Title: Be very careful
Review: If you don't have furniture that will fit very well into the sunken circular hole then you're better off just putting the $20 under it. I have a daybed with tapered square legs and these raised it up but it wasn't very sturdy. When I moved it a bit one of the tabs on the side popped off. From the picture you would think that this is all one piece of wood but really those raises corners are glued on and aren't going to hold anything. I ended up going at them with my drummel tool and widening and squaring the openings so that the legs would at least sink into them. Even after all that I'm glad that it's up against a wall. While the plastic ones look a little cheap at least the fact that they flare out at the bottom give them much better stability. If your furniture fits in the plastic ones go with them.
