Item is a brand new maxi Cosi highback booster. Item was never used because it did not fit in my car (this is ideal for a car where the headrest can be removed). I missed the return window, which is the only reason I’m selling. Still have original box and packaging. Beautiful seat and very comfortable. Because of the brand new condition, I’m not willing to negotiate price. I originally bought for $200, so I’m asking for $150.
