Great seat!

We absolutely love this seat. The install is a breeze, my kids prefer it comfort wise over our old gracos. The extended rear facing limits are fantastic, our 4.5 year old is still comfortably rear facing in hers. Easy to assemble and wash. Very slim side to side and incredibly compact front to back.
