Minimum child weight?

40 lbs ... It may depend on specific state laws, too. You may want to check out your state requirements

Not sure what the "limit" but my 4yr old was 39lbs when we got him the seat. He's a skinny tall kid

Your state laws may vary. But here is a rule of thumb. To move from seat type to seat type - meet these minimum requirements (all 3) Move from a car seat to a booster with back @ 3/30/30 meaning 3 yrs old + 30 inches height + 30 lbs weight. Move to a BACKLESS booster at 4/40/40 meaning 4 yrs old + 40 inches height + 40 lbs. Move to just a seatbelt at 5/50/50 - at least 5 years ago and 50 lbs and 50 inches tall.

I don't know the minimum. The maximum is 80 lbs. This is a great little booster for a reasonable price. We've been using this since school started this year, August 2012, and it's very durable. If your child has outgrown the car seat, this is a good next step.

Small I am assuming. Though those may even be too big if your child is petite.

Get the maxi. The weight limit printed on the bottom of the mini says 40lbs. Your four-year-old, no matter how smaller, will soon hit that.Our 4.5yo is over 50lbs and still rides the mini, so the mini is quite resilient, but I don't think you lose much by future-proofing with the maxi.and our two-year-old has been riding the mini for several months now.

We had kids aged from 2-10 and they were ok. I don't remember them being big for them.

I don't think there is a minimum...my son was a month old when we purchased the chair (he was about 8 lbs at the time) so he could get a different perspective other than lying on his back all the time. And he did fine in it. :)

Great question! One I wish I would have looked into before buying this system. This system is for babies up to 22 pounds. The Keyfit 30 will go up to 30! Wish I would have known that before buying.

I believe the lowest weight is 5lbs. But I would personally prefer an infant Carseat simply because if your baby falls asleep you can take the infant Carseat out and not gave to wait up your newborn. My preference! But I do love this Carseat too...

I don't think there is a minimum height, but the toddler needs to be able to ealk and climb one stair. What's nice about this stool is that there are railings/ handles for him to hold as he climbs up.

I think there are 2 sizes but the min age is 3 yrs. I also think there is a weight requirement but I know my kid was well past the minimum weight by the time she turned 3. We love the thing. A great space and time saver. Goes with the kid, not the car and eliminates the need for every caregiver to have a car seat.

I'm not sure what the minimum is but my daughter started using this at around four months and at the time she couldn't sit up either. The seat in this chair was deep enough to provide her with support to play comfortably.

Yes You Can. The minimum Recommended Weight is 25 lbs. The Head Rest Is Adjustable so it can lower and raise to meet your childs needs .

I think it depends on height and size of the infant, coz some infant weighs less than 30 lbs but taller and some are shorter.

It depends on the length of your kid more than the weight because it is on the floor so weight isn't too much of a problem. My guess would be somewhere between 0 to 2 or 3yo.

My oldest is 7yrs and approx 60lbs. It's fine for him now, but another 15-20lbs and I may start to be mindful.

Hi That would be tiny. the smallest child size we carry is 8. Just curious, how old is a child that is size 6?

My daughter didn't have a problem. My grand-daughter is rather light, so it could be a question of weight.
