I had these and loved them! I would take the babies out after wiping them down in the seats, dusting off any food. Then wipe down the highchairs, pick them up, shake them into the mat as well, fold the mat in half and walk it over to the sink to dump.

A little warm water and cleaning them was easy with these and they are really soft so they weren't harsh on their skin or face.
When the boys were first starting to eat solids we used the Bumble seats with the tray on the splat mats on the floor. This was great because being low to the ground made less of a mess. The Bumble seats are hard to clean though and you aren't supposed to submerge the tray in water, only wipe it off.
