I have some gift cards to use up from Babies R Us and thinking ahead, I’m considering buying an easy to travel with booster for the car. Has anyone used the Mifold Grab and Go booster seat?

Based on reviews I’ve read it seems like it’s less comfortable than a regular booster but small enough to fit between two regular car seats.

My 4.5 year old is still in a harness, but thinking into the future for travel and car pooling, but curious about reviews!
