One of the things that immediately stood out to me with the Tacoma was the TRD Pro's crazy performance seats.
Toyota calls them IsoDynamic Performance seats and they're exclusive to the TRD Pro. They're equipped with four-way shock absorption to stabilize the driver and passengers while off-roading.
The IsoDynamic seats are adjustable, too, on the back of the seats you can dial back the cushioning "via levers on the seatbacks."
From Toyota's press release:
Debuting exclusively on the new TRD Pro is a segment-first IsoDynamic Performance Seat that helps provide a smooth, confidence-inspiring ride for those in the driver and front passenger seats. The goal of this patent-pending feature is to stabilize the driver’s field of vision to improve focus, comfort, and reduce fatigue while on rugged trails. The IsoDynamic Performance Seat uses an air-over-oil shock absorber system allowing for vertical and lateral seat movement simultaneously to dampen body movement and stabilize the head and neck to keep alignment with the spine. This dampening effect is tunable based on body mass and occupant preference and can be bypassed, if desired, via levers on the seatbacks.
