Anyone here using a ceiling-mounted lift bed in a small studio?

I’m in a 278 sq ft studio n the bed is the one thing I can’t seem to work around. No matter how I arrange the room, it ends up blocking the only useful floor space. I’ve been seriously considering a ceiling-mounted lift bed that raises straight up rather than folding into a wall. The idea sounds perfect on paper. But I’m having trouble finding real experiences from people who actually live with one in a small home. My building has 1970s concrete ceilings, which is where most of my questions come from. Almost every guide I’ve found assumes wood joists or full renovation access, neither of which applies to me. I’m not trying to tear anything apart; I just want something safe that won’t get me in trouble with the landlord. I’ve checked marketplaces like IKEA, Wayfair, Home Depot, Amazon, and even Alibaba to compare hardware options. But most listings don’t explain how these systems hold up with daily use or how they attach securely to concrete. If you’ve installed a ceiling-mounted bed in a small apartment. Especially with concrete ceilings, how did you secure it, and did it actually improve the room enough to justify the effort? Would you do it again?
