The Seoul is a medium/firm tension mattress by Sweet Dreams that combines their exclusive Miracoil® spring system with body moulding memory foam. Miracoil® is a continuous spring system that limits ‘roll together‘ by providing individual support so, like Hippo and Duck, you can sleep undisturbed no matter how much your partner tosses and turns. The mattress has also been divided into three distinct zones that relieve pressure on susceptible joints like your shoulders, hips and knees. The upper layer of memory foam works by embracing your body to prevent pressure points, improve circulation and restrict the amount of energy you expend in your sleep, meaning you wake up feeling energised and refreshed. The mattress has also been covered with Purotex®, a 100% natural treatment approved by Allergy UK, which defends against mould and household dust mites to keep your mattress feeling hygienically clean.
