What is the max weight for carex rolling walker ..A228 1011 001782

Can you specify which walker you are referring to? We do not have one with that number.

What are the dimensions of the replacement seat?

The dimensions are 12” x 14.5”

where do I find the serial number?

The serial number can be found on the box it came in or somewhere on one of the metal bars that support it.

How does that black cord attached to the frame under the seat work? I know it starts the folding process, but how is it wrapped after folding?

It is a solid bar that initiates the folding and doesn't need to be and can't be wrapped.

Will this height adjustment knob fit my Carex Rollator walker model#A221001702002379CB ?
