Looks like I can get square tubing [http://www.metalsdepot.com/ here], enough for under the bed, for about $60 including shipping. I think 1/2" steel square tubing is strong enough (should be less than 0.1" deflection). 3 beams going the long way at 5 beams the short way.

	The shelves will be desk style. So the shelves always stay parallel to the ground. When the bed is up, they're just shelves, when the bed is down, they are safely stowed below the bed.		The shelves will be desk style. So the shelves always stay parallel to the ground. When the bed is up, they're just shelves, when the bed is down, they are safely stowed below the bed.

			I need to decide if the bed will go all the way back, or if I'll reserve some space for storage (or in between). Going all the way back leaves more room when the bed is down, but cuts a whole arc out of storage.

	Have a matching action that swings out two poles that support a canopy. Make it out of a light fabric that is highly innsulative. That should help trap the heat while we are sleeping.

			=== Electrical ===
			Outlets, USB out. Possibly lights, possibly speakers.

			I would like a motor to raise and lower the bed, probably needs a screw drive. I'll need limit switches. I'd also like to make strain sensor out of a spring and a limit switch so that if someone is on the bed, the motor won't even try to lift it; set it to the weight of the bed + 50lbs on the shelf.

			=== Tray ===
			Very cool would be small desk/trays that would fold down. Enough to hold a laptop.

			=== Cushioned Backs ===
			When the bed is down, the headboard would be slightly angled and cushioned like the back of a couch for comfy sitting.

			=== Auto-Stabilizers ===
			The non-auto version is two straps to hold the sheets in place. But I'm thinking about two pieces that flip to hold the sheets in place. They would be connected to the pulley system, so no additional motors are required. When the bed is down, they would lie around the bed, above the head and below the foot - they would form the perimeter.

			== Linkage ==
			The shelf/leg linkage is actually pretty easy. Image each shelf as a triangle (back, bottom and hypotenuse). The mattress clearly has a hinge. The linkage is connected to another hinge 45° forward and down. The linkage connects somewhere along the hypotenuse (where doesn't matter, but it has to be the same on all shelves.

	~~Cabinet for~~ bed ~~with convinces~~.		When the bed is up, there are three layers; closest to the wall is a storage area, then the mattress, then the shelves.

	I ~~like~~ the fold down desk. ~~Very simple, just supported with rope on either end. Important that there be a latch!~~		The storage area is shelves and an electronics panel. The panel will have lights, power and usb and speakers. There will be a space to store pillows when the bed is up. And above that shelves for other storage. I also want a trash can under the electronics panel. It would also be nice if there was a fold down desk in here.

	~~I want light~~ and ~~shelf space near the head of the bed. Also a shelf to hold the pillows during the day~~, but ~~form a little shelf for charging gadgets~~, ~~holding gadgets~~ and ~~such at night~~.		The mattress needs to go up and down easily, but it may not be bad to begin with, and if it is, I should be able to add some springs or counter weights. Lauren requests that there be a latch.

	~~I would also like a fold~~ down ~~desk in~~ the bed ~~for a computer or breakfast. More shelving space could be located behind this (perhaps for sheets)~~.		The shelves will be desk style. So the shelves always stay parallel to the ground. When the bed is up, they're just shelves, when the bed is down, they are safely stowed below the bed.

	Under the mattress, there should be a few springs arranged such that there is no tension on them when the bed is up and maximum tension when it is down, this should significantly reduce the force necessary to raise the bed as well as prevent it from slamming into the ground.		== Requirements ==

	~~Build in a set of speakers (maybe the Monsoons) for when we have a laptop in bed or Lauren wants to listen to music.~~
