Great video. I have just bought my first seat slide chair. Only due to fact that can't rely on retailers when quote seat depth as they mostly don't deduct the thickness of the backrest from the seat depth quoted.

Thank you so much for this video! I bought the steelcase leap v2 about 2 months ago now, and I've been having consistent discomfort with it no matter which area I adjusted. The thing I never adjusted was the seat depth though. I was under the impression that since I'm 6'3, I should have it all the way forward. For the past few days, I've had my seat depth 2 clicks back from the most forward position. It has helped dramatically!

When you made the gap between the seat and back rest I was like "yes! this is exactly what i want!" And then you said "no one wants to sit in the gap," which made me laugh, because me and my huge butt disagree! Most chairs that i have encountered (which is not that many) do not have enough of an adjustable range for lumbar support on their own, and so i rely on the adjustable seat depth to create more of a gap, so that i can actually get the benefits of the lumbar support. I do agree with you on the point that this can cause too much pressure toward the knee. But for me, the back support is more important, and i can mitigate the pressure problem by getting up and walking around for 10 minutes every hour. Sadly, most chairs that fit heavy people are also designed for tall people, there aren't really any options for us short heavy people.

Holy... I'm about 6'0 and I've struggled with my Humanscale for about two years... I've tried to be warry about having it too far in any direction and have tried doing calculations (divide height range (5'0 - 6'4) by number of clicks seat pan can go back (9)) to find what should be the right setting for me, thinking it's about two to three clicks back. I was aware that it may not scale linearly but still assumed this information to be about correct. But upon trying the seat pan ALL THE WAY BACK I immediately feel very very different to how the chair usually makes me feel! It's like I don't even feel anything on my back, it's insane. I'm going to increase the seat depth from here, obviously, especially since I feel not too amazing leg and shoulder wise at the moment, but wow! Thank you!

Bonjour Olivier, je vous remercie énormément pour vos vidéos qui mon aider à améliorer la qualité de mon quotidiens, je discute souvent maintenant avec mon entourage sur comment avec quelque geste nous pouvons rendre notre journée au bureau plus agréable. Même durant mes stream je me retrouve à discuter d'ergonomie au lieu de discuter de jeux ahhah ^^ Merci encore de partager vos connaissance sur youtube o/

Hi Olivier Many thanks for all your videos! When I sit in my office chair for some reason my calf muscles start to hurt really bad, particularly on the sides (the peroneal muscles). I was thinking maybe this is because of the depth of the seat as I am also a petit user (5.1 ft). What do you think? Maybe there are other reasons behind my pain?

Hello. I have a synchro office chair (operators chair) which I have a hard time finding a comfortable position adjusting to fit me as a petite user. How do I find the correct angle of the seat pan so my weight is evenly distributed when sitting? I have suffered with typical neck shoulder pain for 3 years. I look forward to hearing from you.

Hi, I have a Herman Miller aeron size C. I'm 6'2" in height and have 3 fingers width between the back of my knees and the edge of the seat. Unfortunately the seat is causing intense pain on the bottom of my thighs after sitting for only 20 minutes. I have the seat height at 18 inches to achieve 90 degree angle between knee and hip. Any recommendations? Thanks.

which chair can u recommend to buy ? price is not a problem

Can you recommend a chair for a tall person 205cm 105kg ? I like Jarvfjallet from ikea but depth adjustment is not deep enough. Im located in US.
