[0002] With the fast pace of life, people often need to take a nap at work or school. Folding beds are simple beds designed using the principle of joints. In order to save space and make things convenient, they can be folded and stored in various ways. They are easy for users to unfold and fold, and convenient for storage in work or school.

[0003] Traditional folding beds can mostly only be folded in the length direction, and their width is relatively large after folding, making it inconvenient for users to store them in the workplace or study. For example, a folding bed frame disclosed in Chinese Utility Model Patent CN202222244925.3 includes two connecting members. A main frame is rotatably installed at each end of the connecting members. A first cross frame is installed between the two connecting members. A second cross frame is installed between the two main frames at one end. The second cross frame is connected to the main frame through a third connector. One of the main frames at one end has a slot and a guide groove inside. An end rod is inserted into the slot. A second connector is installed at one end of the end rod, and a locking head is installed at the other end. A locking slot is opened at the end of the other main frame. The locking head is inserted into the locking slot. A sleeping mat is rolled up on one of the end rods.
