even that expensive.

hey, I was shopping at 'Overtoom', where they deliver before you put down the phone. :-)

How about these?

No wheels, but feet, no shootin gaway of the chair!

I thought physicists were measured in stones?

Note that there are office chairs for "big and tall" people that might be more suitable for such physicists. For example:

Seat belts, roll bars, and air bags are optional.

Wow. I found a suitable drafting chair for the workbench:

I want one.

Taking about g forces and ejection stools, been writing drivers for the MPU6050 acellerometer module from ebay.

The module works now.

The hole in the ceiling needed for the ejection seat makes that choice a bit problematic here. If you go that way I recommned you also get a helmet in matching design :-)

After the last .com bust, the local charities stopped accepting office furniture. And foosball tables. I'm expecting that situation again soon.

Proper office chairs are not supposed to shoot away! The wheels should have a braking mechanism which prevents te chair from rolling no more than a few centimeters. Do yourself a favor and look for a shop which offers used furniture and get a real office chair.

Brakes? I don't believe I've ever seen a chair that will only roll a few centimeters. Wheels should be matched to the flooring, however. What works on carpet is not safe for vinyl flooring and verse visa.

Most likely, but a 1yr warrantee and reasonable price for a decent office chair is worth it. Note, it is an air-cylinder type, so expect that ball seal to wear thus the chair to give you a SSSinking feeling. If you do not adjust it 5-10 times a day, but (say) only once per day or less, it should last beyond the warrantee.

Sand leaks out and is too "obvious" as it makes the envelope too fat. Instead, use sheets of metal cut to fit to add maybe 8oz; i heard that too much weight will allow them to reject it and not pay postage. But if it weighs less than that (unknown) limit, they pay dearly - well over a dollar. Make sure your name and address is on a sheet wrapped around the metal, saying also "NO" or "NO JUNK MAIL". Eventually the word gets to the bean counters..

More of the same:

Never mind conventional seating for conventional minds. These are for rocket assisted power thinkers.

Link expired. Here's the replacement:

Hmmm... 1/3 the cost of the original board:

That's what they always say just before the customer finds the first bug.

Well, if you're using the module as part of an inertial guidance system, you must obviously be building a guided missile. Might as well cut the holes in the ceiling and roof now, as you'll need it for both the ejection seat and the missile launch. If anyone asks, tell them you're building a "sun tunnel" skylight.

OSHA (USA) made Microdyne replace the few they still had last millennium, stating that they fell over if a wheel broke. Rather than replace about 30%, the production floor got all new chairs. That was cheaper than dealing with the assemblers bitching, 'Why did SHE get a new chair, and I didn't?'

I have several of those with worn out hardware. You have to spin one up every few days, and the other is no longer adjustable with a pair of

'shit stuff'.

Some of those folding chairs are only raded for 100 pounds, and are intended for use by children. Not that people pay attention to the labels. Then they break chair after chair.

These are made with heavy aluminum frames. I've been in the factory.

Do they keep alligators there?

The old all steel Lyon bench stools lasted for years. Mine are over

I bought mine used in '75 from a surplus dealer (Mendelson's) in Dayton, Ohio who had just bought the old NCR mechanical cash register factories. I had some padded seat covers made, and one has an adjustable back. I've logged thousands of hours on those, over the decades. I've used them for sawhorses, ladders and other things that would destroy most chairs.

This is similar, with a tool tray.

Where is the fun in that? I had a jerk US Army Lt. in my way one night at a military TV station. I had told him to get out of the control room before he got hurt. I told him several times, but he wouldn't listen. I was about to call and have him arrested for tresspass in a controled area when projector failed to start. The heavy old '50s style office chair started to roll backwards as I jumped up. It would normally roll to a couple feet from the relay racks on the other side of the room, and out of my way. The large knob on the back hit him in the balls, and he let out a sharp gasp, then he took step in the wrong direction. I ran into him and sent him sliding across the floor, as I jumped over him to get to the projector. I had it running in under two seconds from the failure, but it took him much longer to recover. When his breathing finally slowed down he said, "Nice reflexes, soldier!" He sat on a stool in the corner after that. ;-)

No need in Central Florida, since we let them roam free to help control the excess tourist problem. It's fun to see them ignore the signs warning them that the gators are dangerous. They also like to eat annoying little dogs.

We used to use monkeys, but it was a lot of work to clean up after them. They were descendants of the ones used in the Tarzan movies.
