After its development by NASA for space craft safety and comfort, Memory Foam was adopted by the medical field for bed restricted patients as it was recognised to improve alignment and circulation in the body due to its unique moulding properties. The Logan & Mason MEMORYCLOUDTM Pillow has a Memory Foam core for pressure relief, and is beautifully complemented by a zippered, 300 thread count 100% cotton japara cover. Fully piped and gusseted for maximum loft, the MEMORYCLOUDTM Pillow cover has been generously filled with plush microfibre and quilted to ensure it maintains its shape. The Logan & Mason MEMORYCLOUDTM Pillow is the ultimate in sleeping comfort, and will have you feeling like you are sleeping on a cloud. The easy care cotton cover is removable and machine washable.
