Help with a Caldwell rest

[Wapiti]

Hi all,
Any of you been to a gunshop lately and been able to take a look at one of these things?

The question I have is, they look like hard plastic, but that wouldn't work at all... Surely they are semi-soft so the rifle doesn't jump off them when you fire?

I have used some foam block rests before, got sucked in to buying SmartRest MaxBoxes that also are supposed to magnet onto themselves and to doors, but for our use are just a gimmick and some cockatoos got to them and chewed them to bits anyway. That's what was left after the sun crumbled them.
And they don't have a rear rest either.

This thing, if it's soft, would be just the thing for toting to the hay yard and shooting at targets over a soft rest for a bit of practice. Sitting on top of big wrapped bales. Just for fun, I know they won't replace a bipod or a benchrest for steadyness.

Anyone had a chance to know if they are hard or soft plastic?

Be nice to replace the dead old one. It was never that good anyway, wobbly thing.
But only replace it for a light rest that I can use for fun around the house yards, not on a vehicle.

The innertube strip around the "Maxbox" was an attempt to try and keep in on the (extra cost) U-shaped foam thing that you sat on your door with the window down... the "new improved nuclear magnets" did not keep in on in a fit.
They aren't made to a dimension that fits Cruiser doors anyway, maybe they were designed by a Triton owner.
An example of someone having a great idea, but either not having the skills to get it right for what you tell everyone it does, or see profit more important than performance.
