However, to create various designs, manufacturers needed to use multiple pieces connected together with metal bars or other rigid components for their design to work.

The rigid frame bed has been around since the late 19th century. However, only recently have more beds begun to flex. The first design of a flex top king sleep number bed was invented by Petti-Matti Lautakangas in 1988.

How Does A Flex Top King Sleep Number Bed Work?

The main difference between sleep number beds and traditional beds is the type of mattress used. Sleep Number beds are filled with air and have a stretchable outer cover.

This means that these beds can easily change shape to perfectly fit each individual’s body. The air chambers inside the bed will hold this shape.

The mattress is filled with air, which is made immobilized by the outer polyester cover. When you lay on the bed, the layer of polyester stretches around your body and creates pressure under your body to make sure you are perfectly supported, even when you have a “u-section” shape from sleeping on your side or stomach.
