A retractable bed is disclosed which can be raised and lowered in a vertical fashion. The retractable bed includes a frame for holding a mattress; and a counterbalance system to raise and lower the bed through vertical displacement. When the bed is in the lowered configuration it will come into contact with the floor thereby permitting a person to sleep on the bed. When the bed is in the raised configuration it will be near the ceiling thereby permitting a person to pass under the bed. The counterbalance system provides a convenient way to take the bed down and to put it away. |
