Mattress test manikin-lateral position

A system for measuring spinal and/or skeletal angles of a manikin in a lateral position, the system comprising:

• a support surface, the support surface adjustable in at least a vertical axis;
• a manikin, the manikin comprising one or more articulating joints, including articulating hip joints that hinge sideways and rotates, enabling a knee of the manikin to rest on the support surface when the manikin is in a lateral position;
• a spinal and/or skeletal profile defining a manikin profile;
• a suspension frame, the suspension frame suspending the manikin;
• and
• one or more measuring devices connected to the manikin at one or more measuring points;
• wherein
• the manikin comprises a suspended configuration when suspended by the suspension frame;
• the manikin comprises a supported configuration when supported by the support surface;
• the one or more measuring devices measures differences in the spinal or skeletal angles of the manikin profile between the suspended configuration and the supported configuration;
• and
• the one or more articulating joints are adjustable in resistance or to limit the angle of articulation.
