What are the 4 heights of the bench?

Heights are between 18" and 21"

I weigh in about 280lbs and can comfortably sit on one of these with no creaking. Hope this helps.

What are the exact dimensions of the seat?

Height = 19 1/2 inches high; width = 15 1/2 inches wide; and depth = 12 inches from back to front (deep)

What is the exact width of the chair when it's collapsed? I'm trying to make sure it fits in the narrow space I plan to put it in.

With legs laying flat it is 24" long. If you screw in the 2 knobs that hold the seat open, you'd need a max of 5.5". You would need a minimum of 5.25". (I assume you're standing it up and sliding it in) The width of the seat remains the same at 12.25" Basically, folded and standing up on the legs: 24" tall, 5.5" wide, 12.25" deep.
