Comfort Outlast Cotton Extra Soft

Its heart

At the centre of 508 Comfort Outlast Cotton Extra Soft are Bonnell springs of 2.4 mm, tied into one continuous grid that spreads the body’s weight over the whole surface. Around it runs a support of No 250 foam.

Two identical sides

From the springs outwards the layers repeat the same on both sides: Kevlar 700 g/m², No 900 foam 3 cm thick, G30 non-woven, 630 g/m² polyester and cotton wadding, No 250 roll foam 1 cm thick, 150 g/m² polyester wadding and, on the surface, Outlast 4A fabric. That is why the mattress is double-sided. Turn it over once every six months, so the weight is spread evenly.

The border

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

The feel

With a firmness of 5.5/10 it is medium-firm and, like every Bonnell mattress, orthopedic. It is also hypoallergenic and ventilated, 26/28 cm high. Its cover opens with a zipper and comes off.

The right base

With Bonnell springs, a single spring unit, the 508 does not need a bed frame with dense slats.
