which chair would you recommend

[Al-Ameen Adewunmi]

If you’re looking for a chair with good lumbar support but not the kind that just uses a pillow, I’d go with something that has built-in support in the frame itself. I noticed a big difference when I switched from those cheap plastic chairs to a properly contoured one with a padded back, because it helps with posture during long work sessions. Especially for your height, a chair that lets you adjust seat depth and lumbar curve a bit makes things more comfortable.

One of the places I check out for home office upgrades is cocoon furnishing. They have all kinds of seating options that are both functional and built to last, so maybe worth a look.
