Query: Excellent booster!

I was a bit hesitant to buy this booster, although it came highly recommended. I felt like it was overpriced and essentially offered nothing...boy, was I wrong! I've been using this booster for 2 years now. It has been used by my 3.5 year old and his 2 year old brother. Both of them LOVE it. The seat is comfortable for them to sit on, unlike the hard plastic seat we had before it. It doesn't slide around on the chair, and it is SO easy to clean. I also like that it is easy to take along if we're headed to grandma's house. No extra straps, trays, or pieces to worry about! I don't have a single complaint with this seat after 2 years of use...it is well worth the money!
