Varies _a lot_ depending on your local market. Here in Finland used Herman Millers and Steelcase chairs _exist,_ but they are nowhere near as plentiful as in the US or UK, and consequently used prices are a lot higher. Hayworth and Knoll, and many other brands are completely unheard of here. It took me two years of listening for deals to find myself a moderate condition Mirra 1 for 250€, and I know that sounds like I got ripped off compared to US/UK prices, but on this market that's a steal - these rarely go under 400€ used (and when they do appear, they're usually gone in literal minutes), often closer to 600€. Still better buy than any Ikea/furniture store/gaming chair I've been using in the past.
I've been using my Ikea Markus for about 4 years now. It's incredibly durable considering my use - most chairs don't last longer than 2 years (I'm extremely careless). I don't like the level of comfort, but I know that I'd fuck up a more comfortable chair in under a week (I did that to the backup chair I bought just in case). If you're looking for durability and want something brand new, consider Markus.
Hmm used a Markus for a while and was so thankful I switched to a better office chair. The back is not very flexible and the adjustments overall are lackluster I feel. If you are fine with it then ok to keep it but I promise you you are missing out on a lot of comfort not trying out some other used ones on the market in your local area
I've bought used office chairs in the past, and I highly recommend it. Got a Herman Miller Mirra 2 with all the extra features for $100 US and a Steelcase Please 2 for €85. Neither was pristine, but I got each of them on pretty short notice, so if I had a little more time to be picky, I think I could have found something even nicer. The Mirra was my absolute favorite chair, super comfortable, really well made. It did have a little tear in the mesh, but it didn't affect comfort/usability and it didn't worsen at all for the 4 years I had it. The white/light gray parts were a little discolored, but it still looked nice. The Please 2 was also good. The upholstery looked 98% like new, but the gas cylinder could've used a recharge, and the legs had some scratches on them. I didn't realize the armrests were connected to the lumbar, so when you press down on the armrests, the back of the chair pushes into you. Not a huge fan of this, but it's still much better than anything else I could have gotten new for that price.
Something not mentioned here is that office chairs often have a lot more adjustability than cheap "home office" chairs. At work, my chair looks very simple, but in addition to the standard lift up and down, and back tilt, it also allows the seat to tilt forwards or back, the back rest can be raised or lowered to place the lumbar support in the right position, and the lumbar support can be inflated or deflated.
Agreed so many companies bought great chairs for employ to work at home throughout Covid. Its awesome people didn't pay 1k for them so they have little attachment to let them go for £100. My decked out £1,244.40 Orangbox Eva cos me £120
I did. I got a open box Hon Nucleus with a chipped rubber armrest for $100 a few years ago and it's till good as new. I just put on aftermarket armrests that are more comfy than the stiff originals.
I know what good office chairs are because I've had to buy and sell a lot of them. I sell single office chairs to occasional people in the UK lol, I'm not being paid by any companies
