## Questions & Answers

**Q: Can I just check the maximum seat height for this chair?  I'm 6'2" and most of these chairs don't seem to have a high enough seat.**
A: I'm 6'4" (34" inside leg) and with the seat fully up, it's the perfect height for me.

**Q: How about lumbar support? I suffer from low back pain because I work 10 hours a day. I need an ergonomic chair to relieve my pain.**
A: Regarding the adjustment of the lumbar support (as shown above), first of all, you can rotate the button left and right to adjust the position of the lumbar support up and down according to your lumbar needs, so that it fits your waist perfectly and relieves the fatigue of sitting for a long time.

**Q: What are the seat dimensions?**
A: It was difficult to measure the chair due to the style (it is very curved). The base ie. the seat is 47cm wide. The length ie. from the back of the base to the front is 56cm but this includes the downwards curve at the front of the chair. The back of the chair is approximately 83cm high and again this includes the curve. These measurements are all very approximate due to the curves. I am sure that someone else will give you different measurements! All I can add is that it is a beautiful and very comfortable chair.

**Q: I saw SIHOO's latest product, Doro C300, on social media. Will this chair be sold on Amazon?**
A: We really feel your trust and concern for SIHOO. The Doro C300 has been sold and can be directly purchased in our flagship store. This Office chair is very suitable for people who work for a long time, and for people of different heights and weights
