On Sunday in Germany I went to FC Koln, one of the new stadiums built for the world cup. Very smart, very modern, has Safe Standing areas for home and away fans and is generally rather impressive.
Anyhow, as the standing tickets were sold out we had seats in the upper tier, which was VERY steep and had a great view. As it's steep there are barriers (probably 60-70cm high) along each of the rows of seating. These didn't obscure the view at all. If you follow the link below you can see this on the first picture, right side.

I thought to myself how sensible this was. The FLA tell us about the risks of standing in seated parts and the dangers of cascade effects and the like - even though their claims are a bit (!) dubious, people do often fall over seats and pick up injuries while celebrating goals. Even if everyone sits in their seats during the game the FLA accept both that people will stand at exciting times, and that this is when standing poses the greatest risk. If passive standing is so serious a problem that it can cause threats of stand/ground closures, by logic it is dubious whether any seated areas should obtain safety certificates.
Under the FC Koln system, the risks of falls are virtually eliminated. Although there was no persistent standing in seated areas at the game (amazing what giving people a choice does) the Germans recognise that people are going to stand at times - hence creating seating areas that are safe for people to stand in. Never mind Safe Standing, is Germany the home of Safe Seating too?
