Hi shangkan,
Unfortunately the link doesn’t provide any information about the quality or durability of the materials in your mattress so I can’t make any meaningful comments about it without knowing the information in this article.
I can’t see what is under the fiberboard or how it is supported or whether your bedframe has good center support to the floor but it would “probably” be suitable in terms of supporting the mattress. Having said that … a solid surface doesn’t allow any airflow under the mattress so there can be some additional risk in terms of moisture retention or the risk of developing mold or mildew but if there aren’t any other risk factors then it would probably be fine (see post #10 here).
