How might I make a loft bed where the bed height is adjustable?

I want to make a loft type bed for my daughter, with a desk / dressing table underneath.

However, she is still quite young, so I dont want the loft bed too high at night.

I want to be able to move the bed platform up and down to a high 'out of the way' position for use in the day and a low position for sleeping (sort of  'just above the desk top position')

But I obvioulsy need to be able to move the bed up and down on a daily basis, so I need something to achieve this.

I am looking at what mechanisms people might think suitable - tracks with linear actuator or gas struts perhaps? with obviously some sort of locking device.

Any ideas guys?

Gas struts would be a very good method. Much more economical than actuators.

How about treating it as a sideways Murphy bed ? Just pivot it up against the wall over the bed ?

I think you meant over the desk but yea I would go that way and I would add a counter weight to make lifting the bed easier.

Gas struts might be simpler, and they wouldn't need to swing out at the back.

The thing with a bead that goes up and down with gas struts or any other mechanism is it will need guides to keep it stable when in use and when it is going up and down then it will need to be mounted to the ceiling or mounted to the guides.

With a Murphy bed that folds out mounted to the wall you can hide it with a chalk board, and mounted right it does not need to swing out at the back, the desk its self can act as the support when the bead is out.

I was hinging my concept off the wall, but using struts to make it easier to handle.

Ho I see struts instead of a counter weight to flip it up.

A garage door opener might have the lifting capacity to handle it and you could improve on that with block and tackle type pulleys. And once finished you could opperate it all by remote control.

You could use ACME threaded rods and simple motors, think trailer hitch lifts. You could probably get away with two threaded rods with motors and two smooth guide rods. As long as the motors are relatively synced it should be fine.

You could look into a sort of winch/pulley system. Put the winch at the bottom, the ropes run up to pulleys at the top of posts, and then connect to corners of the bed.

Another option along the lines of swinging would be to build a frame that looks like the sort of loft bed you're talking about but bring the bed down to the level you want it. Put the back corners of the bed in pivots and the front free, resting on stops. You could rig some gas pistons, like a car hatch, to assist with pivoting the bed up but that would probably be expensive. A simple pulley would be more cost effective and adding a winch gives you some automation.

Whatever you decide on you need to take safety very seriously (which it seems you are by trying to get the bed lower but it still needs to be said). Any automated system needs redundancy in case of failure and it also needs to be nigh impossible for anyone but you, or another responsible adult, to trigger without your supervision. Take into account things like power outages when you'll need to manually operate the bed and you can't have a power on state holding the bed in place. Remember you're daughter is going to get heavier and you'll still need to be able to hold her weight in a few years, especially if you spend much money building an automated solution.
