We have one of these sitting in the garage which we ordered when we bought our van. I think when you have child seats it's a pain the arse for a few reasons, mostly because it makes moving the chairs around a little harder, but with child seats it also doesn't really lift up high enough for the kids.

It was great to have a table to work on with my laptop that one time I used it when we here travelling, but it's spend almost the entirety of it's life in the garage in it's plastic bag.

I think if your seats are somewhat static and you're only moving adults with laptops/things to use at the table it would be great... like in a corporate van. For the rest of us not so much.
