I went to babiesRus website and found this...

If you can't open it I typed booster seat and it's by evenflo. These are basically the 2 I have (just newer models)...
Evenflo Chase DLX Booster Moonbeam
Evenflo Walnut Hill Chase Booster Car Seat
The top one I have for my 2 year old. And the other I have/had for my 6 and 8 year old girls. Had meaning my 8 year old decided this year it was too babyish. :) So I bought the regular booster seat for her.
I think these are great. They work for 20-100 lbs. You just use the harness until 40 lbs and then just a seatbelt with it the rest of the time.
I got the different model for my son thinking it would be a little cozier but overall I like my girls' better.
Hope this helps.
