We live in Manhattan where space is a premium. We are fortunate to have a playroom that also needs to double as a guest room. Our idea was to hide a queen murphy bed behind our IKEA BILLY bookcases.
What’s a murphy bed?
A Murphy bed is also called a wall bed, pull down bed, or fold-down bed, is a bed that is hinged at one end to store vertically against the wall, or inside a closet or cabinet. (Source)

Conventional Murphy beds didn’t quite fit into the space and they are expensive. So a hack seemed in order:

The center bookcases are mounted on a piece of plywood on wheels with the Murphy bed attached to the plywood.
It’s pretty manageable to spin around when the bed is needed.
For the side shelves I used two bookcases to add depth to accommodate the depth of the bed when it is hidden.
I used some old IKEA hardware to keep the center piece from being moved.
Here it is in action:

#1 Storage bed using KALLAX shelving units
We bought an old house with original hardwood flooring from the 40s so we were very concerned about damaging it. The casters on a normal bed frame put a lot of pressure on a small surface and we didn’t want it dented or damaged if things started a rockin …. Plus, a 40’s house has virtually no storage as you only needed 3 pairs of pants back then. See the tutorial.
#2 Store your entire wardrobe in this MALM bed
This is one heck of an IKEA hack. Stefan made a storage bed. Correction: It’s a bed with massive amounts of storage out of 2 MALM bed, 4 MALM chest of drawers, 2 nightstands and 1 headboard. See the tutorial.
