My beautiful wife got me this awesome chair from EQ3 known as the CHAPMAN Office Chair. Its both stylish and comfortable. Link to it here.
Originally, I was going to get the West Elm swivel leather desk chair, but that turned out to be too stiff and not all that comfortable. Luckily, the EQ3 store was next door and this chair was only marginally more expensive, but much more stylish and pleasant to sit in.
