K.W.
We have the Recaro seat. It's a forward facing one that converts to a booster and both me and my son love it. We were using a convertible one beforehand that was hard to adjust, he always seemed uncomfortable in and when I realized what I had to go through to get the covers off to wash it, I started looking for something different and decided on the Recaro. It's machine washable material is easy to remove and the straps and seat are easy to adjust. It's also very comfy soft material that my son has no problem snoozing in. the other thing I like about it is that the base isn't huge like many of the others so it fits nicely in the back seat while still leaving room for two other (smaller)passengers.
I actually have nothing bad to say about it--except the price, hehe. But after a year, I consider it well worth the money we spent on it.
