If you EVER need to move furniture you MUST purchase these.  I found them at Bed, Bath & Beyond for about $20.  They’ve been up in my closet for quite awhile (actually forgot I had them).  Pulled them out yesterday to move my bedroom furniture around.  They come with elastic Sherpa like covers that you can use on hardwoods or just take them off for moving furniture on carpet.  I can’t even tell you how easy it is – they will blow your mind!! Really they will!
