- jacquesm 9y agoIf you look at the video linked elsewhere you'll see they use a giant press to compress the mattress between two sheets of foil and then they heat seal the ends. After releasing the press it all stays nicely flat because of the same reason: there is no air in the mattress and no way for air to get into the mattress. I figure they do it that way because it is much faster than just letting the vacuum do the work which for a production facility is a must. But when you have a small budget and more time then using the vacuum directly is the best way to go. There is an interesting branch of manufacturing related to this trick: https://en.wikipedia.org/wiki/Vacuum_forming https://en.wikipedia.org/wiki/Vacuum_forming
