Which aneros model can be used while sitting?

Use your elbows to take your weight off the chair. Or sit on chair with top of ass off the edge of the chair.

They’re not really made for this. They’re not comfortable when sitting. Maybe the silicone ones are better or in the aneros modification thread you can get some ideas. 

the only way I could picture it working for longer amounts of time is if you get something that you can sit on that will leave a gap and stop the tabs from gouging your skin. Maybe two cork yoga blocks could do the trick or a u shaped firm support pillow. For shorter use, Helghast mentioned already good options. 

Something like a hemorrhoid pillow might work with a lot of different models, I've read, especially the new Trident models. 

You want to be sure to use something incredibly sturdy and rigid for sitting on a pillow or something soft as far as I know, and the only material I can think of is the traditional white plastic. NEVER do this on any of the ice or electronic models, and I'd be cautious about even doing it on the silicone ones or even at all. The Aneros was made to float in your rectum and be dynamic with the muscles of your pelvic floor. You don't want to risk injury by doing something that it isn't designed for.

I think the DeVice is actually meant to be used while sitting. It is mentioned in the product description if you want to check it out.

There are prostate plugs suitable for sitting on them. But not from Aneros. The Peridise work for that, kind of...

I once had the same objective of finding me a plug for sitting on it. I found the icicles No. 45 and it works perfectly for that job. One of my all time favourites. It's a well made inexpensive glass plug, roughly the diameter of the progasms. But it's hard to get nowadays. 🙁

I have had success with any of the Syn models in a sitting position. All are soft and the flexible tabs stimulate while in this position. In a public setting not recommended due to lube and possibility of falling out!!

I've had success with all of the Peridise models along with the Tempo. To me its very comfortable while sitting and pleasurable as well. The syn models like the Eupho and the MGX are very comfortable as well. But you have to keep in mind that I have a very soft and comfortable chair. I'm not sure if that makes a difference or not, but for some reason I think it does. I guess what I'm trying to say is experiment and see what works for you. Start with the Peridise models and go from there. Good luck on your journey. 

Unfug thank you for mentioning the Icicles #45. I am one of the lucky ones that has one of them, and I never considered using it for sitting. I am sitting here now typing this message and enjoying the  p-waves that are building in my body! It is wonderful!

I have often wondered if there could be a prostate massager that could be fully inserted with only a string to retrieve it.....like the jade egg that many women use.
