OT: About chairs

PS this one was 5 Euro from 'gamma', I call that shop 'gammel', the Dutch word for 'not so stable', or short for 'shit stuff'.

Buy a swopper.

Looks OK, but a bit pricy here:

About 585 Euro...

For 5 Euros, I'm surprised it had 4 legs.

Your problem is that your chair budget appears to only be one euro per leg. Even small dogs can break such a chair.

If it really is the numbers you gave, then don't cry about the 585 euro chair you were given as a recommendation.

I use a pneumatic adjustable 5-wheel lab chair that I got for about $100 at Staples.

Works great--I can adjust it up when I use the Mantis, and down when bifocals are enough. (I have the original Mantis, which is longer in the body than the little one that JL uses. That's okay, I'm a bit longer in the body than he is, too.) ;)

I've got a adjustable 'stool' type thing. I can keep some weight on my legs and not all on my (rather small) derriere (kind of a gluteus minimums).

It doesn't matter how much you pay for chairs, they will break in a few years. Metal tears, fasteners pull out, bushings fail, padding splits.

But refrigerators last and last. That's counter-intuitive.

What posting?

Yes 5 wheels sound like a good system. We have no 'Staples' here, but I have seen some on the internet that are not even that expensive. Thanks.

'shit stuff'.

That's because your system doesn't allow for Romneys.

I don't know if you have office equipment stores or better, used office equipment stores but they're in every decent sized city here. They sell "professional grade" office furniture for about what the home stuff sells for. Such a chair will last a home user a lifetime.

A chair with wheels will make it difficult to put all your mass on one leg, or produce unusual loads. Any small diameter tubing, with a hole drilled through it for a hinge, is going to provide a stress riser at the hole. I suggest non-folding welded construction as a better design.

No. I have two chairs. One is a very low "medical office stool" which brings the bench top to nose height, my favorite soldering position. Something like this:

The other is a much higher antique "drafting stool", so that I can comfortably see the pile of test equipment on the bench. Something like this:

Both were purchased used at several possible thrift shops or garage sales. Actually, all of the furniture in my house and office were either stolen from the parents home, or purchased used.

Mine are at least 25 years old. Again, look at the construction for mechanical design defects. If it looks like it will fall apart, it will eventually fall apart.

That means you're not expected to sleep in the chair.

If it was made in China, it's automatically a throw away. It's almost impossible to purchase anything of quality these days as everything seems to be cheaply made in China. That's why much of my furniture is old, heavy, solid, and difficult to break. Usually the old stuff has upholstery problems. Some foam, heavy cloth, a staple gun, and maybe some hog rings, will solve that problem.

Hint: Avoid chairs that help generate static electricity. A vinyl (PVC) seat cover, and cotton or wool pants are not a good combination when the humidity is low. Bring a neon lamp (NE-2) when shopping.

Huh?

'shit stuff'.

I see no one asked the obvious question:

What is your weight ??

or 'shit stuff'.

Not surprising. The holes in the legs acted as stress concentrators and the tubing wasn't strong enough to withstand any weight shifting. A chair welded from solid rod might work better, although welds can be stress concentrators as well.

I would suggest a section of tree trunk, wide enough to be stable as you gyrate, and high enough to be comfortable. No way could you break it, and no arm rests.

for 'shit stuff'.

I just assumed 1/8 of a ton.

'shit stuff'.

even that expensive.

These are pretty good.. ESD-safe and clean-room compatible. Nice back and the ring near the base gives a spot for the feet to rest.

Around the equivalent of EUR 350. They won't collapse even under heavy loads (field-tested using a large physicist).

Ya, similar to my thoughts. Build a plywood and 2"x4" box and put a cushion on it. Make a slot big enough for your hand on the side to make it easy to pickup and move. Mikek

We load-tested some Adirondack chairs (cost $20 each at Mountain Hardware, much assembly required) using a standard Large Physicist Test Mass, and they survived.
