A furniture spacer having a rigid flat construction is configured to rest on the floor between the base of a wall and a piece of furniture such as a chair, sofa, table, or cabinet and the like to keep the furniture away from the wall and prevent it from hitting the wall or window and causing damage. Since furniture comes in many sizes and shapes, with different degrees of lean from the leg bottom to the most rearward part of the furniture it is desirable that a single such spacer accommodate a wide variety of furniture designs, including legs within a reasonable range of widths and shapes, which the particular shape of the described spacer is able to do without significant effort on the part of the user.
