I purchased a new metal bedframe a couple of years ago. I LOVE the headboard and footboard so much. I searched months for this frame and when I found it, I was so excited. Unfortunately, the head and foot board were perfect, the frame was kind of flimsy. The "feet" had to be screwed into the slats and I knew from experience, they were not going to last. It's just a poor design. So a year later, I'm dealing with some squeaks and shifting, I removed the mattress to check the frame and sure enough, the little feet had bent away from the frame. I was so bummed. My husband wanted to trash the whole bed but I refused--it took me weeks to find the style I wanted and I wasn't going to throw the whole bed out because of the poor design of the frame. So I searched for a solution and found these risers. They were cheap enough I could give them a try and return them if they didn't work out. Well, guess what--they worked awesome! I put some of those felt sticky pads on the bottom to protect the wood floors. You can use the round side of the riser to use on the feet of the frame or you can flip it over and there is an area for the slats/frame to be supported. I used that side and just placed the blocks where the little metal feet had been. Now I get to keep my headboard! I'm so happy. I'm thinking of getting a few more to put on my daughters bed because hers has those same metal feet and I know they will just bend too. These are so sturdy. It makes a huge difference in the way the mattress sits and the sturdiness of the bed. Solid purchase!
