That sinking feeling. Height adjustable chairs.

[Mike Halmarack]

I set out to do a web search on remedies for the sudden descent of 3 of my telescopic, height adjustable chairs but couldn't think of the name for such mechanisms. Please help me out here.

gas spring/strut/lift

In my case, it's eating too much.

I was built like a blimp on two sticks not long ago. Then I performed the appallingly fashionable act of cutting gluten out of my diet. Now I'm slender and getting more sylph-like daily. So, I do think it's a mechanical problem with the chairs.

Like car struts, they can loose their "oomph". Replacements are available, sometimes of different lengths which can be useful.

Interesting. I was 13 stone at the start of the year but am down to 11st

7lb, mostly just by reducing carbs (esp. home-made wholemeal bread - very sad); my waist has gone from a tight 36 to a comfortable 32 and the BP has gone down a bit. I'll be happy when the scales stop saying "one at a time" and when the weight starts with a 10.

I never did like the ones you pumped with a paddle like lever, since they tend to suddenly raise you up more than you wanted, then start sinking hour by hour. I guess the valve mechanism tends to get worn after a while. Brian

Home made bread is one of the highlights of my life. I thought I would miss it more.

This chair is only about a year old, from Lidl. It's a minute by minute let down experience here, rather than hour by hour. I do appreciate Lidl vegetables though.

Something like

which I got when my WFH chair kept dropping.

[Mike Halmarack]

Thanks for that. Big help.

[Mike Halmarack]

Nice one, thanks

It winds me right up.

Who adjusts the height of a chair anyway? I'd prefer a set and forget system, I wonder if it's possible to replace them with a screw?

[Chris Green]

Once upon a time they *were* adjusted that way, you'd see people whirling their chair seat around to raise or lower them.

I read somewhere that inverting the chair so that the gas strut lube oil can run down inside the cylinder and can help to improve the seal between piston and cylinder. I don't know if it works, but it's cheap to try.

[Steve Walker]

We have a PC in the living room and I also use my work laptop via the same keyboard, mouse and monitor. That means that both I and my wife use the same chair multiple times in a day. As she is 4'11" and I am 5'10", adjustment is needed!

On days that I am in the office, we do not have reserved desks, so may also need to adjust the height of seats on arrival.

[Max Demian]

How do you fit it? Usually the gas lift jams into position when you assemble it.

(Mine gradually rises so I have to make it drop every couple of days before it jams under the desk.)

[Max Demian]

As I suspected, the main problem is removing the old one, needing a big lump hammer, WD-40 and some way to support the chair.

[Max Demian]

The gas lift makes it soft and bouncy when you drop onto the seat.
