I ordered this for my husband for Christmas. I was happy that it didn't have a 'guaranteed delivery by Christmas' guarantee but I got it very fast. It didn't take long to expand and we've really enjoyed it. I don't know why but I was thinking that the cover just went around the foam but it is a full on fitted sheet that feels amazing! Someone had complained in their review about it not having the egg crate on one side but ours did! I would definitely recommend this to someone else. My husband is normally a monster in the morning and after his first sleep on it he woke up and started tickling me and making jokes haha!
