Harness adjustment on Britax Marathon 70 Convertible Car Seat Can anyone tell me how the harness straps are re-adjusted for this carseat. I don't want to have to unbuckle the carseat to adjust the harness, but I'm unsure on this model how it's adjusted. Is it on the front/top? Any help would be appreciated, looking to buy this one within a few weeks.***Thanks Mark! I bought the Britax Marathon in Blue Print on Amazon and we (including my 11 month old) love it. I'm taking my 5 year old and 11 month old to visit family in San Diego soon and purchased the Traveling Toddler strap to turn my rolling carry-on and my Britax into a stroller.

Hi Carrie, I measured the backseat of my outback. It measures approx 50 inches across. I hope this helps with determining if the marathon will be too big for your forester. The marathon fits great in my outback. I'm 5'4" and my hubby is average height and we don't have a problem with not being able to sit comfortably in the front. Good luck!

There is a latch at the top of the seat that you pinch and pull up. Super easy and so much nicer than on my graco where you have to rethread it. Go on the Britax website and you can watch the video! So easy to install and adjust. We bought two for my 10 month old twins. They took a couple minutes to install. Awesome!

I have done a lot of research on this! I have a subaru outback and needed a relatively slim seat to use rear facing. The marathon and boulevard use the same shell so they are the same size seat. Both rear face up to 40 lbs. The boulevard has a lower height maximum than the marathon for both rear facing and forward facing. The boulevard has a lower weight maximum for forward facing. The marathon is a fancier seat without any added bulk.

Does anyone know the difference between the Marathon and Boulevard? Looking to buy a convertible seat for my 1 year old who is outgrown the Graco Snugride...keeping him rear-facing of course...thanks.

Britax marathon 70 I cannot adjust the STRAPS (make looser) on the baby seat. we are no longer able to connect the straps to the red "buckleet" in the center. I have found the latch at the top of the seat--but it only slides the seat up and down. PLEASE HELP!

I have a Subaru Forester that has a surprisingly small back seat. Our Chicco KeyFit 30 barely fits in the back seat - we have to put the front passenger seat almost fully forward for it to clear (not pleasant for the adult in the passenger seat). We want to switch to a forward-facing car seat, and are very interested in the Marathon, but I don't know if it will fit. The Outback does have more room in the back seat than the Forester, so I'm not sure. And we can't test it out in advance since we live in China and will need to have it shipped. Any thoughts?

Has anyone found something similar that will work with the Britax B Safe Carseats (especially in price)? We've got twins on the way and I'd rather get something like the Britax B-Agile double for long-term use, but it only holds one car seat. Can't see that long-term, the babies/toddlers would enjoy the front-back configuration of the B-Ready stroller, especially being the same age and all . . .

The car seats were purchased for our granddaughters. The were installed on their fathers auto. I know the four year old does buckle up and unbuckle the seat by herself. Don't know about the adjustability, but we were given specs by their dad and I am sure he would be aware of the adjustability. Hope this helps.

It can be placed rearward and there are different adjustments for the buckle and the harness (shoulders). I used a Graco bucket - carry kind for first 4 months but my baby was heavy to carry so i changed to the Britax. I researched the safety tests and the Britax 70 was rated #1. Definitely worth the money. It will last her for years as it is good up to 70 pounds and the adjustments allow the headrest to also raise.

My son is five and weighs 45 pounds. He was about your son's size when he was 2, but then he thinned out. This thing is good up to about 100 pounds for front facing five point restraint. The five point restraint is simply the safest. We also have a booster for when he goes with family or friends, as this is not as convertible. But, overall, I love the britax 5-point restraint seat for longer trips especially as when he nods off his head has a place to rest. Your son is only 2, so I would recommend investing in this. Poorly fitted boosters can cause evisceration of organs and spinal cord injury to children. Why risk it? My son is five and weighs 45 pounds.

I would also like to see someone address this. I have a 3 1/2 year old who is in the lower percentages for his age. He is 33 lbs and so it says (on the "fit my child" part of the Britax website) that either the Advocate or the Frontier would work for him.The differences I see is the Advocate sits up slightly higher, and it reclines.But the Frontier has arm rests and cupholders.

It is very tricky to adjust this seat. (before I start, make sure to check the manufacturers instructions, they are the tested way of doing this). My first recommendation is get it "close" to the correct tightness without your kid in the seat, then buckle your kid into the seat. When tightening, try pulling the tightening strap down then up - I have to pull quite hard. That may help. Otherwise return it like I did - it is not a good design in my opinion.

We're having the *exact* same problem as scientific illustrator. The Britax Roundabout will not sit securely in the middle of our Prius. The car seat base is more narrow than the middle cushion so the car seat tilts and wobbles. We are trying to return the Roundabout and are looking for suggestions on which convertible car seat will work. Please advise!! Thank you

I wouldn't recommend moving her up to the Britax Parkway SGL just yet. My son was 4.5 and in the 85th percentile for height and barely 40 pounds when I moved him up to the Parkway SGL. After a while some kids find the Marathon uncomfortable, but at 2.5 I would suggest perhaps trying the Britax Frontier, which has a bit more room in the 5-point harness than the Britax, so thte straps might be a bit more tolerable for your little one. And once she is ready for a booster, the Frontier will easily convert.

I just checked the Britax website, and as I suspected, there is a height limit that most children will reach before they reach the 90-pound weight limit. The five-point harness is for children up to 58" tall. Also, the shoulder harness has a height of 20.5", so a child with a long torso could outgrow the harness before reaching 58". I have a 47" seven-year-old with a short torso who will likely be harnessed until he's about ten with this seat. He does have some friends who are over 50" tall and in the 55-65 pound range at seven or eight years old.

I do find it more difficult than our other Britax. I always have to readjust the shoulder straps and make sure the chest piece is in correct position for it to tighten correctly. Pulling straight out is the only way it will work though. Good luck!

Hi Camila, I was very disappointed to find out that "it doesn't" the way the prior models do, which as you may know, you just pull the handle between the child's fit and adjust, that easy... this model has 3 different positions but you can only change it by removing the carseat from the seat, adjusting the new position pulling a lever from the bottom back of the carseat and then installing it again, witch is very disappointing to me, I have 4 children (always have bought Maxi-Cosi) and that was the main thing I loved about this car seats.. the child is asleep, pull and change position, the child woke up, pull and seat him/her up again, sadly doesn't work like that with this one.

I have the Britax B-Ready stroller and all I had to but was this second seat. I later decided I also wanted the lower infant car seat adapter but it was not necessary. My two year old fits comfortably in this lower seat when I have the infant seat on the top and/or when I have the bassinet. The infant car seat adapter is to put the infant on the bottom whenever I want my two year old on the top. I hope this helps.

I am using it for my newborn...now almost 3 mo. I originally used it in the convert able car seat, since we did not have an infant seat. He is nearly 16 lbs now, and it us getting a but snug. Also, I was thinking of altering my original post to add that the top and bottom should be able to be adjustable , since you can take them apart with Velcro. However, if you do try to separate the top from the bottom and extend the length, the harsh part of the Velcro goes against the baby's back.

The Chicco Nextfit! I exchanged two Marathon G4s for the Nextfit. The Nextfits with the nine adjustable positions leveled better in our cars, and they were easier to adjust for our two year old. Lastly, the G4 took 15-20 minutes to install rear-facing using the tether whereas the Nextfit was solidly installed in two minutes. Addendum - I also felt that the Nextfit cradled our son's better than the Marathon G4 (e.g. his head stays upright in a neutral position while asleep.) Lastly, Chicco customer service is fantastic! We need replacement parts over the years for various Chicco strollers, a play yard, and a high chair, and they always responded wonderfully! The Chicco Nextfit!

I had the same problem. After looking through car seat installation guides online, I figured out that for forward facing seats such as this one, the straps for the harness needs to be threaded through AT or ABOVE the child's shoulder. Mine was set a little below, because that's the way we used to do it for the rear facing seats. Once I fixed that (it's now just a tad above my son's shoulder), I have no more problems tightening the harness. If in doubt, contact Britax as they steered me toward the right direction.
