"This is an extra filled side and back sleeper emperor size luxury white duck feather and down pillow measuring at 50cm x 100cm (20"" x 40""). To set a perfect balance of weight, extra support, luxury and loft these pillows are filled with 85% white duck feather and 15% white duck down. The highest quality duck down and small length feathers have been used offering greater comfort and luxury. These pillows are generously filled and weigh approximately 2000 grams each, so will give you the extra support and comfort which usually is not available with natural pillows. This makes an ideal pillow for a back and side sleeper. The filling has been washed, sterilised and steam purified to the European Down & Feather Association's highest standards making them anti-dust mite & hypo allergenic. The fabric used on these pillows is 230 thread count high quality down-proof 100% combed cotton, which helps keep the filling trapped and gives a silk smooth feel. The pillows are complemented with a fine double stitch edging and piped trim giving it a perfect finish. Machine Washable at 40c."
