Hi elapid,
It would also be suitable for your mattress and it would probably be stronger and have a greater weight capacity than an Ikea bedframe and have the advantage of storage space underneath as well but since both would be suitable it will really come down to which one you would prefer to have in your bedroom.
There are some comments, pictures, and feedback about the Genius platform bedframe in this topic and some general comments about these types of wire grid platform support systems in post #10 here.
