I've been using a Salli chair for 3-4 years. I can't say anything about actual effectiveness, but can give some anecdotes.

* It doesn't force you into a straight-back posture, but it makes it as easy as slouching. If you stop concentrating you don't fall into a poor posture.

* There's really only one way to sit on the chair, with your sit-bones taking most of the pressure. In a normal office chair I can switch between a set of different slouches to move the pressure between points, but not with this chair. I bought a height adjustable desk to compensate and switch between sitting and standing several times a day.

* It takes a fair amount of strength. I don't remember if it took me time to build muscle initially, and on a day to day basis I don't notice any tiredness or anything, but when I'm sick it is _really_ hard to sit on this chair - I feel like I'm going to pass out (maybe not to that extent, but it's quite noticable).

* I bought the first one for $800, but AFAICT they've come down to $300ish this year maybe due to competition. They're sturdy and really nicely built, but in the end it's just a stool with some curves.

* May or not be related, but I found my back getting really stiff because it is literally straight all day - sleeping, standing up, sitting on the Salli chair, etc, which worries me a bit.

* You sit at a much higher level than with normal chairs, so you'll need a higher desk to accommodate.

You make it sound so complicated. Are you overweight? When I got my first Salli Twin due to sciatica I was sitting 14 hours a day on it in the first week.

Also, the expensive models are made in Finland while the $300 models are made in China for the outside-EU market.

Well THIS certainly is not a sentence I ever expected to read on HN!

Sitting on anything 14h/day is a recipe for disaster!

The same goes for standing if one has a standing desk, and for any other position.

You should vary your position regularly (every hour, for example). The simplest solution for this is a desk where the height can be changed easily (maybe with a motor), so one can sit for a while, then stand for a while, and so on.

I've seen desks like this at Staples. There's a simple linkage, and the entire desktop raises.

The simplest solution is a chair made for a standing desk.

I’ve done that but I never liked the lack of options for foot position. You either have your feet tucked back on the foot pegs or they’re hanging. Neither were optimal for me (maybe partly because I’m tall and having my feet on the pegs felt like i was “tuck g up”.

I know what you mean, having had to use those chairs myself, but a less than ideal chair is a less than ideal chair.

I only had to use the 'bad' chair because the good ones - with a proper foot rest - had been snagged.

With breaks and exercise of course :P

Also, I have an extra Salli Twin I use while cooking and doing dishes in the kitchen.

> getting really stiff

Do you stretch?
