I wanted another folding bench. I bought from Amazon rather than ebay, because I thought the descriptions, and especially the weight, would be more accurate.
I bought this one:
https://www.amazon.co.uk/dp/B08BRC44QT
It looks remarkably similar to one we've had for years, which weighs just under 4kg. So I thought "Weight: 2.2kg" was because of advances in material and design over the part 15-20 years.
It arrived. Just under 6kg! Back it went...
[EDIT: Just noticed it also states "0.66 Kilograms" Why don't people check this kind of data!]
