The
BRitax seat will hold to 80lbs in the harness. It is the tallest, highest weight harnessing seat on the market. I own 2 of them and LOVE them. I have been able to play with the
Safeguard seat, but I believe it only harnesses to 65lbs. The
LATCH is really cool. IT automatically tightens and loosens...that's why there is such a high sticker price on it!!! If your child is the only one in the vehicle and there is a tether anchor in that location (I dont' have my
latch manual in front of me), then it should work.

IMMI has a world-renowned reputation for creating and promoting the highest rated safety harnesses and restraint systems available today, from integrated child seats in production vehicles to campaigning for increased use of safety harnesses on public transportation systems. Based in Westfield, Indiana, SafeGuard has been creating and testing essential components used across the child safety seat industry through their state of the art crash testing facilities since 1961. The SafeGuard and SafeGuard Go are IMMI’s first direct foray into the child safety seat market, and the results are simply outstanding. No other car seats or boosters are designed with as much attention to structural integrity, ease of installation, and total child safety. This seat has been subjected to the most thorough and extensive testing “ever conducted in the industry”: virtual prototyping with computer models; rigorous front, side, and rear impact crash testing; and environmental testing in a range of climates and road types. | |  |
