The Safeseat fits a larger child and is a slightly larger heavier seat. The Snugride is up to 22lbs (Wt w/o base: 7.5lbs/ Weight with base: 12.7lbs/ Dimensions: 24.2"H x 17.5"W x 26.7"D) The Safeseat is up to 30lbs (Wt w/o base: 9.8lbs/ Weight with base: 17 lbs/ Dimensions: 15.6"H x 18.7"W x 30.7"D) Hope this helps, I was wondering the same thing myself actually!! Good Luck!
I currently have a Grace Safeseat which I thought would be handy so that I wouldn't have to buy a second convertible seat for when my baby was over 22lbs but under one year. Many kids have to be in "fixed" rear-facing seats from 6 months on as they exceed the 22 lb limit of most infant seats. Well... I had a preemie so she didn't hit 20lbs until close to 16 months so had to be rear-facing until then. But I tell you, the Safeseat was still the way to go because she had surpassed the height limit of the Snugride (28") around 1 yr and was still able to be in my SafeSeat (height limit of 32") until she went forward-facing in a Radian 80. I loved being able to take her out of the car still in her carseat when she was sleeping until past a year! Also, not have a HUGE rear-facing convertible seat was nice. One con though, the Safeseat does stick out farther so only fit in the middle of our car or on the side with the passenger seat pulled up (we have a Subaru Forrester)
We have the SafeSeat and LOVE it... I too considered SnugRide versus SafeSeat and decided SafeSeat with no regrets. All SafeSeats have a front harness adjuster, but only some SnugRides do (front adjust is a must). Yes, it is heavier, BUT the point at which becomes a big issue is when most SnugRide parents are switching to a stay-in-car seat anyway, so set the handle at an out-of-the-way position and leave in car -- the extra $40 spent on a SafeSeat saved me from buying a $70+ convertible (at the point where your child is ready to face forward, I recommend a Graco Nautilus - it could be the last car seat you buy - SafeSeat+Nautilus=only 2 car seat purchases!) I would also like to take this opportunity to note that not many parents (including those with SnugRides) use infant carriers for long distances... PLEASE note that you should test out the seat in your car before you buy, no matter which you choose (Babies R Us should let you do this) Finally, slightly off topic, I would HIGHLY recommend Graco's mosaic stroller, and Graco's snugGlider swing with whatever option you choose. Hope this helps!
With the convertible car seats, I don't see why anyone would get safeseat. For next db I will get a snugride then use our convertible car seat. My db wanted a more "upright" seat asap and she was under the 1yo weight limit. The bucket seat becomes uncomfortable to them. You can use the covertible car seats up to 2 years rear facing, which is supposed to be the safest way to go. Then use them forward facing up to 65 lbs. So it doesn't make sense to get the largest bucket seat, besides you can't carry them in it after like 14 lbs.
I just wanted to mention that car seats do have an expiration date on them, they are molded into the plastic on the back of every carseat. The dates are typically 6 years from the date of manufacture. So even though it would seem you would only have to purchase two carseats, you may in fact have to buy more because of this. This is something that so few parents know about, but it is really important. There is a video on Utube showing what can happen with an expired car seat.
