The ideal seat height for foot percussion is significantly higher than a typical chair. I've tried a few things over the years:

• Stacking chairs: works great, until you come to a venue without any stackable chairs.

• Drum stool: good (unless you buy a very cheap wobbly one like I did) but heavy and not good for flying with.

• Adjustable booster: ok, though unavoidably bulky and the one I made is also too heavy for flying.

At Hashdance Weekend Kelsey had a set of furniture risers she let me borrow, and I liked them a lot! I decided to get a pair.

They do slide around a bit, though, because they're hard plastic on the bottom:

I decided to put on a layer of silicone for better grip. I roughed them up a bit with 220 grit sandpaper:

And put on a thin layer of old silicone from what I had left in a tube from a bathroom renovation:

It's certainly grippy, but it turns out not very robust. Here's after my first gig with them:

I really like how light and compact they are, and a bit of sliding isn't a complete dealbreaker, but I would still be a lot happier if they'd stay put under me.

I was thinking of maybe using cyanoacrylate to attach a thin layer of rubber, probably from an old inner tube. But I'm worried this might mark the floor. Suggestions for things to try?
