I love this mattress I bought it for the top bunk of my girls bunk bed. I got it via UPS and it was rolled up into a box whenever I unrolled it the mattress immediately formed to normal size. It didn't have any oder.... my Serta for my bed and my sons had a weird scent when we first bought them. This mattress had aloe vera written all over it so I am guessing it was made with aloe vera inside. I put the mattress on the top bunk before we went out tonight and when I got home and my youngest daughter crawled into bed she immediately fell asleep, that's got to be a great sign. The mattress is actually nicer in person from the picture it looked really boxy and foamy. In person it looks like a normal twin mattress and i very firm and sturdy! I was looking at a cheaper bunk bed mattress but I am glad I went with this one the value is great!
