Zen Phase 001 Office/Gaming Chair Review

22/03/2021

Back in the early 00’s I purchased a Herman Miller Aeron chair. For years I’ve had the joy of sitting in this chair. I’ve gone through a couple of lumbar supports and broken a bolt on the armrest, which I fixed. The mesh on the seat is worn (the seat can be replaced). However, I decided to try a new chair. I looked at a lot of chairs, including the Autonomous ergonomic chairs and a few others, but finally settled on the Zen Phase 001.

Zen Phase 001

Zen Phase 001

The chair is comfortable, and if I’d only ever sat in a cheap office or gaming chair, I’d probably be thrilled with this chair. But having been spoiled with a truly excellent chair for so long, I am hard to convince! ;)

Here are a few observations.

Pros:

  • The backrest, along with the lumbar support is excellent. (My colleague has the same chair, and he doesn’t like it at all, so he removed it from his chair.)
  • The headrest is excellent and feels wonderful. It is also easy to adjust.
  • The chair leans very far back, and with the headrest it just feels amazing. You can adjust the tension of the leaning mechanism, and it’s fine.
  • The seat can be set to move forward as you lean back. I’m still not sure if I like it or not. I use it on and off.
  • The mesh feels sort of the same as on the Aeron – but we’ll have to see if it is as durable as the Aeron’s.
  • It has a button, so that when you lean back, the seat slides forward (see cons).

Cons:

  • The Aeron’s seat is so wide (even the size B – the medium), that you don’t feel the frame of the chair – you feel it on the Phase 001.
  • On the Aeron the armrests are static and don’t move when you lean back. On the Phase 001 they tilt with you as you lean back. This makes it uncomfortable to use the mouse while you are leaned back. You can sort of fix this by pulling the arm rest towards your body, but then you have to move the armrest again, when you stop leaning back.
  • The Aeron feels much more bouncy on the seat. On the Phase 001 there is hardly any bounce – it feels closer to sitting on a wooden chair. I like the bounce of the Aeron.
  • The armrests feel cheap. The top is plastic. The Aeron’s have very comfortable leather cushions on them.
  • When you activate the mechanism, so that the seat slides forward when you lean back, your shirt sticks to the mesh, and your lower back gets exposed. A little annoying.
  • The mesh sticks a bit more to you than the mesh on the Aeron.
  • The back tilting does not provide enough resistance – you can adjust it, but just not enough – it might not be too bad if you are of a smaller stature ;)

If you’re considering the Zen Phase 001, then perhaps take a look at Herman Miller’s newer offerings. They’re more expensive, but they’re amazing. There are often second hand Herman Miller chairs to be had cheaper than the Phase 001 at new.

As for the Zen Phase 001 – yes, it’s a nice enough chair. It just isn’t a Herman Miller. The Aeron is just in another league. Much more comfortable.

“True” spread of Coronavirus

18/03/2020

I’ve been wondering about the spread of the coronavirus. We can only test so many, and we can’t test fast enough.
That led me to think. The mortality rate of the coronavirus can only be estimated, and has indeed been estimated from 0.25% all the way to crazy 20% (which I don’t believe). The latest numbers I’ve seen that make sense is the CDC estimating 0.9% mortality rate.

The average incubation time of the virus seems to be 10 days. For the fatal cases, people seem to succumb to the virus and die on average 10 days after symptoms show. This means that there is a 20 day delay. From that we can calculate the likely number of infected up to 20 days ago. For example: If the mortality rate was 1% and 1 person died, that must mean that approximately 20 days ago 100 people were infected.

Disclaimer! I am not a medical professional or statistician or anything like that. I was just interested in the numbers. The numbers are purely based on actual reported deaths and the information that I have gathered. I might even have made mistakes in my calculations, so please correct me, if that is the case.

Here is a graph showing estimated spread in South Korea from January 26th up until February 26th based on an estimated mortality rate of 0.9%

Estimated spread vs. positive tests, South Korea

Note how few was actually tested positive vs. the estimated number of infected. Total estimated infected as of Feb. 26th: 9,000

Here is Italy:

Note how few were tested vs. estimated infected. Number of positive tests hardly registers on the graph. Total estimated infected as of Feb. 26th: 278,111

Here is the USA:

Estimated spread vs. positive tests, USA

Again, the tested hardly registers on the graph. Total estimated infected as of Feb. 26th: 12,111

Based on a 0.9% mortality rate, the current number of dead – 8,790 would mean that 20 days ago around 976,667 people were infected.

It looks scary. Now if the fatality rate is high, that means there is less infected, but the number cannot be too high, since that would mean number of positive tests exceeds the number of infections. Here is the South Korea graph with a mortality rate of 6.4%:

South Korea graph with an adjusted mortality rate of 6.4%

To me this means that the actual mortality rate must be a good deal lower than 6.4%.

As I said. This was for my own morbid curiosity (excuse the pun). Take it as you will.

Also, bear in mind that this is a look, at most, 20 days into the past.

Stay safe, people!

(A) Pinnacle of First World Convenience?

25/05/2019

I just fell over a review by coffee dude, James Hoffmann, of the Ember Smart Mug. A bluetooth enabled smart mug. That you have to do firmware upgrades on, once in a while. This seems like such a ridiculous and unnecessary product, and yet I want to own one. Now I haven’t bought it, but I am sooooo tempted.

Hvad koster det, hvis man skal have én af hver i IKEA?

16/03/2018

Det var et sjovt spørgsmål jeg faldt over på Twitterhjerne‘s feed: Hvad koster det, hvis man skal have én af hver i IKEA? Klokken var mange, og jeg sumpede lidt foran computeren, så jeg tænkte at det ville jeg da finde ud af. Jeg startede med at se, om der var et sted hvor man kunne se alle deres produkter. Det var der ikke, men der var et sted hvor man kan se alle kategorierne, og på undersiderne er alle produkterne så.

Resultatet kom efter et par minutter: Der er 11.462 produkter. Det billigste koster 1,- og det dyreste 21.299,- … Den samlede pris for én af hver er 11.252.939,- Gennemsnitsprisen for et IKEA-produkt er kr 981,76 :-)

FS-LASIK treatment, part 2 of 2

7/07/2011

I totally forgot to make a post the day after. It wasn’t because I was blinded ;)
The second treatment took place the day after (on my oldest daughters 10 year birthday) and lasted 30 seconds in all, 25 seconds for the flap, and 5 seconds of corrections.
I went home and slept for three hours again, and woke up. And everything was pretty clear.
It’s been a week now, the dryness of my eyes have abated VERY much – I hardly use the eye drops. It’s really weird to be able to see better without glasses, than I could with glasses a week ago!
All in all, I can recommend the treatment. In Denmark performed by GodtSyn.dk or Memira (Memira has clinics in other countries as well).

Also I recommend that you get your eyes done on separate days – When the government in Denmark pays for it, it’s a requirement for them. I think there are good arguments to do it like that – But an obvious one, was that you can use your untreated eye while the other is closed ;)

Part 1 of FS-LASIK treatment

28/06/2011

I am far-sighted. This morning I went and got FS-LASIK surgery on my right eye. My right eye was the worst one, I had around +3 and astigmatism of around 3 buy generic accutane.2.
The operation itself took 20 seconds (making the flap) and 14 seconds of corrections – 34 seconds in all. Impressive! It was a bit uncomfortable, but not as bad as I had thought.
Right after, my vision was pretty blurry – This has mostly passed. I do have a pronounced haloing, especially around lights right now. I am hoping it will pass. It is only 10 hours since my surgery.
It’s very strange to be walking around without glasses and to be able to see as clearly as with them.
My left eye is around +2, and tomorrow I will have corrective surgery on that.

Dropbox for backup and sharing

20/02/2011

If you aren’t using it already, I can only recommend installing Dropbox. You’ll have backup for your most important files and can share with friends and colleagues. Join with this link: <a href="http://db additional resources.tt/xMmuInC”>http://db.tt/xMmuInC – If you use that, I get a little extra space in my dropbox :-)
