Great buy!

The packaging was great. Super easy to open and use. It fluffed up to full capacity in about 24 hours. It's firm but nice and soft at the same time. My son absolutely loves it and says his bed is ten times more comfortable to sleep on now. He's had it for a few weeks now, so I can't speak to long term durability but it seems to be great quality.
