[Closed] Any 3D design or product professionals out there? (esp. furniture)

Hi, my son (16) is in the late stages of his GCSE Deign Technology course and about to submit his final project for evaluation. It needs to be in on Monday!
What he has just discovered (remembered) is that he has to include some professional feedback from a specialist in a relevant discipline. This could be design, manufacturing or even retail, it doesn't matter tbh. just someone with a professional opinion.
The project involves cardboard furniture, a summary of his brief and design is here:

Any comments, feedback, suggestions for improvement most welcome and appreciated.

Thank you.
