Sleep Coach Hybrid has an extra foam layer designed with the Euro Top style. The extra sponge is levelled as equally as the height of the mattress edges, creating a homogeneous appearance. Lifting the sponge height boosts the pleasure of your rest. The sponge layer, partially separated from the springs, gives a softer surface feeling due to its thick sponge. This mattress offers you both the durability of the spring and the ease of the thick foam layer.
