Definitely get a u shaped toileting sling. A commode sling has a hole in the middle of the seat area so you can go to the bathroom through it but you have to leave it in place all the time you are out of bed. You can't get it out from under you while in your chair. It is bulky and interferes with proper positioning in a wheelchair. The dangling straps catch on anything they can. The u shaped split leg toileting sling can be put under you or taken out while you are in bed or in your chair. The open area is much larger for easier bathroom use and washing of your bottom. Get one with and extended back/headrest. I found the sizing to be overly large so if close to the bottom of the size range, size down. And if you have the opportunity, tell the person who recommended a commode sling to research sings because their information is years out of date.
