We have these for the whole family, kids and parents. Great pillow and we sleep very well now. it is a great option to keep them end to end for the whole breadth of the cot and no one is inconvenienced because they use a standard pillow. The reason we bought that many is because, mixing them with standard pillows side by side can be an issue as these pillows are big and can be a bother for the person who is using the normal pillow. On a lighter note, mixing this with standard pillows creates an automatic 'social distancing' while sleeping :). When all the pillows are of this type, then everyone is happy. Couple of things for consideration.
A) These pillows are large and so for 6 footers, you will keep kicking the edge of the bed at the foot (or) your foot will hang out of the cot. You have lost a significant length of the cot due to the pillow.
B) 7 inches height is great but in where your head rests against the gradient of the pillow (midway of the pillow), I feel the height is less than the normal position we are used to. So tendency is to put our hands under our head to provide the additional height or use a very thin pillow for that height we need for comfort. May be therapeutically that is the wrong thing to do, but practically some additional height (1 to 1.5 inches) at the midway of the gradient may be good.
C) Excellent, soft but firm pillow and very comfortable against the head. We sleep very comfortably.
