Britax Marathon Onyx Booster Car Seat

He's a very nice person. Good seller.
The legendary Britax Marathon™ convertible car seat is renowned for safety, comfort, and convenience. The Marathon is also one of many Britax products renowned for its ability to keep your child in a harnessed restraint up to 65 pounds.

This is our second Britax seat (our first is a Roundabout that is on it's third child and second cover, but still going strong). I just can't say enough about the quality of Britax's convertible seats. I have researched and compared TONS of seats over my years as a mom and for me, no seat comes even close to comparing with a Britax. The price may seem outrageous to some, but consider this--our Roundabout has NEVER had a recall and if you divide the price we originally paid ($200) by 3 kids, that works out to about $67 per child. If you add up the cost of what you would spend to get the same features from a cheaper seat (ex. Cosco Scenera--$50 for a seat, $15 for a pad to sit it on so your nice leather upholstery doesn't get scratched by the sharp edges on the base, $10 for strap covers and a belly pad, and around $50 for a seat cover with better padding because there is virtually NONE on the original, that comes to $125. Give up soda pop, coffee, beer, eating out, or whatever for a month or two and you can save up enough money to make up the difference. After all, it is YOUR CHILD'S SAFETY we're talking about. I feel much better about my 3 1/2 year old being in a well built, 5 point harnessed, nicely padded Marathon than in a toddler seat / booster of any other kind. I am totally spoiled by the little creature comforts such as the belly pad, thick seat padding, rounded base that doesn't cut your upholstery, and the velcro strap holders (best car seat feature EVER and I don't know why they all don't have them). At almost $300 new, the Marathon still works out to under $100 per child for my 3 little peanuts. Since it can used from birth to approximately 5 years old, that works out to $60 dollars per year, or $5 per month of one child's life--less than a large cappucino or one 12 pack of name brand soda pop. We have tried others, and we keep coming back to Britax.

It is a wonderful car seat and I highly recommend it. It is sturdy, top-rated for safety, and easy to get children in and out.

I bought this, our third Britax, as a back-up for days when my husband dropped my son off for school and I had to pick him up. We unbuckled and lugged a seat for a while until we purchased this spare. I usually would deal with that type of inconvenience and not have a spare - why spend the money? - but it was a huge hassle and I hate the idea of continually uninstalling and reinstalling the seat as there is always the risk of failure. Plus it was cumbersome to carry it with 2 little ones in tow and I have difficulty reinstalling it.

I recommend removing the seat cover and belts and washing in the machine when they need it. They come out so much cleaner. I air dry them. For the foam pad underneath the cover, I only hand washed it very gently on the few occasions it needed it (we've had a couple of milk spills that required this to be done). Be sure to get an idea of how it fits together before taking it apart as you need to reassemble it!

I have had one since my guy was old/big enough to be front facing. I loved it. We had a different seat in our other car for 2 years! I hated the other seat and finally decided to just buy another Marathon. They are more comfortable for my son. The straps don't get twisted. I love the velcro on the side to hold the straps. The seat sits higher than others, so he can see out better, which he loves! They also seem to hold the head in better position if the child falls asleep in the seat. I'll never own another brand again! Well worth the money!!!!

Recently we bought this carseat for my daughter when she turned 4. I wish I had bought it when she was first born. When my daughter turned 4 we put her into a booster seat like alot of parents, without realizing how dangerous these really are. When we were driving and I realized that her seat was nothing more than raising her height it scared me. She could easily slide out of the seat and after showing me how well she could unbuckle herself I thought that was enough and purchased this seat. There is so much room for her in this seat it's amazing! She's 44 pounds and is 42" tall, and has room to grow. It has lots of padding on the seat, and lots of roominess too. She enjoys being so high up and back in the middle of the backseat so she can see everything. I personally love the fact that it is so snug in the backseat. I drive a Pontiac Grand Prix and found this seat very easy to install (as easy as the others or easier) and doesn't take up as much room as you would think. Still room for 2 more passengers or even 2 more carseats in the back no problem. My only complaint is that there's not an optional cupholder that could be removed so it does make reaching to the backseat a little bit of a pain. Well worth the money.
