Before the idea of interchangeable parts came along, everything was made by a person somewhere in a workshop. Everything we use can be made by someone, somewhere, on their own, as long as they can buy the materials, have the spare time, and are happy with a great deal of trial and error. Here’s more from MOTHERBOARD:
Focusing on the costs is missing the point, building your own mattress is about definitively knowing what you’re sleeping on. According to the_leviathan711, a mattress is simple. It’s made of a soft comfort layer that’s between 2 and 4 inches thick and a firm support layer between 4 and 8 inches thick. Put one layer on top of another and wrap it all in a cover that fits tight and you’ve got a mattress. Those are the basics, but there’s so much more to the world of DIY mattresses.
“That doesn’t mean all mattresses are only two layers,” they said in their post. “A comfort layer could include two different components—like a layer of soft latex and memory foam for example. Similarly, a support layer might also contain multiple components—like latex of two different firmness levels. A mattress might also contain a transition layer that provides a bridge between the soft and firm. How you decide to construct your mattress is up to you—but at the most basic you need something that’s going to be firm enough to support your weight and soft enough to provide pressure relief in your sleeping position.”
