The likelihood of you being able to install those particular seats side by side is fairly high IF you are installing the Evenflo
RFing.
Forward Facing, it may be a tight fit. IF you are near a specialty baby store OR a babies r us, they usually have the
Regents in stock.
As for re-designing the seat, they sort of did that when they updated the installs back in June 2007. I haven't heard anything about a re-design, but I am going to double check.
The
Regent,
Recaro, and
Radian's all have to pass the same safety standards. There are pros and cons to all of the seats. I, personally, own 2
regents as they are the tallest, highest weight harnessing seats on the market--besides special needs seats.
Cons-
regent--the size, the tether anchor requirement from 50lbs and up,
FFing only
Recaro--the
Como is oddly shaped--the shoulder space is 9" and the butt area is 11". I got to play with one at a conference, and found the shape weird. While it DOES have true side impact protection, which is probably why it is shaped like that, there is a
Recaro spokesperson on this board that could further help you.
Radian--the 65 and the 80 are the same height. It has also been incompatiable with quite a few vehicles due to the low belt path for
FFing.
Pros-
regent-highest weight and height on the market--different covers (such as the Madison for your
dd--VERY plush!)
Recaro--True side impact protection, microfiber covers, VERY easy install with
LATCH RF or
FF, this is a
convertible seat that can
RF to 35lbs and
FF to 70lbs AND you can tether it in the
rear facing position.
Radian--it is the narrowest seat on the market...this is a
convertible seat that can be tethered in the
rear facing position
