This mattress features a supportive core of orthopaedic springs and deep fibre fillings. Each spring inside this mattress is an hour glass shape, having the springs shaped this way will give your back the ultimate support and relieve aches and pains which result in you feeling relaxed and refreshed. This mattress is also deeply tufted to give added comfort and is also filled with additional fibre fillings – including rebound foam – that are not only firmer but also breathable. The Backcare Supreme is also covered in a stylishly soft damask. This is the firmest mattress in the whole Backcare collection.
