This is very sturdy and I used it on a platform bed that had slats that resembled balsa wood.  The rods in it have not bent in the least and my son is 6'2" and around 200 pounds. I tried it and could feel the rods through the memory foam mattress but my son says that he can't.  I would suggest using a mattress that wasn't entirely memory foam or that is thicker than 8 inches. Well worth the price paid.
