We have combined memory foam with individually wrapped pocket springs to create a superior level of comfort. The Dormeo Wellsleep Hybrid mattress is designed to provide sheer luxurious support and pressure relief. Starting with a responsive layer of pocket springs resting on a bottom layer of ecocell foam, then adding an adaptive layer of memory foam at the top of the mattress, which moulds perfectly to your body’s contours providing excellent support and comfort.
Comfort of Memory foam
This pressure relieving material originally designed for NASA, cleverly moulds to every contour of your body, delivering you restful and supportive sleep right through until morning.
Individually Placed Pocket Springs
Springs are individually created and then placed in their own fabric pockets, which allows the springs to move independently of each other. The result? Right support for you and your partner where it’s most needed, regardless of differences in weight.
Breathable Airmesh Sides
For optimum breathability our unique Airmesh sides help move humid air out and fresh air in, enhancing constant air circulation throughout the mattress so you can sleep comfortably at the right temperature.
Non-Slip Base
The base of the Wellsleep Hybrid mattress is made from a unique non-slip material ensuring it stays in position, providing an effortless sleeping environment.
