Don’t mind the children jumping around. They were so excited about their new mattress. This mattress came in a box, neatly packed.  It fluffed up quickly upon release from plastic wrap. As for comfort, I feel that it isn’t firm enough for heavier adults.... but the children will greatly enjoy it. It gives enough cushion to accommodate weight, but if you’re expecting firmness, this isn’t the mattress for u. Overall, I like it so far for use in children’s room.
