Well I used to tell my WPs that if I punched them til they fell over...if they would get head injuries from landing in the bed...it wasn't deep enough.

Pointless, unless your stable drains steeply. Much better to use shavings to absorb the wee on the surface to stop your horse mopping it up with his body or rugs
in a normal 12 x 12 box i would start with about 3/4 bales, deep banks around the outside and approx 1half ft deep. If you give horses a choice of a nice thick comfy bed or a thin one, they will always go and lie in the thick one.
Ive always tested to see if a straw bed is deep enough by letting the mucking out fork progs drop to the floor, if you hear concrete, its too shallow, it should only hit bedding.
I was always told that if you drop the pitch fork into the bed and you hear a clang then it's not deep enough. Although thinking about it, that may not work so well with rubber matting?!
I do the pitch fork thing aswell. Drop it vertically into the bed from about a foot above the bed. If you hear concrete its too shallow.
However I do it thinker for a bigger horse, I find that if I only do it just about deep enough for Baron then when he gets up from lying down he moves the straw to reveal concrete. I give him a really think bed to avoid this.
I was always told to do the fork test as well .... if I use my old (faithfull 15 year old) fork I get the right result .... however if I use my new(er) (7 years old and not used much) fork then I tend to get the twank where it hits the concrete and I must admit my beds are very generous
.. Just put rubber matting down now, as an under/no slip surface and therefore all I get is a thud now!
