I use it in the car when driving in traffic for hours. Not perfect but I am certainly better off than without it. Good, sturdy cushion – maintains firmnes, does not sink in with the sligtest press. Not too soft or hard. Nice and wide (side to side). I am 5′ 4" and I would have liked it to be a bit longer (top to bottom). The back of the cushion is flat. At first glance it appears too thin but it is actually ok. Good thickness at sides, would have liked it a bit thicker at middle of cushion to support small of back in a greater contour.
