These are very heavy duty rubberized risers. 6" tall with indents so legs cannot slip off. Lifts bed another 5" from floor. These come in very handy if you have a free standing bed and would like to store something under it. Or if you just need to raise it to make it easier to get in and out of. I used these for years but now I have a bed that attaches to a bookcase headboard. It was really nice to store my shoes in baskets under the bed instead of trying to find room in the closet. Can be picked up at McArthur Estates on Gum Branch Rd. or I can meet in Jacksonville or Richlands or Richlands. Please message me if interested.
