I was a bit leery about ordering this mattress after reading the reviews about the chemical smell and all but after hearing others state they had recently received it with no problems I tried it out anyway. I was very pleased with the product. We received it late in the afternoon and unfolded it to find no chemical smell whatsoever and my son was sleeping on it that night. The size is a bit bigger than a standard twin and required me to use the mattress pad I had already bought for it elsewhere and get a twin xl, but my son is 14 and almost 6' tall, so it worked better for us being a bit longer anyway. This had been mentioned in an earlier review and I was actually hoping I would have that same "problem". My son's quote about his experience sleeping on it...."it's like a dream"!
