You might wanna search through this thread for the chairs/brands you want more info on. Other forumers have given some comments about Merryfair, I think generally positive review

🙋‍♀️No I don't have that problem. It's supposed to click to specific positions though, just like the headrest/armrest adjustment. Did you hear them clicking as you adjust up/down?

I'm Sihoo M57 user here. It took me a while to get used to the mesh sensation, but I pretty much just relax with my usual short pants. The mesh "prints" onto my skin and takes a while to... disperse, but it's nothing uncomfortable. Never got any sort of injury/scraped off skin using the chair.

Additional note:
My workspace is not air conditioned and can get very hot when I play games. The mesh seat is a lifesaver for such heat; I can't imagine sitting on a leather seat. I'm not saying it's like sitting in a cool shady forest, but the mesh really doesn't accumulate heat and cook you from under/back unlike leather.

Judging from the 3 types you shared, it seems you haven't decided what type of material you prefer: mesh, leather, fabric etc. I personally recommend mesh (and using one myself).

Comfort: mesh doesn't accumulate heat like leather (worst) and fabric would. In terms of material softness/"nice to touch", it's not as good as fabric because it generally feels harsher... But rest assured, it doesn't prick or rub your skin in the wrong way.

Durability: I can't tell yet because my seat is only 1yo... But so far so good la. I hate leather because I sweat quite a lot and leather requires more care, else it deteriorates real fast and bad.

Once you've decided on material, you'll be able to narrow down your selections. Generally, the seat should be adjustable in as many ways as possible to get the best fit. To give more perspective, I'm using Sihoo M57 which is within your budget (?) But doesn't have adjustable armrest width wise so the seat becomes too wide for my arms to rest properly:(

Hey there, I've been using it for a year+ now. Generally happy with it although I have to say cleaning is kinda troublesome... I just wipe the outer layers mostly....

Ahh my home office can get very dusty y'see... I'm even embarrassed to prove my point 🙈

Maybe one thing might come handy for anyone who gets Sihoo M57 and have dusty environment like me: use air compressor to blow the dust that settles at the compartment right below the mesh lol.

Heyyo, I wrote a review on M57 some pages back. You can go to desktop version and find my posts for it... In short, I'd say get V1 if you have the budget.

The seat doesn't sink if that's what you're asking.... I don't have an ergonomic workstation to pair well with the chair, so unfortunately my shoulders/arms do sore a little after a long time.

Not at all. I'm not sure what's the material.... Definitely not leather so the skin won't peel off like old leather lah. But not fabric either, it's too hard for my liking but you can press it down geh, maybe rubber?
