Comfort Bio Thermo Cotton Cool Max Hyper Soft Extra Memory Gel Mini Bonnell

Its heart

At the centre of 557 Comfort Bio Thermo Cotton Cool Max Hyper Soft Extra Memory Gel Mini Bonnell are Mini Bonnell springs of 2 mm with a frame, tied into one continuous grid that spreads the body’s weight over the whole surface. Around it runs a support of No 300 Extra foam.

Two sides

The mattress is double-sided, with two different sides. From the springs outwards, one side has Kevlar 700 g/m², 5 cm of memory gel, G50 non-woven, No 2500 roll foam 4 cm thick, 350 g/m² cotton wadding and, on the surface, Bio Thermo 9A fabric; the other has Kevlar 700 g/m², 5 cm of memory gel, G50 non-woven, No 2500 roll foam 4 cm thick, 150 g/m² polyester wadding and, on the surface, Cool Max fabric. Turn it over once every six months, so the weight is spread evenly.

The Cool Max side

Cool Max is a fabric that helps draw moisture away from the skin so it can evaporate quickly. Instead of holding sweat, it lets air pass freely, which helps the body cool itself naturally. Since you turn it over every six months, keep the Cool Max side on top in the warm months.

The border

All around, the Dark Grey Velute border has handles and vents, so the mattress can breathe.

The feel

With a firmness of 4/10 it is medium-soft and, like every Bonnell mattress, orthopedic. It is also hypoallergenic and ventilated, 30/34 cm high. Its cover opens with a zipper and comes off.

The right base

With Mini Bonnell springs, a single spring unit, the 557 does not need a bed frame with dense slats.
