Super glue. I buy a new toy every time because it’s too hard to remove from the walls. For beds, I drilled a hole through my mattress and installed a dedicated mount. I physically assault my landlord every time he tries to do inspections.

Liberator makes "body pillows" with toy mounts.

A hard-cover book or a mirror work pretty well

Preferably I'd get a slave to hold it steady.

Welp, I bought a Mastr Mount from twisted fantasies which is basically a silicone base plate which cen be fixated to chairs/pillows using belts. Which was okay but not good enough for me. So I bought a sex machine, fixated it on a plate and added some weights to it. That was much better👍

I have a small shelf I never actually installed as a shelf that I can suction my toys to and then just ride it on my bed. I'm usually on my knees so the bed is way better than the floor or from a semi-standing position (like against a wall or something).

I'm commenting because I literally had the exact same question while having some fun an hour or two ago and I'd also like to hear the answers people have to this question.

I have plenty of things that I can make due with, but they're all juuuust awkward enough that it takes me out of a good headspace after a little bit. It's either a weird angle, not secure and moves around, or makes me put my legs in a horribly uncomfortable position that hurts after a few minutes. Part of my issue is probably that my go-to medium dildo is a bit cheap though because the suction base on my BD toys aren't as much of an issue with sliding around.

Using the right kind if chair can work if you dont mind doing crunches.

If you want to do it on the bed, get a really big pillow and a good thick sheet of plastic, metal or wood(ones where you will never hurt yourself with ofc) and tie it on the pillow with a belt or string.

Pretty nice to ride but you need the right kind of dildo for both obviously.
