## Questions & Answers

**Q: is it possible to remove the arms if I wanted to go arm-less?**
A: you don't have to install the arms

**Q: Is there really a three-year warranty?**
A: Yes, our chairs come with a three-year warranty, and you can contact our SIHOO team customer service with any problems with the chairs during this period.

**Q: What kind of table is this chair suitable for?**
A: The armrests and seat of the chair are adjustable, and the height of the armrests from the ground is within the range of 24.8 inches - 28.7 inches, I hope this will help you to choose a table.

**Q: I'm getting what perceive to be conflicting answers.  Does the chair back lilt with the seat or independently?**
A: The seat does tilt back as you recline the back. However, it doesn't tilt at the same rate.  Reclining the back all the way (back 30°) tilts the seat back by about 5-10°
