Writing this in hopes it helps someone out. I bought the Herman Miller New Aeron because I wanted a top-tier chair for my computer room. Since I'm so used to floor-sitting, my 'turtle neck' was getting bad and my posture was trash. I heard the Aeron was expensive and great, and I figured the priciest must be the best, so I used it for about a year. I've sold it secondhand now. The biggest con of the Aeron was that my butt kept sliding forward and the chair felt like it was constantly pushing me out. If you sit in perfect 'textbook' posture, it's pretty comfy, but the moment your posture slips, it doesn't support you—it just rejects you. Even though I dropped 1.6M KRW plus another 100k+ for the headrest and tried to power through thinking *I* was the problem, it was just too hard to sit in for long periods. So I decided to sell it and hit up a Sidiz shop, which is a pretty famous domestic brand. This time, I vowed to actually sit in them before buying. I bought that expensive Herman Miller without even trying it first, lol T_T
Since I'm an Incheon local, I visited the Sidiz shop near Juan, and it was awesome because I could test every single chair. I ended up picking the GC PRO gaming chair. The thing I loved most was how the seat base slides forward. This gives a massive sense of stability. In a normal state, it keeps your posture straight, and if you slide it forward, it stays comfy even for long sessions. Since this one also costs over 700k KRW, it has all the adjustable armrest features like the Herman Miller. After trying everything, I realized 'expensive is best' still applies, so I went with the high-end gaming model that includes the cooling fan. I thought I'd have a bunch of cash left over after selling the Herman Miller and buying a 'cheap' Sidiz, but man, the good Sidiz models are pricey too. Anyway, bottom line: if even a Herman Miller felt uncomfortable for you, give Sidiz a try. I'm finally not dreading long sitting sessions anymore.
A quick add-on: the Sidiz GC PRO has two extra options—a ventilation seat and LED lamps. I skipped the LEDs, but since I sweat a lot, I got the ventilation seat. The problem is it's designed to run off a power bank, which is super annoying to manage.
Tucking a power bank inside looks clean, but the hassle of recharging made me look for a way to hardwire it. I tried a long USB cable to my PC or a charger, but it wouldn't work. I asked an AI for a solution. Basically, you need a USB-tipped adapter that provides stable power exceeding the seat's 5V 2A requirement. Apparently, if you use a regular USB cable to a PC or charger, it gets flagged as a 'malfunction' and won't send stable power. Interestingly, a 5V 3A setup with a long USB extension failed because the amperage dropped. Short cables worked, but since the chair needs to move, low amps were a no-go. My final conclusion for the specs: must be an adapter (stable power), must have a USB tip, must be a decent length without extensions, and 5V 5A to handle any length. Found a product that fit.
I hooked it up with a product that met those specs and it works perfectly! I'm just bored on a weekend so this post is a bit all over the place, but I hope it helps someone out!!
"A heated debate over the 'Aeron elitism' vs. practical comfort. While some defend the Aeron as a posture-correcting holy grail, others find domestic brands or even the famous 'SNU chair' better for actual home use. Also, the classic 'headrest or no headrest' debate continues."
