Works great

This is a big step up from the normal back support cushions out on the market. I love how this one is so much "taller" than the others. The memory foam is dense enough so it does not go flat but not so bulky it's akward. I did find that using it in my truck made it so I had to readjust my seat settings as it did seem to push me forward a bit. I go on long car rides both driving and riding and this will sure make both more comfortable. I would like to see them in lighter colors so they don't get hot sitting in the sun but I'm sure a little cover will work for that.
