It's a typical first impression before I bought model Y i saw one youtube review one person criticized the seats. He had some back pain issues due to some medical conditions. After he drove model Y on o long distance 500+ miles he said he's taking his words back.
It almost scared me away also because it looks visual but I can confirm seats experience of tesla is very good. Musk in interview to Munro told they tried several contractors to produce a comfortable seat. Most cars outsource seats. They ended up producing their own with better ergonomics. They invest a lot with distributing the pressure/weight across entire seat.
Looking into getting a 3 or a Y next year myself.
