Can this be used for a king size mattress

I wouldn't know, I used it for a full size

where are the instructions for these ?

Had to go online to figure them out, THEN had to have a handyman do it, THEN they weren't strong enough to hold up my 5th-wheel bed to access storage underneath. Much waste of time and money.

I purchased one of these but need stronger pneumatics, as the bed is heavier than expected. Can I purchase just a heavier piston? If so, where?

The bed that I built is quite heavy and it supports me for my needs. What I did add was a cap so that it does not go down alone. You can search for these more consistently as these in particular are good.

Is the 30 kg rating the capacity of each strut or the pair of struts together?

It came as a pair. However, I would not recommend these. They arrived with no instructions and would not install properly on my RV queen bed. I ended up with struts on each side instead.
