I voted 1/4 closed cell Volara but its my only reference point. I like the feel a lot my only complaint is that if you leave things on it it can leave impressions. I used my table as a desk the other day and my laptops rubber feet left impressions. I think after a day they bounced back completely
1/4" open cell from YAT. When I joined here and started building my table, Tony had mentioned that he was just starting to move to open cell. I prefer things to be a little durable and not require too much babying. I like the thickness for card scooping and it has the right amount of give. I would reorder for next time.
