Hello, I have two questions: - I'm 6"4, will I fit comfortably in this chair? is it made for people my size? -what's the difference between type A & B?

What is the difference between Type A and Type B?

How high is the seat?

What are the total dimensions of the chair? Height from floor to highest point of the chair. And depth from the front to the back - so I know how much floor space it needs.

Are the dimensions really as shown in the photo? 84 x 53 x 56cm seems big. Also, I can't make any sense of the cushion sizes quoted.
