Has anyone ever used car seat tables and footrests? One Step Ahead sells this combo unit as well as the table and footrest separately.

I don't have a Toddler Bargains book to reference...do they rate/review them in the book?

My son is 3+ and I thought it would come in handy on long trips, but I'm concerned about the safety of it in the event of an accident.

Thanks.
