A mattress structure able to adjust elastic support forces comprising:

• a fixed plate, which has a plurality of flexible accommodating holes and a plurality of first flexible members;
• a moving plate, which has a plurality of second flexible members corresponding to the flexible accommodating holes, the moving plate being below the fixed plate and having a distance with the fixed plate for moving;
• and
• a support plate, which is below the moving plate and has an air compressor at the bottom thereof, the air compressor having a plurality of air bags disposed between the support plate and the moving plate and a plurality of tubes connecting the air compressor with the air bags, the moving plate being moved up and down through that the air bags pump gas in order to make the second flexible members go through the flexible accommodating holes and be out of the surface of the fixed plate.
