To wonder if there’s a small car which has flat seats?

[TwinkleInMyEye2020]

They all seem to have bucket seats which is terrible for my sciatica.

Are there no small cars out there with flat 180 degree seats?! Please somebody tell me there’s one I haven’t discovered yet.

I don't know the answer to your question, but might something like this work for you?

I don't know even my fugly 7 seater has slightly slight bucket seats

@Scarby9 thanks, that’s not a bad suggestion. Was looking at a Polo which has super raked seats unfortunately, which I think any cushion or device would struggle to remedy.
