Mattresses are okay. They were folded in the box, and have big dents in the material, and one mattress has been out of the box since yesterday, and the creases haven’t let up. Will probably have to put a board under them to give more support, as the mattress is super soft.  I think they might be okay for my 3 and 7 year old, but my 8 yr old would probably be too heavy. I don’t think we’ll get a ton of use out of the mattresses. Which is a shame. I ordered two of them, and they were not shipped at the same time, and came a week after I had ordered the bunk bed. I don’t think I will ever order mattresses like these again. Bottom line is only use these for small children.
