2 Standard or Queen pillows will usually cover the width of a Queen bed, while on a King Bed you would typically want 3 Standard pillows or two King pillows. For Euro pillows we typically need 2 for a Queen bed or 3 for a King Bed.
As far as what type of fill to choose for your sleep pillow, we typically recommend high quality down filled pillows. For a pillow that will be used for support in bed, a down feather blend pillow will usually be best. These types of pillows are firmer and more supportive, but also heavier the larger the percentage of feathers in the blend.
