Wondersheet 2 x Long Single Fitted Sheets. Please Note: Pillowcase is NOT included. The ‘Wonder Sheet’ is an effective therapeutic tool because it can make your mobility in bed so much easier. The satin panel, which is 90cm long, sits under your shoulders, back and hips and allows you to slide your hips over more easily without having to lift them. It’s also particularly helpful when getting in and out of bed because you can pivot on your hips without worrying about the friction from normal cotton sheets. This unique design creatively combines ‘Glossy Charmeuse’ satin and a 50/50 blend cotton/polyester fabric which is beautiful to sleep on while being very durable.
