silent - no springs

Adaptive foam 2.5cm of new generation, adaptive foam that’s springy, hypoallergenic, cool and comfy to sleep on. Like 100% latex, but better.

Responsive Memory Foam 5cm of high density, pressure relieving foam that moulds to support every part of your body. It's an all over hug.

Transition foam 7.5cm of transition foam smoothes out movement and spreads your weight evenly. Your sleeping partner won’t even know you’re there.

Durable base foam 10cm of firm foundation that provides consistent, night after night support to the comfort layers above.

Removeable quilted outer cover The soft, breathable cover helps move heat away from your body so you stay cool. But it’s quilted, so you also stay supremely comfortable.

Inner zip removeable jersey An under layer that ensures Mio looks beautiful, even with the mattress cover removed.

the right kind of firm

Whether you’re 20 kilos or 200, your Mio mattress is made from responsive materials that make sure it always feels firm without ever feeling too firm.

Sinking into bed sounds wonderful, but you don’t want to drown in it. Mio contours to your body while providing just the right amount of springiness.

the perfect amount of cool
