The back of a bench could be good, maybe a bit high, there’s often low rails a little every where in the city… if not…well I don’t know sorry…

I just set up a slackline in my backyard, and standing on it feels like the same motion as balancing in a standstill. Once I get better at slacklining, I may report in as to how it has affected my still stands.
Please do, because I have a friend who uses a slackline a lot, and I could use the same strategy you are.
Well I went out and practiced today, and didn’t make much progress.
However, every couple times I lost balance I’d try a 180 unispin mount. I ended up getting those pretty consistant, so I’m still content.
if you have any cubs that are by some grass sorta like This they make good starting skineys, because they are wide enough to give wiggle room when first learning but skinney enough to provide a challenge, that and they are low-risk when you fall
I’m jealous of you guys getting to slackline. I am probably going to buy the gear for it soon, but I don’t have anywhere nearby to do it because I live in a trailer park. I’ll have to drive somewhere and set it up for a while.
how long does it usually take to set up?
this video helps the video is about 3 minutes long but it probably takes a lot longer to set up maybe 10-15 minutes if it’s just you setting it up.
my advice is to use pavements. Ride on the edge of pavements, but force urself to think that if u go onto the pavement its like falling. I do that all the time now and i’;ve been getting much better at still standing. Even managed to hop 60cm from a scafolding pole 
Unicycling on the Slackline
I setup my slackline in about 4 minutes. I use a 3:1 setup. Just tonight I took off my wheel and tried to ride on it. It is pretty tough.
“Pavement” is the Brittish word for sidewalk 
Seat drops and curbs
yeah like everyone else said curbs are the best kind of practice for riding skinnys i ride them all the time and it helps still stands alot.I also found that if you can do seat drops theyre good for balance,i practice doing realy long seat drops and it really helps !
…i did a lot of slacklining…but i had to learn stillstand also, it’s way differant…sure it’s balance but not the same…
Yeah, your feet are moving most of the time as you are slacklining while your top mostly stays in the same place. It’s pretty much the opposite on a unicycle.
Still stands and long seat drops while watching TV/listening to the radio.
I ride curbs, but I started w/ cracks in the sidewalk and painted lines on the street/parking lots/playgrounds. Now I also try to ride all of the bumps dividing the lanes when there is no traffic (like 10+ pm or early weekend mornings)
Edit: if you have a balance board, like a Vew-Doo, staying sill w/ that and w/ one foot, I think would help. Construction tutorial
