Three Ikea stacking chairs from the 1990s.
They are strong metal and the seats have a bit of a cushion in the slightly soft seat.
You can easily stand on them when you don't have a step stool.
They are very useful, and thus they do show some wear. Over time the seats became a bit discolored and the black on the metal has a couple of chipped places.
They'd be great for enclosed porch seating or extra guest chairs.
