How to loosen the straps on envenflo tribute carseat?
This is about all I could find for you. Hope it helps.
Had one - its a huge pain in the **** and I always busted my fingernails doing it. The metal clips have to slide over the bumps to get them out. I hated that thing. May I make a suggestion? Return it. lol . I'm figuring you got a combo seat - Evenflo Generations, Bolero, Chase, that is a forward facing only seat to 40lbs, or a convertible seat like Evenflo Tribute that is forward facing to 40lbs. Since I don't know her age its hard to make a suggestion, but for just a little more money (we paid $79 for our Chase) you could get a much better seat. If she needs a convertible that will rear face, get the Evenflo Triumph for $150 or less, The Evenflo Triumph Advance (not the original Triumph, make sure it says Advance) is a great seat. $150 version at Babies R Us has padding similar to Britax seats, top slots of 17", harnesses to 35lbs rear facing, and 50lbs forward facing. $120 Walmart version just has little less plush padding. Wide open belt path, easy to install, though it doesn't have built in lockoffs. The harness adjusts at the front of the car seat, you don't have to take the car seat out of the car just to raise/lower the straps. It's one of only 2 seats that does this (The Britax Boulevard is the other, I believE), and it has infinite harness adjustment so the harness always fits perfectly until its outgrown. No more tugging straps to tighten them either. You tighten and loosen the harness using knobs on the side of the seat. As a major bonus, it can be used in a recline position even in forward facing mode. Awesome for kids who still sleep in the car. I LOVE THIS SEAT! LOL My son, who is too big for every other car seat at Walmart has the same amount of room in this as the Britax Marathon.
If she is forward facing (over 30lbs and over 2years old) then a Graco Nautilus would be a lot easier to use and install, $150. Harnesses to 65lbs and then becomes a booster, will be the last seat you have to buy her. Metal reinforced.
Combo seats are usually a major waste of money, as they only harness to 40lbs, no more than most convertible car seats, so you're really not getting any more use out them then the convertible seat.
