I did not get gas struts either. I added them myself and here is the challenge: The bed frame is made from thin pressboard. The struts require some ummmffff (its an engineering term) to lift the bed. When you go to close the bed you have to overcome the ummmffff and the result is a torn up bed frame. The second problem is keeping the hatch closed. Because the 29.3 hatch is small there is not a lot of the mattress sitting on the hatch so it will tend to pop open.
Long story short, adding struts also meant reinforcing the hinges and the frame they attach to, and installing several catches to keep the lid shut.
