A minor victory for me today.
Convinced Jen to let me use her office chair for a while untill she actually starts using it.
To put into context, my current one is this essentially:

Note: this is her old chair, tis a piece of shit with a broken back. Using it is fucking uncomfortable.
She essentially has this:

However at present she NEVER uses it, she uses her laptop whilst sat on the sofa and this awesome chair gets used as a book rest. I've bugged her for ages to let me use it, as obviously she doesn't, but she's always insisted I cant.
Finally she caved today, and I am currently sat in this pile of win chair. Seriously so fucking comfortable right now
