Maybe, but since they aren't simulating a body, the demonstration is just flashy without proving anything.
It is not necessary for parts to take up the whole rest of the mattress. You may be right that a smaller plate of glass that did not spread over so large an area might put more pressure on the eggs, say a 1 ft by 1 ft by 6 inch object. Or something.

To me, that test demonstrates the ability for the mattress to allow pressure points to sink without increasing the pressure on them, and still provide full support to the raised areas.

Of course, does that actually provide for a more comfortable sleep? I think it would, but I don't know that this mattress actually accomplishes it.

The rest of your post sounds like a commercial. Are you affiliated with this company?
No, I'm just someone with sleep problems who has lamented the problem of finding a comfortable bed on many an occassion. That commercial precisely addresses one major item I've identified for myself.

In order to break an egg you generally have to apply a sharp sudden pressure at one point, such as whacking them against a sharp corner. Eggs are surprisingly sturdy.
If I come across a 300 lb sheet of glass I'll try it out.
I guess you didn't watch the video where they did that test for you and showed the eggs breaking on other mattresses. Or maybe you just think they faked it, one way or the other.

Oh, and while eggs might be surprisingly sturdy, I have managed to break them with my grip, and I'm not exactly popeye. Not a sudden pressure.

The connection with comfortable sleep is maintaining your body in a neutral position and fully supported without pressure points. Lying on your side and having your waist sag curves your spine and gives backaches. Lying on your back with your knees flat is highly uncomfortable as it strains the lower back. Most mattresses do a poor job of solving that problem, despite variations of coil springs, foam, padding, and even air inflation or water inflation.

what if I advertised a car and I spoke about an egg test, where I dropped eggs onto the car seats from the height of the roof of the car without them breaking, and then implied that my car was safer because of that?
Do you provide a theoretical description of how it provides safety? Because that website has a good description of how that test demonstrates the conflicting needs of a soft giving upper layer to allow the low points to sink in without too much pressure but simultaneously a stiff upper layer to support the high points.

Your shoulder and hips need to sink in while your ribs and waist get supported.
