The Joseph Crown Tiara Mattress contains a single layer of high count pocket springs, because we believe that this mattress provides exceptionally responsive bedtime comfort. The support system instantly reacts to changes in sleeping position to maintain maximum head to toe support. The addition of a deep memory foam layer serves to provide a sumptuous sleeping surface. The sides are micro-quilted while the contemporary classic fabric has stretch qualities to maximise the benefit of the memory foam and also to give a really eye-catching appearance. There are flag stitched turning handles on each side of the mattress for easy care and also comes with brass vents that will ensure that the mattress stays healthy and fresh for many years to come.
