I purchased this booster seat for my 14 month old son. He is learning to eat on his own and is very messy! Inevitably food falls onto the seat and gets trapped in the large gaps where the belts come through. Cleaning the booster is next to impossible because it does not disassemble, you can't even remove the belts. To clean it, I have to remove the fabric seat back and then spray the entire chair down in the sink! Even then, I am unsure if I have cleaned all the trapped food out because I can not see the area I am attempting to reach. I have resorted to covering up the gaps in the seat with masking tape to prevent frequent "deep" cleanings.The concept of the booster is great for people looking for an alternative to a highchair and who have younger children, NOT SELF-FEEDERS.
