Is the lumbar support adjustable?

No. The lumbar curve is built into the mesh back at a fixed height, so it works best for average-height users. Taller users may find it sits low on the back.

Does it have adjustable armrests?

No. The armrests are fixed. If you need height or width adjustment, look at chairs like the Hbada or Sihoo lines instead.

How much weight does it hold?

Boyel Living does not publish a firm weight rating for this model, so treat it as a light-duty home chair. It is not built for heavy daily use.

Is it good for long workdays?

It is fine for a few hours at a time. The thin seat padding and fixed lumbar support make it less comfortable for eight-hour stretches than chairs with thicker foam and more adjustments.

How hard is assembly?

Assembly is straightforward: base, gas lift, seat, back and armrests, with the usual Allen key. Most people finish in under half an hour.

Does the mesh back work in a warm room?

Yes. The mesh lets air through, so you stay cooler than on a padded fabric or leather back. That is the main reason to pick it over an upholstered chair.
