This is a luxury pocket sprung; hollowfibre pillow. This pillow has a core made up of 56 individual Posturfil springs, which is trademarked technology. This pillow has a FIRM firmness rating, giving excellent support to the head, neck and shoulders. To set a perfect height, comfort and overall support the sprung core is wrapped in supersoft spiral hollowfibre filling (feels like down). Each strand of hollowfibre is perforated allowing moisture to flow away from the head and also allow an easier airflow as you sleep. A high quality 230 thread count 100% cotton fabric has been used for these pillows, which helps maintain the filling and the warmth inside the pillow. The casing is complimented with a fine piped edge. The product is carefully made in the UK.
