Honestly If it was manual I'd trust it more with rails to secure the two shelves and a similar folding up system for the bed that were in early apartments.

yeah the fact this is all hydraulics makes it sus as fuck. itd be way safer if it was hand cranked or just slid around from someone pushing it, and def not attached to a ceiling

It doesn't neeeed too! But done with a high degree of quality it would be quite nice. Like I wouldn't do this with any shitty silicon valley product, but like if I knew it had safety features and would last as reliably as my car, then hell yeah I would go for it.

Edit: thinking about this on my way home from work, basically all of this could be achieved without any automation or motors and it would basically be as safe as non moving furniture. So long as you installed enough high quality rails on the ceiling it would be fine.
