My husband drives a semi truck over 700 miles a day. We saw this in a local truck stop, but waited to buy it on Amazon for his birthday. Overall he likes it, after using it for almost a month. He does say that he has to preposition it throughout the day and that he wishes it were wider. He's definitely not an overweight guy, most would consider him on the thinner side of average, so I gave it 4 stars for the width. It's also pretty pricey, but that seems to be the price wherever you look. But, if they're charging that much for a seat cushion, it should be wide enough for the normal driver.
Rating: 4 stars
