love the beds for my 3 babies... i rest easier knowing they r resting on these mattresses... that being said , they r kinda flimsy to carry and move around, i guess less toxic product inside to keep as sturdy, thus can feel the springs from the top/bottom edges of mattress... i was worried kids could feel when lying on it but once down and in place it's good, worth it for me as i know they are not sleeping on anything toxic
