I took the cushions off of my Graco Head Wise 70 Model # 1859954 Car Seat to clean in the washing machine and now I can't figure out how to put the straps and belts back together.. I'm having no trouble putting the cushions on the seat but PLEASE HELP I can't figure out how in the world the straps are supposed to go. Thank You.

Bring the straps up through the holes on the bottom of the seat, one on each side. The metal plate on the end should pull in flat and snug against the plastic. Slide the buckle pieces back on, making sure they're facing the right direction to snap in. Slide the chest clip back onto both straps.
Place the ends of the straps through the slots you want the harness at (at or below the child's shoulders for rear-facing, at or above the shoulder's for forward facing), making sure that they don't twist. Pull them down low behind the seat.
The adjuster part of the strap has a kind of Y shaped metal plate - pull it up to meet the ends of your straps, making sure that it
doesn't twist, either.
There are loops at the end of the harness straps. Feed the curved part of the Y through the loop of the strap that's on the same side of the seat. Pull it all the way through, so that the fatter part on the ends of the metal plate are exposed and curve around a bit beyond the strap so that it doesn't slip back off. Do the same with the other side.
Now adjust the harness to fit your child. When it's tightened properly, you should not be able to pinch up any slack, lengthwise, at the hips or shoulders, and it should lie in a straight line down the front, with no drooping. Also adjust the chest clip - it should lie even with your child's armpits - not up in the neck, and not over the belly, where it can't do it's job properly. (It's job is to hold the straps over the center of the shoulders...if it's over the belly, they're likely to slip down off of the shoulders in an accident or sudden stop and also poses the danger of internal injuries.)

One other thing - car seat harnesses should never be submerged in water, as it can damage and weaken the webbing. They should only cleaned with a damp rag. If you put your harness in water when you washed the rest of the seat, I'd strongly recommend contacting Cosco (contact info here) to order a replacement harness.

Yeah its a bit tricky. ON the fron of the car seat there is a strap that goes intot he seat and has a button to lossen it. Press it down to lossen that strap then flip seat over and on the bottom you will find other end of the same strap and it has a brass t-fitting. Take it and pull it up the back side of seat and the shoulder straps fit into the brass fitting then tighten by pulling strap in front of chair.

HAve fun ;)

would assume you're talking like a booster seat with the back just no 5pt harness. You just buckle them up like you do. If they have those arm rest looking things, the part where it buckels goes under that one arm rest and the shoulder strap should go resting over his shoulder like yours. Some of them have a loop up top for the shoulder strap to go through. Just make sure that the toddler does NOT put their arm over the shoulder part of the belt. If you get into an accident this could break his/her ribs.

I had the same problem, so what I did was look at the first picture from walmart.com's page with this car seat.
http://www.walmart.com/catalog/product.do?product_id=10843110

I noticed where the straps went through the restraint systems, and remebered that I took the bottom ones out last, so I'd put them in first.

Then I threaded the straps through the buckle parts that snap to the bottom buckle, up through the buckle parts that snap together, then back through the holes in the cover and seat at whatever height your infant is. After that you secure it in the back like the sticker at the side indicates :)

I hope that's clear enough!

There is normally a splitter in the back, a metal piece with two hooks that is attachted to the adjustment strap. the sholder straps latch onto this. You can locate the appropriate manual here: http://www.coscojuvenile.com/usa/eng/Instructions The pages in the back normally discuss reassembly after cleaning.
