The Comfort Sport has a very low RF weight limit of 30 lbs, and a very short shell and low top slots.
It is outgrown both RF and FF VERY young, I've seen posts where 18 month old children have outgrown the seat completely.
Not worth the money.

The Evenflo Triumph Advance will last a good long time., it has a 35 lbs RF weight limit and a 50 lbs FF weight limit.
My 5 year 11 month old (who outgrew her Marathon at 5 years 9 months) would still fit in one.

	Forward Facing Car Seats A forward-facing car seat is one in which the child sits facing the front of the car. The seat should be installed in the back seat of your vehicle. Most forward-facing only seats are for children above 20 pounds.

	Rear Facing Car Seats A rear-facing seat is one in which the infant faces the back of the car. Always install a rear-facing seat in the back seat of your car. This is the safest position for an infant. NEVER place a rear-facing seat in the front seat of a vehicle with passenger airbags.

	Britax Marathon - Click for more info Increasing the time a child can safely stay in their convertible car seat is a big issue and Britax engineers have come through in a big way with the introduction of the Britax Marathon with LATCH. A LATCH Compatible Convertible Child Seat, the Britax Marathon can be used rear facing 5 to 33 pounds and forward facing from 20 to 65 pounds. Compare the numbers and you will see it is hard to find a seat with these weight limits that is safe and functional.
