My most favorite aspect of this mattress is that the mattress is able to be moved easily. If or when you move from one location to the next, you just need to purchase a plastic mattress bag, insert your mattress, and remove the air. Easier than renting a trailer to move this baby around. There is a complaint I have, but it may be due to how I sleep or my lifestyle. I find that I now wake with shoulder pain and that is something that I have never experienced before. I do not sleep on my sides (well, wake up on my sides) but normally sleep on my back. This seemed odd to me as sleeping on my back resulted in pain in my right shoulder. If I do find myself sleeping on my side, pressure is exerted on my left shoulder. Something strange, indeed, but I cannot fully put these peculiar occurrences on the mattress because my work/sleep schedule has changed multiple times since owning the product.
