Economy Skidders are used in the same way as the regular skidders but have less of a ridge around the outside and are more flexible.  Skidders let you move furniture with little effort!  Now it only takes one person to move heavy furniture.  Use Skidders on carpeted areas.  Simply place one skidder under each leg of furniture, then slide.  It's like magic!  No back injuries from lifting.  No more broken furniture legs.  Just slide it with Skidders.  Carpet cleaners use several sets of Skidders.  Leave Skidders under furniture, replace with blocks or carpet protectors after cleaning.
