    So this discussion has come up in spots, but let's throw a dedicated thread at it. We know the premium upgrades package gives you 12-way power adjustable seats.

    So what are the 12 ways and more importantly how do you control them.

    The below picture is of a production car.

    The controls match my current car which to the best of my knowledge doesn't have 12-way seats.

    So...

    Seat bottom:
    1 - Forward
    2 - Back
    3 - Up
    4 - Down

    Seat back:
    5 - Forward
    6 - Back

    Lumbar:
    7 - Up
    8 - Down
    9 - Out
    10 - In

    So what are the other 2 and how do you control them?

      Seat bottom tilt would be another 2 directions

        You beat me to it. Just sat in my car and realized the tilt control.

        So that settles the 12 and confirms my car is currently 12-way as well :)

          Base version seats likely will not have lumbar nor bottom tilt.

          +1 for the tilt control, that's what I was thinking too.

          Just had a Volkswagen Golf Wagon SE for my company car - pretty high trim level, with panoramic sunroof, 12 speaker sound system, Apple/Android carplay, etc. Only thing missing from compared to highest trim level was HID/LED headlights and TACC. But strangely, the car seat sliding forward/backward was manual. Every other movement of the seat was powered, but if you wanted to slide it, you had to reach under the seat for the lever.

          I'm guessing the base model seats will be something similar to this - powered in some ways but not in others. I doubt it'll be fully manual at this price point.

            They will be fully manual. I understand Tesla's philosophy of simplification.
            They will have TWO main wiring harnesses for Model 3 (plus AWD add-on harness).
            Base version will miss lots of extra wires, like gazillion speakers, rear seat heaters, fogs,
            wires for powering seat motors. PS: electric seats add a LOT of weight.
            Base version should have 3-wires for heated seats, 2 wires for pyrotechnic pretensioner,
            2 wires for buckle detection and passenger seat should have occupancy mat, 2 more wires.
            In case of electric seats with memory, it needs 2 more wires for power and one bus wire.


            Tesla even wrote that standard equipment will be 6-way adjustable manual heated seats.
            Imagine these levers, like older 3-series had (newer have front-back lever at front edge)
            [​IMG]
            As you see, 3 levers, one unlocks forward-backward motion, one height, one seatback.
            On cheaper vehicles, passenger often misses height control (4-way manual passenger). Not 3-series.
            Plus having height control missing on passenger will require another seat designs for RHD countries.
            This is not simplification in terms of Tesla's philosophy. KISS. Though I hope UP-DOWN movement
            is pump-style, as unlocked height control is pain in the ash like BMW had.
            If I had the chance to design manual seats, I would have two levers.
            One pump-it-up&pump-it-down style for up-down movement, another one unlocks forward-backward
            motion if pulled and same handle unlocks seatback if pushed down. Elegant and simple.

              I really hope not, I have a hard time with most seats if you can't tilt them, they all seem to be far to 'bolt-upright' these days.

              On the base the seatback will have manual tilt. The seat base will be fixed.

              I agree. But base seats will not have tilting bottom.
              Raising the seat will help though.

              For me, premium interior is much more valuable than premium range or premium look (wheels). I sit on the seat every day. Starting from first meter. I use extra range rarely. I hardly see my wheels. I always listen stuff from audio system. Therefore, premium interior is top priority on my list.

                Are manual heated seats ones that warm up due to your butt sitting on them? :D

                Sorry, couldn't resist. ;)

                  Are you sure on this?

                  If they don't even manually tilt (as in the seat base) that's a problem for me.

                  I've never heard of a seat with manual tilt. Not saying they don't exist, but I doubt they're too common. FWD, BACK, UP, DOWN, SEAT BACK TILT, and occasionally LUMBAR. That's all I've seen in manual seats.

                    Most VAG (Audi/VW/etc.) stuff has manual tilt (if not electric).

                      My 2002 Accord had "tilting" seat botoms. Instead if a single up down lever or something it was a front up/down knob and a rear up/Down knob. That's the only car I've seen that way though.

                        I've never seen a manual seat base that you can adjust the front and back independently up and down. Lots of the have a raise and lower lever for the seat base. Who knows? We wait and see.

                        Yep. I've sat on all those. BMW had offered manual seat back, manual slide, manual height, manual tilt, manual thigh extension, manual headrest height, angle, width & distance. Opel offered even manual 4-way lumbar (2 knobs).

                        We know that base seats will have 6-directions. Slide and seatback are pretty much mandatory. Now either we choose height or tilt. For driver seat, height adjustment is extremely important. Tesla will not skip that.
                        In case of individual posture problems one can use cushions. My gaming chair comes with 2 pillows. One for neck, one for lumbar.

                        lot of cheaper stuff in EU have separate front/back height adjustment, this effectively serves as tilt as well as height adjustment.

                        I'm wondering if the lumbar height is settable. I suspect it's just "in/out." The button looks like it's just a horizontal toggle.

                        12-way seats in VW (for instance) are thus, with 2 degrees of freedom for each:

                        >fore/aft positioning
                        >seat height
                        > seat depth
                        >seat cushion angle
                        > backrest angle
                        > lumbar support in/out

                        Seat depth?
                        2-way lumbar is often useless.
