Thoughts on Sihoo M76?

Hi! So planning to buy this chair tomorrow lol.

May nakabili na ba nito here? I see a lot of reviews for the SihooM57 but not a lot for this one. Personally I like it better kasi, it’s almost 4k cheaper and is smaller/less bulky kaya kasya sya sa narrow working space ko. But wala masyadong feedback sa pagiging ergo nya. Sobrang sakit nadin kasi ng likod ko so I want to upgrade from my gaming chair. Thank you in advance!
