I’ve used transfer disks with my mom and they work well. The standard disk I would only use when my mom was able to safely walk a few steps and there were grab bars around.

More recently I’ve used this successfully with my mom. As long as the patient can stand then this will work great.

Edit: you can also look into transfer boards as a cheaper option.
