I have a bed that looks like this, doesn’t have legs.
I was looking at bed risers, but they’re aimed for beds with legs. Also, the risers make the bed rise too high for my needs.
I only need to make the bed rise for about 2-inches so I can use an overbed table like .
For this purpose, I’d recommend something more like this: Laptop Desk Folding Bed Tray
That will sit on the bed, instead of under it, but will raise the surface up to whatever height is needed.
