru the objectthe larger the sensor the more sensistive it can be, it may take some trial and error to find out exactly what works
