My wife buys some that have a very small footprint and they are highly rated even though they cost so little that we didn't even debate abandoning one that one of the kids puked in while in Kalispell in July. She bought a replacement at Walmart, she said Target also sells it. They are about $45, wish I could help with the brand name.
We use German seats that cost a small fortune in our F-150 because we go on long trips in them and they are really comfortable, but in my wife's Cherokee and for travel we use these.
