Molift Smart 150 mobile hoist that is “Light, foldable and transportable without tools” however it cannot be done under the bed if the bed is not raised so you may need to look at bed blocks/elephant feet. One wheelchair user says: For the last 6 years, I’ve had a portable MoLift Smart that I’ve taken everywhere! It’s been on around 70 flights, one cruise, one train ride and it has lifted my backside in about 20 countries. Its been thrown around and given rough treatment by damn baggage handlers all around the world, but the thing still works fine! It’s the only decent travel / portable hoist I’ve ever found.
