Has anyone heard of Mattress Wrapping to prevent SIDS

We have ds mattress wrapped.
How to cover your mattress with BabeSafe
It's not bunnings plastic and it has vents thru it to help the mattress breath underneith.
Ds started sleeping on his stomach at 4 months which freaked me out, and wrapping his mattress wasn't causing any harm so we just did it for peice of mind- even I it was fake it was either that or neither of us sleeping.
It's basically a giant plastic pillow case to suit the size of your mattress (you order to size) and you just pop the mattress inside.

ETA there is 0 suffocation risk. Probably the same amount if your baby was to face plant on a normal mattress. The "wrap" is extremely firmly placed over the mattress (they're ordered to suit the size of YOUR mattress) and then sealed at one end. No lose bits anywhere.
There is also some info on using only natural fibers for bedding such as cotton to prevent overheating of baby. Personally I always think if it doesn't cause harm, then it doesn't cause any harm.
