Darn, I just turned down the "S" model because the salesman said I couldn't get standard seats. I'm just too wide for the sport seats.Sport seats will have much more aggressive bolstering on the thighs and torso and have an extendable thigh support as well. The standard seats only come in leatherette or leather/cloth combos - no leather.
It's worth noting that starting with March 2015 production, in the US at least, you can now order the Cooper S and/or the fJCW with the standard seats and opt out of the sport seats. It's feature code 4FB.
Im a big guy and i ordered the S with the sport seats. Test drove the S with sport seats, and they were snug, but thats why they are sport seats. My wide bottom will stretch them out over time.Darn, I just turned down the "S" model because the salesman said I couldn't get standard seats. I'm just too wide for the sport seats.
