Sack 'n Seat

Though I can't read or understand anything on this site, it's pretty clear how the Sack 'n Seat works. Just pull out the fabric from the handy travel pouch, loop the fabric around the chair back and secure the buckles, place the baby in...and just like that, you can turn any chair into a safe, secure seat for your baby. Sure, it doesn't boost the baby to a comfortable height for eating at a table, but it seems handy in a pinch when you don't want to lug a bulky booster seat around. I love how portable the Sack 'n Seat is and it's a simple concept, really - it takes the sling idea and adapts it for use on a chair.

I found a site where you can get it for $16.95 at The Baby Hammock.
