Hi, I had the same problem so I bought a lightweight pulley , attach one end to the bed frame where it lifts up ie seat back when in the upright position, and the other end to the frame of the pop top roof if you have one or the passenger grab handle. I bought this Mannesmann Rope Hoist <> BGS Kraftmann 180 KG Winch Puller 20 Meter GS CE TUV 4003315712930 | eBay but there are others available. What a difference, easy to pull bed up and aids lowering.
