Most construction grade plywood is rated for a minumum of 75 Pounds per square foot loading (depends on support spacing). For example, 6 ft by 4 ft bed = 24 sq. ft x 75 = 1800 pounds divided by a safety factor of 2, therefore that means that your bed should support at least 900 pounds of uniform load. I don't think you will have a problem. No warranty or guarantees provided however. Worse case if it seems to be taking point loading is to thicken up the plywood.
