The IsoDynamic seat is inspired by the Lexus Kinetic Seat, a 2016 Paris auto show concept that featured spiderweb-patterned hammock-like supports instead of cushions. The design allowed an occupant's torso and hips to move independently in order to keep the head stationary. Toyota developed the Tacoma TRD Pro's Iso Dynamic seat to accomplish the same goal in an off-road context.

Think of the IsoDynamic seat as a seat within a seat. The cushions rest on an inner frame that attaches at two points to an outer frame (which itself mounts to the vehicle body). One attachment point is high on the seatback, and the other is a ball joint hidden below the front edge of the thigh cushion. Between these, the seat swings side to side like a hammock, up to an inch in each direction.

To regulate the IsoDynamic seat's movement, the prominent vertical reservoirs contain pistons that compress chambers of air. The right strut works against lateral swing, and the left one restrains up-and-down motion. Below each piston, oil flows through hoses to pairs of remote cylinders affixed to the seat.
