A fluid ejection device includes a fluid chamber having a first sidewall and a second sidewall, a flexible membrane extended over the fluid chamber and supported at an end of the first sidewall and an end of the second sidewall, an actuator provided on the flexible membrane, a first gap provided between the flexible membrane and the end of the first sidewall, and a second gap provided between the flexible membrane and the end of the second sidewall, and compliant material provided within the first gap and within the second gap. As such, the actuator is adapted to deflect the flexible membrane relative to the fluid chamber.
