Opera beds. Luxurious and supremely comfortable, the Emporia truly is the Emperor of all adjustable mattresses. 1500 individual pocket springs laid by hand are enveloped in several layers of luxurious natural fillings including Dartmoor sheep's wool, hand-teased horsetail and fine cottons making for an ultra deep and sumptuously comfortable mattress. Springs and materials are specially laid to ensure flexibility with an Opera adjustable bed base. Your Emporia is hand made to order and you can choose either a soft, medium or firm feel.
