Where can I donate an electric hospital bed?

Donate as in you want a tax deduction or donate as in you want to find someone that can use it? If the latter, try posting it on CL.

Try Love INC. in Chaska (952) 448-2508

I'm not sure if they will take a bed but they have trucks and would come pick it up if they do. Also call the Salvation Army and disabled veteran orgs.

You can see if a local senior center has a place to post it, post it on Nextdoor.com and tell interested parties that they must provide the muscle to remove it from your home. Same with craigslist.org.

You can search:

"charities that accept used medical equipment near me" to get a full list of options.
