I was looking for a mattress for my son after his air mattress developed an uncomfortable bubble. This one was affordable, so we decided to give it a try. It arrived fairly quickly, and it expanded to full size within a day of being unpacked. He says it was very comfortable, and being a twin XL it was a good size since he is 6' 4" and 230 pounds. I'm chemically sensitive, but the mattress, which smelled like plastic, aired out within a few days and no longer has that odor. Overall, the price was excellent for the mattresses comfort, and the size was perfect. I would recommend this mattress for larger people looking for affordable comfort.
