Done right, it looks great!

I love the pillow idea, but I also think there needs to be a cloth down in front so clothes and legs don't get scratched by the bales.
Here is some cloth down in front, and lovely arrangements at the sides.
Cute bale sofa or luv seat - photo from HERE
This looks like it is to be used as a sofa table. The tray on top of the bale would keep the glasses upright. That comes from Green Wedding Shoes
Assorted quilts covering the bales - from West Aussie Wedding HERE!
Bales can even be used as a table or tier display. There are small bales sold in stores for table top decor.
There are more pics HERE
And of course, check out Pinterest for bale seating.
