Technology GCSE

I'm starting my GSCE Design Technology project and I have decided to create a footstool/rest for the elderly. I have very little knowledge and experience in this area and I would like to ask what would make you buy a product like this?

It would be useful for as much detail as possible, I have listed below some important questions that I would like answered.

Would you prefer a footstool (a small stool or table to rest your heels on) or a footrest (an angled panel that you put the soles of your feet on that you can push against)?

What design style would you like it to be based on (modern, 80s, 70s etc)?

Roughly what height would you prefer it to be (ranging from around 15cm to 45cm)?

What material would you prefer (Please try to be as specific as possible, for example, dark oak wood rather than just wood)?

Is there anything else you would like it to be (for example, it could have a place for a drink or pack away so it is easy to move around)?

Thank you very much for your time.
