## Questions & Answers

**Q: Does this chair recline?**
A: It tilts some like a rocker. It does not recliner like a recliner. The amount of tilt is small, regulated by a lever. The chair always stays L-shaped.

**Q: Are the arms of this chair made of metal or plastic?**
A: They look metal but are indeed plastic.

**Q: What is the measurement in inches between the rear of the custom (where the back touches the bottom) to the front of the cushion.**
A: If I understand your question correctly; it's 19 inches from the lumbar support, where your low back touches to the front of the bottom cushion where you sit. If I didn't understand your question, please ask again and I'll pull another measurement.

**Q: I'm interested in getting this, Is their chair hard or very soft when you sit on it?**
A: At first the seat cushion was great , but it quickly lost its shape and became very uncomfortable for me ...I had to find  a seat  cushion that seems to work pretty good for me now. I have this same problem with other chairs to be fair.
