I travel a lot and I often need to work in the car. The seats are wonderfully comfortable and supportive of my bad back. I had a Mercedes S Class for about 7 years, and the seats in that were excellent, but although they were supportive and comfortable, they weren't "cosy". In the LS 430 I feel as though I have a large lounge full of really expensive arm chairs.
