Fixed height bed, 4-section, 3 of which jointed and 1 fixed centrally. Mattress platform made of thermoformed ABS, easy to be removed and cleaned, with round edges and integrated mattress stoppers. Base frame of epoxy-coated steel pipes to be equipped with wheels. The bed intermediate frame of epoxy-coated steel pipes supporting the mattress platform can host either, swing-down, sliding-rail or 4 section safety sides; on both sides of the intermediate frame there is an accessory/drainage-holder metal bar with 2 mobile sliding plastic hooks, each one with a 3 kg capacity. Frame provided with proper housings for patient lifting pole and I.V. poles at the 4 corners. Plastic bumper wheels protect the four corners of the bed. During adjustment, the roto-translating backrest automatically shifts backwards to compensate patient pressure on the mattress: this allows to avoid continuous repositioning of the patient on the bed , to reduce the pressure on the plexus/pelvis areas to enhance breathing and to make the patient posture significantly more comfortable. By roto-translation the backrest shifts 11 cm backwards.
