If you HAVE to buy new and that's your budget I'd say something like the below is a decent option https://www.atwork.ca/shop/office_chairs/task_ergonomic_office_chairs/hon-ignition-2-0-mesh-back-task-chair/ if you're you going to be working 8 hours a day in a chair. You want something that is highly supportive, highly adjustable, and made of lasting materials. More on reddit.com

I don't think your issue was with buying ergonomic chairs online, it was with buying cheap chairs online in general. If you would have posted that Amazon link before purchase and asked for feedback, I'd like to think everyone in this community would have told you its a hard pass. Anything bought Brand New on Amazon for <$200 is nearly 100% guaranteed to be some $15-30 cheap generic import from overseas. It would literally have to be for the seller to be making any profit on it whatsoever on that platform. Even if they were quality options, there is a reason why it is frequently mentioned that trying before buying is a very important part of the process. Does anyone know about that chair about its reliability or if it lasts long If you found it comfortable, at the end of the day that matters more than anyone else's opinions online. Now if you want some two cents... Never heard of the company before, all their models look like Private Labeled "inspired by" generic clones. Which isn't to say they're inherently bad, it just is what it is. Considering their products only come with a 1 year limited warranty that essentially only covers defective products and no usage/parts/mechanisms...this leads me to assume that they know very well that their products are not built to last very long. They even mention all warranty claims a resolved at their own discretion, no clear outline or guarantees. This is a stark contrast from the reputable industry leaders that warrant their products for 12 whole years with almost everything included aside from basic user wear and tear. Even the mid range brands with 3-5 year warranties. In the current market, I would almost always prefer to have a good condition secondhand/refurbished from a major brand that are known to last for decades over any possible option I could buy Brand New for a comparable price.

I've had a chair like that. Uncomfortable AF. Form<Function when it comes to stuff that you put between yourself and the ground (mattress, shoes, chairs)

I have a structube couch, it’s fine. I wouldn’t recommend it nor would I tell people to avoid it. The price and color were the two main reasons I got it but for a little more money you can get much better quality at Sofaland. More on reddit.com
