I've chosen this for the seat. Only £10 delivered - I have no idea how it's possible to make and deliver a chair for that money and though I ordered one they sent two!! The chrome metal work will get added to the pile of steel in my garage. The seat itself is 3.9KG. A little heavier than I'd hoped but the lightest one discovered after hours of searching that was any use was 2.2KG with a much lower back and in white which I didn't want. I doubt I could have made anything as comfy and good looking less than 3.9KG and certainly not for less than a tenner.
