I had a BMW 7 series which came with many way adjustable power seats, and the one that saved my back was the ability to lean just the upper part of the back rest forward or backward.

The local Lexus dealership has a limited new car selection and I sat in the ES, UX, and a GX on the floor. I sat in each one and was surprised to learn none of these had the ability to adjust the angle of just the upper part of the back rest.

I think this comes standard in most midrange-plus MB/BMW.

I think the Lexus LS comes with this ability. Not sure about the GS.

Does anyone know which models come optional with this feature? I'm in the market for a Lexus highway cruiser and I prefer to have this feature available.

 

how does the ability "to adjust the angle of just the upper part of the back rest" provide relief? not understanding the biomechanics of this unless you suffer from a unique malady

 

I have a rather long inseam and a short upper body. I tend to sit hunched over on long drives. Because of my unusual geometry, it is difficult for me to get my back and head to conform to the contour of the RX350's seat. Every part of my body above the shoulder blade does not rest on the backrest or the headrest. When I do force myself to conform to the contour of the backrest, I get sore very soon.

It's not a malady, but just a peculiarity of my anatomy which would be considered to be in the extremes of what's normal.

Because the upper part of the backrest of the 7 series is adjustable, I can adjust it so that it conforms to my favoured seating posture, so I don't have to conform to what would otherwise be a limited range of uncomfortable postures.

 

Have you tried tilting the backrest forward somewhat (rather than reclining it back) to allow more support of your upper torso? But tilting the seatback forward may reduce lower back (lumbar) support.

 

Yes, I have. But because of my peculiar size, I have to tilt the backrest forward by a lot for my back to conform to the backrest's contour, so far forward that I need to expend energy to actually keep my back pressed against the backrest, which of course is uncomfortable.

 

really not sure if even LS has that, but if any model would have it, it would be LS. Some models of GS also have 18 way seats not sure if that is part of it.

Lexus is good at making their seats comfy by default... never really been great with adjustability. Case in point - I got A7 now, and it has more adjustments and features than my old IS which barely had any, but in the end after 6hr drive I was noticably less tired in Lexus.

 

GS350 with lux package has more seat adjustment positions then the LS, it is 18 way, though I don't know about double adjustable upper seat. Lincoln Continental I think has 30 way power seats in a trim package.

 

no lol. The LS500 with interior upgrade package has 28-way power front seats with multifunction massage

 

I was talking about the LS460, I was assuming he was buying used.

 

Oh, I didn't see any indication it would be pre-owned, so if you say LS, I have to assume LS500. No harm no foul
