I have a turn a tot car seat and the straps that hold her into the seat are to long and i can't work out how to shorten them and i can't find instructions anywhere

it does not go by age, it is based on height and weight.
Rock A Tot is not a recognized name on their website of current or retired models.

It is a model from the UK-
Weight/Size Suitability
------------------------- The Rock-a-Tot is a group 0 car seat, suitable from birth up to 13kgs (around 9-12 months). It uses a three point harness. For a newborn this seat is lovely, the head hugger makes the seat very snug and secure around their head. However I did find that as my baby got older the head hugger seemed too confining and we removed it when he was about 4 months old.
The shoulder straps can be adjusted to 3 or 4 height settings allowing a good fitting as you baby grows.
Although this seat is designed to go up to 13kgs I think that most people chose to move their baby out of this seat when he/ she reaches 9kgs and put baby into to a forward facing seat. Adrian was a large baby to start with (9lb 9oz) and also long. By the time he had reached 9kg's (around 7-8 months) his legs had to be bent slightly with his feet touching the back seat which we didn't think would be very safe in an accident (as surely more pressure would be placed on his legs if the car seat moved towards the fixed seat)and he was getting rather squashed in to the seat.

Found this solution on this website, and works great!

What seems to be a sewn-up loop, is actually easy to unattach, but the trick is not explained in the manual.

Where the end of the strap seems to be holding to the seat's plastic shell, the plastic is not completely connected, there is a break in the plastic. Just move the strap left/right a bit and you will see that you can unattach it there. Then you can unthread the loose end of the strap and completely remove the cover.

hi

are you pulling on the strap that comes out the front of the carseat.

or are the straps too high above your childs shoulders .

do you need a manual?

mcdevito75 here, I imagine you mean a Band (metal) they can be shortened by removeing links from the band itself, you"ll need a specific tool called a link remover tool. they are available on ebay. However by the time you get the tool and the time to do the work, and if you don"t do any work on watches, the best bet is to look for a small watch repair shop in your area to remove these links. Hold onto the removed links for later replacement. If it"s a Strap (material) on your watch, say, leather, rubber etc. simply cut the excess strap at an angle with scissors.

Remove the large bar holding the bottom plate. One side will have a plastic retainer which you just move to the side and pull the barr all the way out from that side. There is a rear leg that you can pull down and back which will make the seat sit more upright. Remove the strap (it is one solid strap) and be sure to save all the parts if you plan on giving it to a needy family when your child outgrows it. The center clip is easy to remove, turn the seat upside down and find the metal retainer and pull it up, turn 90 degrees and feed it through the hole and pull on the other side. Now you should have a strap/clip free seat that will be a "seatbelt positioning booster seat".

you need to turn the car seat over and on the very bottom there are two gold rectangle-shaped clips holding the straps. You can pop these out and feed them through the hole....not like other car seats where the straps unattach up at the shoulder end.

Try contacting Maxi-cosi through their parent company http://www.dorel.co.uk/contact-us

First turn seat upside down. There should be a slot on each side under the seat, run strap through each slot and turn back over. Pull strap up evenly, put on clasp part on each side, then put chest clasps on, run your straps through back and secure to strap comes between legs.

Well the best solucion is to cross shoulder straps and buckle it like that because soon they will learn how to take them of if you don´t do these: The straps have to be criss crossed on there chest  Hope these helps

need to adjust straps
