The wedge is made of the original VISmemo™ memory foam. It keeps the lower limbs in the slightly raised position, which improves the blood circulation and reducesthe risk of swollen ankles. It can be used as a support during the compression therapy and the anti-bedsoretreatment. It is recommended to use the wedge at night because it helps the blood to flow from the legs to the heartwhich reduces the lower extremity circumference and as a result it is much easier to put the compressionstockings on in the morning. The excellent anatomical shape of the wedge prevents the lower limbs deformation. It keeps the pelvis slightly tilted which decreases the pressure and reduces the pain of the lower partsof the spine. The CertiPur Certificate means that the foam is strictly controlled in terms of the amount of chemicals,the method of production and the safety of usage. The certificate guarantees that the product is free of heavymetals, phthalates, allergic and carcinogenic substances.
