First impressions:
Arrived in a small enough box that I can carry around. It was vacuum-packed inside. I suggest you cut the bag open inside the bedroom where it's going, to make your life easier. It expanded right away, no smell or anything like that. It is very comfy. I got it for a top bunk bed for my 8-year old (6" thickness). If this one holds its shape, I honestly will consider buying 8 or 10" for myself. The sale price was awesome, couldn't resist.
