One Mattress. Three Firmness Levels.

The ecosa King Single has an adjustable firmness feature. It caters to change-of-mind – especially for teens starting to think for themselves! An adjustable mattress lets them choose the firmness and comfort level they want. They can even keep experimenting with the layers!

For sleepers who like being 'hugged', the G-7 Memory Foam layer lets you sink a little while still providing optimum stability for your back.

Great for sleepers with chronic back pain, the ECO-tex layer contours to the body's shape and gives it a little bounce back.

Engineered for spine alignment, the ergonomic foam layer is springy yet dense enough to keep the back comfortable stable through the night.
