Great idea

Two uses in one: it’s both a bench and a tree guard

These free public battery chargers for smartphones

The bus stop with swings

And the alternatives to benches — public hammocks!

The fold-out chairs which look like tulips

The bench which is also a table

These designs for a bench, staircase ramp and rain shelter

The pubic bench which you can turn over after it rains and sit on the dry underside

The reflective garden fence which changes appearance depending on the season
