The chairs are super comfortable - otherwise we wouldn't have bought them. Form follows function. It doesn't help anyone if you have super stylish chairs and everything hurts after sitting for 30 minutes.
If you ever see them: try them out. At first, I only liked them visually and was very skeptical about whether you could sit well in them. The first time we tested them was at a garden exhibition, and we were amazed at how comfortable they were.
For two years, we’ve had the chairs in light gray in our barista bar here in the office, so I’ve been able to try them out quite often. Without a seat cushion or the furs we have now, the cast aluminum can feel a bit cool - although this is much less noticeable with underfloor heating than in the café, where the chair stands on an unheated floor. But that’s really the only drawback you could criticize.
