Linear Actuators (for mezzanine bed)

The room where we are building the "Tiny House" is relatively small in terms of surface area. If we were to have a double bed at ground-level it would occupy 50% of the floor space and not leave much space for a wardrobe and movement.

Thankfully the ceiling is quite heigh at 2.8m ... 👍 so my plan is to build a mezzanine bed that makes the most of the height we have available.

IKEA has a "Loft Bed" called STORÅ which is reasonably priced at $299

Here's what it looks like in-use:

It looks "OK" in pictures but when you look at it in-person it's not very sturdy ... This reviewer summarises my feelings on the bed quite well:

I would love to have a "bedUp" https://www.bedup.fr/produit/bedup-cocoon-lit-au-plafond because the design is amaze ... but sadly, the price starts at €2.5k (w/out shipping or installation!)

Watch the video demo to see how slick the mechanism is: https://youtu.be/wnj4w4dlWMs

I think we can achieve a similar effect for €500 (including all materials). My plan is to use linear actuators to raise/lower the bed with the touch of a button.

I'm considering using 1000mm actuators for this application. These are the two most reasonably priced suppliers on AliExpress:

The reason for using AliExpress instead of Alibaba (the main site) is quantity/volume. e.g: https://www.alibaba.com/product-detail/linear-actuator-1000mm_62039851382.html

The price per unit is much cheaper but then the shipping fees are silly. 😞

I have previously done a bunch of research into linear actuators for https://github.com/nelsonic/standing-desk/issues/7 We probably only need two actuators (in opposing corners) to raise and lower the bed, but I intend to use four for redundancy.
