No longer is strenuous lifting needed to move furniture. Skidders let you move furniture with little effort! Now it takes only one person to move heavy furniture. Use skidders on carpeted areas. Simply place one skidder under each leg of furnitur, then slide. It's like magic! No back injuries from lifting. No more broken furniture legs. Just slide it with skidders. Leave skidders under furniture, replace with blocks or carpet protectors after cleaning.
