I posted recently, as a FaceBook status, that the experience of grad school is made smoother by having a certificate in office techniques and technology (I haven't got one). Being able to type, manage paper files, and keep the IT stuff working smoothly is a boon to what amounts to maintaining a private research office.
The other important elements were a taste for reading(5 hours a day is a minimum), a good laptop(with good back up system so an HD crash doesn't eat your work) and an Eames Lounge chair, like the picture here. A classic of modern design, this lounge chair was designed by Charles and Ray Eames. Mine isn't as good a replica, because it doesn't have the cast aluminum feet of the image, but it has the comfort. I can read and type in comfort. Two hours last night were great, reading, sipping a beer and thinking about my work.
My copy was a kind gift, and needs reupholstering, but it is so comfortable. I have wanted one since I was eight years old. I saw a picture back then in a book on home decoration, and fell in love with it. It is one of the few times I have been so impressed with an object.
