Structure de canapé-lit en métal avec lattes en métal lourd Castor

I unfortunately am not very happy with this purchase because it is not holding up well. I use it only occasionally but the metal is bending more and more evertime I let my grandchildren sleep on it and these are not heavy children and they are only 10 and 12 not even teens. This includes the bars that hold the trundle bed mattress as well so I know the entire thing is just shoddy. I know I will have to by another one soon but it was not in my budget being on a fixed income.
