I've decided to go with a full chair that includes storage, pressure sensing, alarm features, and lights instead of only the smart cushion. The metal frame of the chair can be manufactured using the die casting method, the light will be created by electroluminescent wire, the timer dial will be made of plastic, and the pressure sensor and Arduino will be completely off-the-shelf elements.

I chose die casting for the chair because it is a rather large metal structure that can't be injection molded or 3D printed, and I didn't think machining was an efficient solution because such high precision is unnecessary. Die casting is a good larger-scale solution that provides just enough precision at a reasonable price.

Also list what parts will be designed and manufactured yourself and what will be off-the-shelf.

The pressure sensor, electroluminescent wire, Arduino, and timer can be off-the-shelf, while the chair portion will be designed. The first four are relatively commonplace and can be easily bought, and the chair will be the structure I create to make use of the other elements. The lighting and alarm features come together to provide a multifunctional chair.
