Patient support means comprise a net for use with a net bed having rotary shafts on to which the ends of the net are wound, so that in use the patient is supported on the net which is slung between the shafts. The net is of knitted form and manufactured from a heat-settable thermoplastics material which is heat set to provide satisfactory memory such that it does not take a substantially permanent set under normal patient loading. The knitted material of the net has a lengthwise extensibility of between 17% and 35%, a widthwise extensibility of between 4% and 12% and a ratio of lengthwise to widthwise extensibilities of between 3 and 6.
