Triangular design elevates the upper torso to treat sleep related conditions Helps acid reflux, snoring, heartburn, sleep apnea, GERD/GORD, back pain, respiratory issues and more (NHS Recommended) 3 methods of use – under pillow for upper body elevation, upright for back support, and leg elevation Constructed from a durable and high-density foam that holds its shape over time Includes a fitted, washable cover Hand made in Devon, UK – backed by a 2-year guarantee Dimensions (W x L x H): Selected Width x 30" (76cm) x 6" (15.2cm) The Putnams Bed Wedge is recommended by the NHS to help relieve sleep related conditions such as acid reflux, snoring, heartburn, sleep apnea, GERD/GORD, back pain, hiatus hernia and more. It has the ideal height of approximately 15cm (NHS recommends 10-20cm high) and features a triangular design which allows it to be used in three different ways: Upper Torso Elevation When this bed wedge is placed beneath a pillow, it elevates your upper torso which is especially beneficial if you suffer from acid reflux, heartburn, respiratory issues, hiatus hernia, rhinitis, glaucoma and vertigo. It also improves your posture & spine alignment which in turn, relieves back pain. Back Support Place the bed wedge upright against your bed’s headboard to use it as a back support. This makes it perfectly comfortable for reading and watching TV. Leg Elevation Place the bed wedge beneath to elevate and support your legs, knees and feet. This increases blood circulation and can help alleviate discomfort from varicose veins, swollen ankles, arthritis, phlebitis, oedema and other leg related conditions. Sleep Better Tonight Unlike ordinary bed wedges, this one by Putnams is constructed from durable and high-density foam that holds its shape over time without flattening. When you lie flat, gravity increases pressure on the spine and airways, and leads to a rise in stomach acid. This results in sleep disruption and poorer quality of life. Sleeping on a gentle incline helps to keep your airways open, so you wake up feeling rested and full of energy, instead of tired and groggy. The Putnams Bed Wedge is also available with a pressure relieving memory foam top or a cooling, anti-microbial latex top.
