parent falls

Project Mockup Conclusions

n What we learned: ¨ Must be stable and able to collapse ¨ Attachment arms must be rigid during use ¨ Importance of safety in every element of design

n What’s next: ¨ Refine folding; locking mechanisms for rigidity ¨ Develop sunshades and coverings ¨ Research additional features

Come see us in Pappalardo!
