"Clever and clean! I always liked this cardboard furniture look. But seems like early concept stage. The ring is incredibly sturdy, I buy the 350 kg. But the two sheets on top, supporting people sitting right in the middle? I fear this will not last for long, short term usage or not. And People sweat... during Covid there were cardboard beds in India, using mattresses. I think it´s the same with these, found on google: https://aidboards.com/en. And as you can see there, Euro paletts are not 2m long ;)"
