I searched for several months for a new desk chair. I finally found what I wanted in the s4 Welax ergonomic chair! I was primarily concerned with how it would fit my body and it is perfect! Customer service helped answer some questions I had and were very helpful and respectful. Thank you for such a wonderful product!

Best Chair
This is the first ergonomic I’ve owned, and it is awesome. I’d suggest it for anyone with sciatic issues. I usually get dead foot after sitting too long, but not with this chair. It’s nice to have the footrest too when I need to kick back a bit.
Setting it up was pretty easy too.
