Also the cost of maintenance sometimes is more than it would be to drive a car and stay in a hotel.
The swivel car seat neither decrease nor increase your level of safety while driving. Of course, if you get pain in your rear while driving, it may be a great alternative to sit on, instead of on the raw stock seat.
