The $199 IKEA Markus is a high-backed chair that comes in a variety of colors and your choice of leather or padded fabric, with a mesh back for breathability. Compared to some of the others here, the Markus is lacking in features and customizability, but if you sit in one for a while, you'll find it remarkably comfortable (I was thinking about getting one myself before I got my Embody.) It is height adjustable and can tilt and lock, but don't expect to independently adjust the armrest width or height, or change the seat depth. The curved design and the mesh back to support your back, however, and the seat pan isn't really deep enough for you to slouch or sit improperly, so it does enforce good posture. If you're on a budget but want a quality desk chair, it's a great bang-for-your-buck office chair.
