BRIDE’s new flagship model. A new-generation reclining seat that combines a high level of holdability and convenience

STRADIAIII has a newly designed monocoque body shell with a bone frame and ZETA IV designed by 3D-CAD. The seat rigidity and strength of STRADIAIII have been greatly improved compared to STRADIAII. In addition, its newly-developed reclining mechanism and one-touch reclining lever, which aim at maximal operability, convenience, and durability, achieve more reliable holdability and comfort by suppressing backlash and vibrations through stepwise adjustments. What’s more, a belt hole for a 6-point harness has been newly installed on the back of the seat, which uses a specially designed high-density urethane foam for its seat and thigh cushions.
STRADIAIII is a new-generation reclining seat that combines the holdability required for circuit driving with the convenient and comfort required for everyday use at a high level.
It is available in three colors, namely gradation logo, black and red, two types of shell, namely FRP silver shell and super aramid black shell, and two types of cushions, namely standard and low type.

Specially designed seat and thigh cushions.

The specially designed, high-density foam molded urethane used for the seat and high cushions applies body pressure evenly to the flat seat surface in order to provide a strong hold and reduce fatigue. What’s more, it does not easily squish and has excellent durability. In addition to the standard type, a low-type thigh cushion with a thickness reduced to 2/3 is also available.

Belt holes compatible with an FHR system and 6-point harness

A large-diameter belt hole compatible with FHR systems such as HANS, as well as a 6-point harness belt hole, which has often been requested by STRADIA users, have been newly-installed at the bottom of the seat. This allows drivers to enjoy circuit driving and various other motor sports in greater safety.
