Comparison chart of research results and design strategy

Research results	Design strategy
Cradle pillow is not preferred.	Eliminate the design factor “b.”
Cervical pillow is more comfortable for the neck.	Retain the design factor “c” to provide neck comfort.
Design factor “a” is an important factor for height comfort.	Retain the design factor “a” to provide height comfort.
The more height a pillow has, the higher the comfort level.	Increase the height to 13.2 mm 22.25 − 20.06 = 2.19 mm (difference in the height of pillow no. 4 and no. 5) 11 (original design) + 2.19 = 13.19 = 13.2
Pillow no. 4 is the most satisfactory.	Incorporate the design factor of pillow no. 4 (“a”+ “c”+“d”).
Pillow without design factor “b” and that provides cervical support will have more comfort.	Eliminate the design factor “b” and retain the design factor “c.”
