If luxury is the objective then the Crown Emerald Mattress most certainly fits that scope. The UK manufactured high count spring system has a deep memory foam layer which moulds around the body to give excellent pressure relief. The high loft mattress and the stunning super soft mattress fabric make this one of the most admired beds in the Crown range and represents extravagant value for money. There are turning handles on each side of the Joseph Crown Emerald Mattress for easy care and brass vents that will ensure that the mattress stays healthy and fresh for many years to come.
