Cocoon is a portable safe space for convulsive seizures. For many people, convulsive seizures are 'normal', but there are necessary steps to ensure safety. Cocoon addresses all convulsive seizure first-aid requirements - anywhere, anytime.


Cocoon was the 2019 US National Winner of the James Dyson Award, placing in the International Top 20.

Background Information

Epilepsy is a common condition that has simple first aid steps - however, they are not well-known and require some items which aren't always on hand. This is one of the main reasons for higher risk of death. 

Storyboard of Problem



Having a seizure in a 

dangerous location 

Case 1: Improper Care

-   Putting choking

    hazard in mouth

-  Restraining

Case 2: Panic Call to Ambulance 

-   Hospital is expensive 

    and often unnecessary

Worst Case: Too Scared to Leave Home

Gap in the Market

Two types of products come close to Cocoon: seizure first aid information and seizure head protection. However, there are no products that do both. The continuous use of headgear is impractical, and seizure first aid information doesn’t provide physical protection. Cocoon is designed to fit this gap.  

Survey Responses

Key sketches and prototypes

A product that consists of an anti-suffocation pillow and first aid instructions. This improves patient safety by: informing by-standers on how to act and providing the necessary physical requirements (cushioning and an open airway).

How to Use


Lay down

Features: Head Protection

Instructions inform bystanders

Mesh secures head on side

Contoured pillow keeps airway open

Anti-suffocation pillow 

First aid mandates that the epileptic cushions their head and lies on their side to keep their airways open. Cocoon is an anti-suffocation pillow shaped to encourage the user to remain lying on their side. 

Features: Portable

Cocoon is portable. It is designed to roll into a pouch and function as a pill case when not in use, and pops open in 5 seconds when needed. 

Head Protection

Blue is a calming color, which is an essential mental state to be in when dealing with emergencies. Athletic wear inspired the form to ensure the product remained gender-neutral and empowering for the user, rather than a reminder of a disability.
