Gas spring question

[Carolina_coast99]

Hello,
I'm trying to decide what type of gas spring I need.
They (2) springs will assist in "opening" the top part of my bed housing. Underneath will be storage area.
It will be a king mattress resting on a 3/4" plywood, 2x4" framing, with a piano hinge attached along the long edge of the mattress board. So, I will be raising the bed longways on the hinge with assistance from the springs. [A spring will be at the head and one at the foot of the bed]

I'm not sure:
What length (extended and compressed)?
What extension force...?
I attached what I am thinking I may need...

Not sure this is the full location for what I want but the part number is: 4138T58

Help is appreciated!
