I tried responding to your post regarding space saver chairs but TB is acting weird and won't let me reply. So I'll try it this way
We love our space saver, not only for the saving space factor but also b/c we found it way better and it seemed much comfier than the 4 regular highchairs we got to try out. It's also nice and very portable so you could easily take it with you. We saw a family bring it to a restaurant. It works really well!!
