Is there any possibility to improve chances for rendering of chairs(tagged as amenity=chair)? I know this might be considered as “tagging for the renderer” and such a topic might be a precedent, but also may be beneficially. In this area(South park, Sofia, Bulgaria) you could see many chairs marked(check “Map data”). With @Dimitar155 we agreed we do not talk about park benches, but chairs in this case. They have been located there for many years. Unfortunately, I didn’t make any photos of them, but they might be somehow seen on satellite imagery(MAF Orthophoto). Some of them have backrests, other-not, with capacity for one person. They resemble this chair a little(3 of 4 image), but not completely. If a person uses OSM-carto, other layer on osm.org, or any app which visualizes benches, but he needs to sit at this moment, and benches are not so close to him, the chairs in question will be missed.
You could say there is outdoor seating in the area, but the actual chairs can’t really be mapped in OSM unless they’re fixed in the one position all the time.
There are such chairs not only along the area of examples given. You could see some of them appearing also on Esri Clarity beta images, which are quite old. These ones, shown on the first image are not a part of Barbecue&bar. Nothing in common. They’re like Node: 13921367695 | OpenStreetMap , Node: 13043152171 | OpenStreetMap for instance. They are not movable.
I think I’ve also mapped these as benches. As in your photo, I’ve come across them as part of a group of benches of various sizes, all fixed to the ground. It feels a bit odd to say that the small ones are a different type of amenity to the large ones. To be honest though, I didn’t know about amenity=chair, so I can’t say it was a reasoned decision.
This park is a good example - it is near me but I am not the mapper in this case. There are lots of benches/chairs scattered around, and they have been mapped with the seats tag, so the “chairs” have seats=1. That seems sensible to me, as it applies a uniform approach to objects that have a uniform appearance in the real world.
