Think about it… Online mattresses are compressed down to 20% of their original size to fit in a box. You just purchased 20% materials and 80% air/nothing.
You see… in making foam, liquids mix together and start to rise. The faster it rises the more air is sucked in and less material is used. Quality foam is made in a vacuum setting, forcing it to rise slower so there is more material and less air. Quality foam can’t be compressed into such a small box. Mattress coils are no different. Quality strength wire will not compress into these smaller boxes without damage to its integrity.
Consider this fact… Every major mattress brand has machines to compress mattresses in a box...but only their lower quality mattresses are done that way.
So, don’t buy the lie… When you see online mattresses saying their mattress is ½ the price of x name brand, they are not comparing quality to quality.
