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 .
Maybe finding a differently designed table is the way to go. Perhaps someone makes one where the base is intended to be tucked under the box spring, for example.
Maybe attaching the table directly to your bed frame is the answer, rather than raising your bed.
Regardless, don’t restrict yourself to Amazon. Look at websites for medical supply companies. I would expect them to have more varied solutions.
EDIT:
Maybe something like this https://www.medline.com/product/Pivot-Top-Steel-Base-Overbed-Tables/Overbed-Tables/Z05-PF08581?question=overbed%20table
Disclaimers: I don’t know what your budget is, or what country you live in. Yeah, it sucks that the website makes you log in to see prices, but least it’s Medline. They’re a big name.
Or just get a hospital bed.
