Very useful for people who tend to slide down the bed or towards the edge of their chair. These sheets are designed to assist a user to slide themselves back in their chair, wheelchair or bed to a sitting position. The slip resistant material in the base then locks into place and prevents the user from slipping forward. Top coating is breathable and waterproof and designed to be left in place under the user. Machine washable at 72°C and can be safely tumble dried. Available in 4 sizes for children, chair, wheelchair or bed.
