We picked this hot tip up in the Flou Bed thread. If you want a hydraulic lift storage bed and don't want to go the high class route, then this is for you.
Lift & Stor Beds makes a simple, strong platform bed KIT that lifts up for storage. The kit contains hardware, cut lists and all instructions. The kit only costs $160. This kit doesn't include the WOOD (obviously, but we just had to make it clear), but our tipper says "most Manhattan lumber shops will cut all the lumber based on dimensions you give them," which is true. Having the cut lists makes it easy.
In addition, working from a kit allows you to change dimensions. You can raise the height of the bed to fit more inside, add headboards and stain the wood to match your own decor. (Thanks, JWN!)

I can respect the cheap price, but that's the fugliest bed I've ever seen. And resting your mattress on a flat board that doesn't breath can't be good for it.
Eh.
I've had several mattresses striaght over plywood for decades and it seemed to do precisely zero harm in the way of longevity. (Despite mattress sales propaganda)
They "breath" just fine through the top, it seems to me.
I suppose in it might matter if you lived somewhere really humid all year around where water vapour might have a tougher time of disappating, or if you have tonnes of bedding over it.
Does anyone know where one can find these Manhattan lumber shops?
Well the beds look is what you make it....they give you the hardware and plans to build it...your own personal taste can come out.
i have a select comfort air bed that we are building the lift platform for the storage.
if you think about it all a box spring is a BOX with wood slates inside covered with fabric.
It does not harm a mattress to set on the platform...if you have a good mattress- that is where the springs and supports or in my case the air bags air...with the pillow top cover.
I am thankful that I have found a way to utilize storage under the bed...and at a reasonable price....
