Oh, you mean because it's without legs?
I like being near ground, so it perfect for me. Also no worries braking it by throwing yourself in it! (I'm a bit heavy, so it can be a problem)
DIY and fix that shit! It can't take more than 5-10 minutes to get the legs off or just pulling the mattress off and use it alone. It will be long before I go back to the original beds with legs, it's worth it. ^^
/edit
Oh right, if your mattress itself doesn't have springs, it's not worth it
