I have a
Targus Spin Pad case:

It works perfect for me. I can read most anywhere. The handle makes it easier to hold the iPad in bed or I can adjust the spinner however works best. Infinite horizontal and vertical adjustment for all 4 sides of the iPad. Fits perfect and adds very little weight. Works with Apply or other covers to protect the screen if you need it.
Amazon has it on sale for $37.00. You can also search Amazon for "iPad spin cover" and find other brands for a variety of prices.
