An electric bed with an adjustable bed length, containing an upper head bed frame, an upper foot bed frame, a lower bed frame, and a plurality of bedboards. Wherein at least one of the plurality of bedboards is pivotable relative to the lower bed frame. Wherein either of the upper head bed frame and the upper foot bed frame is fixed/immobile relative to the lower bed frame while the other contains a moving component which moves back and forth relative to the lower bed frame between a rest position and an extension position. Wherein the at least pivotable bedboard keeps horizontal and the upper head bed frame is away from the upper foot bed frame by Distance 1 when the moving component is located at the rest position, while the at least one pivotable bedboard pivots and there is Distance 2 between the upper head bed frame and the upper foot bed frame when the moving part is located at the extension position. Wherein Distance 2 is longer than Distance 1. The bed length is adjusted in the above-mentioned way to overcome the defect in the traditional electric bed where the bed length is shortened after the posture is changed, causing part of the matress to have no support basis. Further, the electric bed works reliably with an always pleasing appearance and can be conveniently assembled with a low risk of injury to a user's hand.

A three-dimensional net-like structure is provided that has a soft cushioning property and less variations of hardness and is less expensive.

The three-dimensional net-like structure is made from a thermoplastic resin including a mixture of a polypropylene copolymer (a) and a polypropylene copolymer (b) and has a spring structure formed by bonding continuous filaments partly in random in loops. The polypropylene copolymer (a) has a flexural modulus that is different from a flexural modulus of the polypropylene copolymer (b).

A medical supporting fixing device having a yaw angle fine adjustment plate (6) and/or a tilt angle fine adjustment plate (8) interposed between a stage (2) and a supporting fixing means (4) for supporting and fixing a predetermined part of a human body. The yaw angle fine adjustment plate (6) and/or the tilt angle fine adjustment plate (8) are mounted so as to be rotatable over a predetermined angular range about required rotation center axes (22, 48). A yaw angle fine adjustment plate drive mechanism (16) and/or a tilt angle fine adjustment plate drive mechanism (54) including input members (28, 72) and transmission means (36, 38, 42, 74, 80, 82, 84, 86) are disposed with respect to the yaw angle fine adjustment plate (6) and/or the tilt angle fine adjustment plate (8).

A hospital bed includes a sleep deck having an upper portion, a middle portion, and a lower portion each defining a support surface and an underbody that defines a notch. An opening is defined by and extends through the upper portion. A space is defined between the upper portion and the middle portion. A mattress is disposed on the sleep deck. An outer mattress shell encases the mattress and includes a fold defined by a weld. A mattress retention assembly is coupled to the outer mattress shell. The mattress retention assembly includes at least one of a first magnet and a second magnet selectively coupling the mattress to the sleep deck, a portion of the mattress retention assembly extends between the outer mattress shell and the sleep deck, an affixing member disposed on the outer mattress shell, and a retention ridge extending through the sleep deck.
