The website says the new model uses hydraulics, actually it looks like a gas ram, like you'd find holding up a car hood or a hatchback.
An electric-powered linear actuator could work, but they get expensive for the long ones.
The part that I don't understand is the gas spring. Are you envisioning a manual lock that will lock the bed at the top and bottom, and the gas shocks are intended to make it easier to manually raise and lower?
My thought would be similar to what /u/TW_2 suggested. If it were me, I would be looking at linear actuators. The longest ones I found in a quick google search have an 18" stroke length so I'm not sure if that gives you enough travel.
EDIT: I found this actuator with a stroke length of 30". This actuator will move 225lb, so if you're using four of them they should be enough to carry a bed and a few people.
