FWIW, I've done in-home trials of several chairs. Many dealers of high-end chairs will let you do that (at least here in Poland). Sometimes I've had to leave a deposit.
I'm amazed how often a chair that feels great in the store turns out to be a complete dud once you place it in your workspace and sit on it for 2 days.
