How to Make a Seat for Less Than 8 Eur in Less Than 4 Min.




Sitting all day sucks, because it causes back pain sometimes. Standing all day sucks as well, because it causes tired legs after a while. So while working at Open Design City today, I was wondering how to solve this with a very low budget and without a lot of time. So I came up with some kind of seating, and I thought I´d rather share it with you quickly before it get´s lost, as some kind of immediate project documentation. And if you want to make your own, this is how it works.

Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: What You Need.

What you need to get:


- 1 old bicycle saddle, 0,00 Eur (recycled)
- 80-95 cm of roundwood, pine tree 22mm, max. 4,00 Eur
- 1 plunger, ca. 4,00 Eur
- 1 wood screw


- Saw to cut the roundwood, if necessary
- Sandpaper
- Srewdriver
- Wrench

What you need to do:

Remove the stick from the plunger and replace it with the roundwood. Grind down the other end of the stick to 18 mm and assemble the saddle. Push the plunger down to the floor, so it gets sucked down and the seat doesn´t slip away.

Step 2: Cut Roundwood.

Depending on your body size you will need a piece between 80-95 cm to sit comfortably.

Step 3: Grind Down One End of the Stick.

Grind down one end of the stick to 18 mm using coarse sand paper in order to attach the saddle.

Step 4: Attach Plunger.

Use a woodscew to attach the plunger to the stick. You might want to drill a whole first to make it easier to tighten the screw.

Step 5: Attach Saddle.

    Ive been thinking about building one of there for fishing. Clip it to my utility belt that holds my beer and tools.

    I love this! My mother in law teaches junior high and I'm going to suggest these to her. She has the same problem with kids leaning back in their chairs.

    @ the norm - I can't stop laughing at your suggestion to forget the saddle. You're right it shouldn't be necessary but gosh that would be a funny sight.

    Hmmmm........ I wonder if I could fit one of the used shock absorbers from our cabs between the seat and dowel. Maybe even dress it up to look more steampunk.......Hmmmmmm....... ;) :P :)

    Many old farmers use a similar idea, a stool with only 1 leg, and strap it on with an old belt. that way you can sit to milk your cows and get up with both hands free. So, add a strap! I can just see it now, HAHAHA!

    I've been sitting on a swiss ball in my examination rooms for years but twice now they've eventually popped - bad for the disks. Now THIS seems to be a great answer!

    Well, this saddle is a left over piece from an old GDR bike and it was for free. Second Hand saddles are available very cheep - at least over here in Berlin ...

    I've been thinking about something like this for some of my fifth grade students who constantly lean back in their chairs. I was thinking of the bike saddle and thick dowel (or pipe), but then just capping it with a large rubber cap. I suppose the advantage of the plunger is that it stays stuck in one spot. I could see it being perceived by my kids as a reward rather than a consequence and them wanting it.

    Why does it have to be a consequence?
    They have those big balls for kids to sit on for what used to be called riggly bumb.
    Just have them sit on this, make lots to go around.
    If you really want it to be a consequence, then forget the saddle part, but I don't think that should be necessary.


    True. I'm not a tyrant and generally let many things slide. I have found, though, that eventually, on these slick floors, the chairs slide out and kids crack their heads on floors and/or other desks/chairs. While it is true that experience is the best teacher, I'm looking to prevent injuries when possible. Also, their reclining posture is not usually best to help them do the work we are doing. Sometimes it is, which is why I have a couch and loads of cushions in my room, but not usually. SS

    Epic chair of plunger... Though It could damage a floor, like a wooden one... Not a real problem I guess for stone or tile... I've nearly took a wall down with a plunger

    I like the design, I've seen single-leg stools used as a form of ADD or ADHD therapy, to help kids with it concentrate while working. Although if you're using it to reduce pain from sitting all day, you might want to consider using one of those wider ergonomic bicycle seats.
